Abstract

Stojaković M., M. Ivanović, G. Bekavac, A. Nastasić, B.Novaković, A. Purar, B. Mitrović and D. Stanisavljević (2012): Evaluation of new ns maize hybrids using biplot analysis . - Genetika, Vol 44, No. 1, 1 - 12.

The study analyzed two-year results of a testing of 20 new maize hybrids from FAO MG 600 as compared to a standard. Data on the hybrids NS6683, NS6686, NS281633, and NS396432 are discussed in the paper in greater detail. In order to study grain yield, grain moisture, root and stalk lodging, and resistance to pests and diseases, field trials using a RCB design with four replicates were conducted in six locations in 2009 and five locations in 2010. The results were presented in the form of GGE biplots in order to rank hybrids relative to the standard while taking into account the genotype x environment interaction and to identify the highest-yielding genotypes in different environments. It was determined that the new NS hybrids had higher grain yield than the standard by 0.883 to 1.720 tha^-1, lower grain moisture by 0.85 to 2.54%, better tolerance to root and stalk lodging, and pest and disease resistance on a par to the standard. The study identified so-called ideal locations for particular hybrids, which may be of use when determining which areas the hybrids are best suited for.

Key words: genotype x environment interaction, GGE biplot analysis. grain yield, maize hybrids

Due to the low biological value of proteins of common maize, it was reinitiated breeding for high protein quality maize (HQPM) using three genetic systems, namely: opaque-2 gene, endosperm modifier genes and enhancer genes, which are increasing lysine and tryptophan content in opaque-2 background In order to alleviate effect of abiotic and biotic stress factors, the genotypes with tolerance to those factors were included. Genetic resources originating from North, Central and South America, then West, Central and Southern Africa and gene bank of Maize Research Institute “Zemun Polje” were used. Combining breeding approaches in selection of genetic resources, field plot techniques and laboratory analysis, it was created large number of early QPM varieties, inbred lines and hybrids with modified endosperm and high yield potential under poor and good growing conditions. Created lines exhibited high combining ability in conventional and non-conventional hybrids. Yield trials showed that QPM hybrids are competing with commercial hybrids of common maize.

Abstract

Golparvar A.R. (2012): Heritability and mode of gene action determination for grain filling rate and relative water content in hexaploid wheat. - Genetika, Vol 44, No. 1, 25 -32.

Mode of gene action, heritability and determination of the effective breeding strategy for improvement of physiological and traits specifically in drought stress conditions is very important. Therefore, this study was conducted by using two drought susceptible and tolerant wheat cultivars. Cultivars Sakha8 (tolerant) and Pishtaz (susceptible) as parents along with F₁, F₂, BC₁ and BC₂generations were sown in a randomized complete block design with three replications in drought stress conditions. Results of analysis of variance indicated significant difference between generations as well as degree of dominance revealed over-dominance for the both traits. Fitting simple additive-dominance model designated that this model was not able to account for changes of traits relative water content and mean of grain filling rate. It was revealed that m-d-h-i-j model for relative water content and m-d-h-i model for mean of grain filling rate are the best models. Estimation of heritability and mode of gene action indicated that selection for improvement of traits studied in stress condition and specifically in early generations have medium genetic gain. In conclusion, grain filling rate is better than relative water content as indirect selection criteria to improve plant grain yield in drought stress condition.

Key words: Bread wheat, generation mean analysis, drought tolerance, gene action

NS soybean cultivars were assessed for variability of and correlations between yield components and the effect of genotype -environment interaction on yield, yield component and morphological characteristics. Experiments were carried out at Rimski Šančevi experiment field in 2009 and 2010. The following characteristics were evaluated: plant height (cm), height of first pod (cm), 1000-grain weight (g), grain yield (kg/ha) and the combined content of oil and protein in grain (%). Combined contents of oil and protein in grain soybean were determined by a non-destructive method of near infrared spectroscopy on PERTEN DA 7000 (NIR/VIS Spectrophotometer).

The studied characteristics varied significantly depending on genotype and year. The highest yield of 5273 kg/ha was obtained in 2009 with the genotype Victoria. Highest 1000-grain weights, 2009-2010, were achieved with the genotypes Valjevka and Victoria (149.27 g and 147.23 g). Maximum heights of first pod (19.40 cm) were recorded for the genotype Victoria, 2009-2010. Highest protein contents were obtained with the genotypes Valjevka and Victoria, 2009-2010, were and highest oil contents (21.73%) with the genotype Tea. Protein content was positively significantly correlated with 1000-grain weight and negatively significantly correlated with oil content, and negatively correlated with yield and the height of first pod. Oil content was positively correlated with the height of first pod. Thousand-grain weight was negatively highly significantly correlated with oil content in grain and negatively significantly correlated the height of first pod.

The results of this study should facilitate further soybean breeding for improved seed yield and protein and oil contents.

In this experiment, colonies of six regional populations from the territory of the Republic of Serbia were included, and two generations (maternal colonies and their offspring) were observed. In two inspections (fall and spring), production traits and temperament were observed. Daughter queen bees mated in uncontrolled conditions (free-mating) in order to determine heritability of production traits in terms of practical beekeeping. The heritability coefficients (h²) for production traits calculated. It was found that the honey yield was mostly determined by genetic, but environmental conditions also had significant influence. Heritability for honey yield (h²) ranged from 72.72% (Rasina population) to 81.04% (Banat population). Colony strength was very dependent on external factors, but also from the very population. When it comes to food supply (honey and pollen), in the inspections, large differences in the heritability coefficient were determined, which is explained by the interaction of genetic factors (the foraging instinct) and environmental factors (honey flora and climatic conditions during foraging) and the influence of beekeepers (feeding, etc.).

Abstract

Cervenski J., J. Gvozdanovic-Varga, and S.Glogovac (2012): Variance components and correlations of agronomic traits among cabbage (Brassica oleracea var. capitata L.) maturity groups. - Genetika, Vol 44, No. 1, 55 -68.

In this paper we studied the variability and correlation of cabbage traits in different maturity groups. The study included early spring cabbages (planted in early spring, harvested in early summer) and autumn cabbages (planted in mid-summer, harvested in late autumn). Using coefficients of variation and correlation coefficients, we analyzed 17 cabbage traits in 35 commercially grown cultivars, F1 hybrids, and experimental F1 hybrids. The traits were analyzed separately for each maturity group. In the early cabbages, the coefficients of variation ranged from 4.8 to 44.2%. The calculated correlation coefficients differed between the two maturity groups. The early cabbages had 26 significant positive correlations. The positive correlations calculated among different traits of early cabbages defined this group fully and made it distinct from the late-maturing genotypes. Plant height and rosette diameter in the early genotypes were highly positively correlated with rosette weight, whole plant weight, head weight, usable portion of head, head height, and head diameter. Plant height and rosette diameter participate in the formation of active photosynthetic area in early cabbages. Rosette width in these genotypes provides a greater influx of light and heat, which results in greater head weight. Also, in early cabbages that have greater plant height, the leaf rosette will not lie on the cold surface of the ground in the spring. The activity of the cabbage plant is thus more focused towards the formation of larger head weight. Head volume in the late genotypes was highly positively correlated with rosette diameter, whole plant weight, head weight, usable portion of head, inner stem length, and head height. In late cabbages plant activity is directed towards the formation of head volume due to the longer duration of the growth period, larger leaves, and differences in climatic conditions.

Key words: cabbages, correlations, head, maturity, variability.

Herein, we present the combined S1-HS-RRS method using inbred testers (S1-TC-RRS) as a long-term maize breeding program, which increases the frequency of favorable alleles and maintains genetic variability in two genetically opposite populations. The method improves two different genetic sources simultaneously, where S1 families, developed by selfing phenotypically superior plants from both breeding populations are crossed with opposite inbred testers for specific combining ability selection, accompanied by selection of S1 families per se. A certain percentage of the evaluated S1 families is used for the next TC-RRS selection cycle. Maternal haploids from the selected S1 lines of each cycle of S1-TC-RRS can serve to produce elite 100% homozygous inbred lines (dihaploids) in a short time, which decreases the time and expenses of the selection cycle and influence the efficiency of seed production, as well as, variety protection rights. This elite lines than can be converted to cms versions (paternal haploids), for the seed production, which lowers the costs of it.

Abstract

Dimitrijević M., S. Petrović, and B. Banjac (2012): Wheat breeding in abiotic stress conditions of solonetz. - Genetika, Vol 44, No. 1, 91 - 100.

The complex stress environment at locality Kumane (Banat) primarily is caused by alkaline soil of solonetz type, but includes the other sources of wheat variability, water-logging and occasional extreme temperatures, as well. In order to obtain wheat varieties that could fulfill the requirement of enhanced tolerance to abiotic stress conditions of alkaline soil a set of wheat varieties was examined in parallel trials in Kumane (solonetz), and at Rimski Šančevi on chernzem (black soil). The multiyear results helped to select usable wheat genetic material among the existing varietal genetic variability. That variability was used as parents in in situ established crosses. The results in segregating F₂ offspring surpassed the average parental values for examined traits – plant height, grain number and grain weight per spike. Hence, selecting desirable genetic variability in novel variability through years could lead to wheat plant ideotype capable to bring forth a economically justified yield.

Abstract

Babić M., V. Babić, S. Prodanović, M. Filipović, and V. Anđelković (2012): Comparison of morphological and molecular genetic distances of maize inbreds - Genetika, Vol 44, No. 1, 119-128.

Due to an unknown mechanism of genetic control and great environmental effects in the process of trait expression, morphological markers are often considered unreliable indicators of genetic relationships. Morphological characterisation of 19 maize inbreds was done according to the UPOV descriptor, while molecular characterisation was performed with RAPD markers. Based on the estimation of phenotypes according to the UPOV descriptor, the squared Euclidean distance was calculated and then, on the basis of this distance, a morphological similarity matrix was formed. Jaccard similarity coefficients were calculated on the basis of presence-absence of bands on gels in the RAPD analysis. When data were standardised, the comparison between morphological and genetic similarity of observed maize inbreds was done. The correlations varied from 0.47 (inbred L 217) to 0.76 (inbred L 86). The average value of correlations for all studied inbreds amounted to 0.64. Furthermore, the results of the cluster analysis for both markers, molecular and morphological, had high concordance with pedigree data. Environmental effects were decreased in morphological markers (according to the UPOV descriptor) by rescaling a measurement scale from a scale to an ordinal level of measurement and in such a way results of morphological markers approached results of molecular markers in the estimation of the genetic distance (GD) of maize inbred lines.

Abstract

Lukic M., S. Maric, I. Glišić, and N. Miloševic (2012): Variability of properties of promising apple selections of the ‘Jonathan’ group. Genetika, Vol 44, No. 1, 129 - 138.

Apple (Malus ´ domestica Borkh.) is economically the most important species of genus Malus Miller. Developing new apple genotypes is carried out on a large scale in many scientific institutes throughout the world. ‘Jonathan’ is one of four cultivars which have been used as the most frequent progenitors in apple breeding programmes worldwide. The paper presents six promising apple selections bred at Fruit Research Institute, and ‘Jonathan’ as the parental cultivar. The assessed selections derived from the crosses ‘Jonathan’ ´ ‘Idared’ (J/3/60 and J/2/53), [‘Jonathan’ ´ J/54/53/59] ´ J/27/127/62 (J/4/106) and ‘Jonathan’ ´ J/54/53/59 (J/1/55, J/1/71 and J/1/15). Major phenological properties (flowering phenophase and harvest time), cropping and pomological properties (morphometrical and chemical characteristics of fruits) were assessed. The highest fruit weight (J/2/53; 188.4 g) and yield per unit area (J/3/60; 34 t ha^-1) were reported in selections derived from the cross ‘Jonathan’ ´ ‘Idared’. Selections raised from a cross between ‘Jonathan’ and J/54/53/59 have high quality fruits. The highest soluble solids content was found in J/1/55 (15.3%), while the highest total sugars and acids content was evidenced in J/1/71 (9.61%; 1.46%, respectively).

Paper presents results for length of vegetation period as factor in common oak’s (Quercus robur L.) phenological variability. Trees in two common oaks populations on two locations in area of Belgrade were researched. Average length of vegetation period on site Ada Ciganlija is 166 days, while in location Bojčinska šuma is 179 days. Regarding that populations are in similar environmental and habitual conditions, differences in results should be treated as consequence of common oaks intra-specific variability and genetic structure of population. Significant differences in three consecutive years of observation are confirmed.

Key words: Quercus robur L., vegetation period, population and individual variability

University of Belgrade, Faculty of Agriculture, Belgrade, Serbia

Abstract

Bogdanovic V. (2012): Source of variation and heritability of directly measured traits in performance testing of Simmental bulls- Genetika, Vol 44, No. 1, 153-162.

In order to study the variability and heritability of directly measured traits (growth and body development traits) in performance test of Simmental bulls the data on 371 bulls born and tested over the period of 13 years were used in the analysis. The data were analysed in order to estimate year and month of calving, herd of origin and group in test effect as well as error components. The components of variance were obtained using restricted maximum likelihood (REML) methodology applied to sire model. The year and month of birth had different effect on the variability of the growth traits, while the herd of origin and the test group manifested a consistent, highly significant effect on those growth traits which they could have an effect on. On the other hand, all the body development traits were under a constant and highly significant effect manifested by the year of calving, while the month of calving manifested its effect, during test, at different levels of statistical significance. A decreased effect of herd of origin on almost all body dimensions from the start until the end of performance test was universally observed. Heritability estimates for pre-test ADG, in-test and lifetime ADG were 0.27, 0.39 and 0.29, respectively. Heritability estimates for body weights were 0.23, 0.25, and 0.30 for birth weight, test-on weight, and test-off weight, respectively. Heritability estimates for test-off height at withers, circumference of chest, depth of chest and body length were 0.43, 0.30, 0.33 and 0.29.

Key words: bulls, performance test, growth traits, body development, heritability

- Genetika, Vol 44, No. 1,163 -176.

Species of the genus Fusarium are characterised by the exceptional intraspecies and interspecies variability in respect to morphological, physiological and genetic properties. Intraspecies and interspecies diversity of Fusarium verticillioides and Fusarium proliferatum isolates in the production of fumonisin B₁ according to their origin from maize and wheat grains was studied. Fumonisin B₁ production potential of investigated 42 isolates was assessed by HPTLC and ELISA method. All 22 and 20 investigated F. verticillioides and F. proliferatum isolates, respectively, had the ability to produce fumonisin B₁ toxin. Fumonisin B ₁ production potential of F. verticillioides and F. proliferatum varied from 88.60 ppmto 1,300.60 ppmand from 2.37 ppmto 1,246.00 ppm,respectively. According to Mann-Whitnev U test, there were no significant differences between the fumonisin B₁ production mean values of isolates of F. verticillioides originated from maize and wheat (628.13 ppmand 696.38 ppm, respectively), as well as, fumonisin B₁production mean values of F. proliferatum isolates (212.32 ppm and 158.07 ppm, respectively). Variability coefficient values indicated that fumonisin B₁ production potential variability was more expressed in maize than wheat originated isolates for both species.

Abstract

Dadashpour A. (2012): Application of sorting dependent criterias in determination of volume and area bruising of “Golab-kohanz” apple in Iran - Genetika, Vol 44, No. 1, 177 - 187.

Apple fruits are subjected to different loading damage from harvesting to supermarket shelf. Bruising has been attracted many researchers as one of the most important damage criteria. In this research, the effects of some factors such as counter-face material, drop height and linear velocity of apples (conveyor speed) were investigated. Influence of these factors on bruising of “Golab-Kohanz” variety was analyzed by a Completely Randomized Design (CRD) with factorial test at three levels of drop height (10, 20 and 30 cm), conveyor speed (0.05, 0.1 and 0.15 ms^-1) and four counter-face materials (wood, steel, plastic and cardboard). Tests were conducted at three replications with 108 treatments. Analysis of variance results showed that the effects of drop height and counter-face material on bruising area at 1% level was significant while bruising volume only affected by contact surface material (P<0.01). Mean comparison test indicated that there was no significant difference among levels of conveyor speed on the area and volume bruising. Also, there was no significant difference among levels of drop height on volume bruising while it was significant on the area bruising. Steel and wooden material had no significant effect on the area and volume bruising but their differences with plastic and cardboard were significant. Therefore, drop height and counter-face material must be considered in designing the apple processing systems.

Key words: bruising, counter-face material, drop height, Golab-Kohanz.

Abstract

Oro V. and V. Oro Radovanović (2012): Molecular characterization of PCN populations from Serbia - Genetika, Vol 44, No. 1,189 – 200.

The morphology of potato cyst nematodes (PCN) was until recently almost the only way to identify these quarantine organisms. In the last two decades, molecular analyses contributed to faster and more efficient identification of two Globodera species (Globodera pallida and G. rostochiensis) and allowed insight into the genetic structure of those parts that were practically inaccessible by morphological studies. Molecular characterization was performed in ITS1-5.8S-ITS2 region. The comparison was made with sequences of different foreign PCN populations via NCBI GenBank database. The results of molecular studies showed similarities and differences between local and foreign PCN populations in the part of genome that was studied.

Abstract

Kovacevic D. and B. Lazic (2012): Modern trends in the development of agriculture and demands on plant breeding and soil management - Genetika, Vol 44, No. 1, 201 -216.

Agriculture is usually developed as much and just society where there is a branch of the economy. Today, there are different directions from industry agriculture to many concepts based on ecological principles. Future of agriculture development in the XXI century will imply sustainable agriculture as the alternative to the industrial agriculture.

Conventional agriculture as an intensive one has a duty to ensure maximum production in terms of quantity and quality with the low cost. For this purpose we have many cultural practices, sometimes in addition to the expected positive but sometimes with many unexpected long-term negative effects in agroecosystems.

Organic agriculture is one of the most interesting current trends in agriculture completely based on strong ecological principles and the absence of application of agrochemicals (pesticides, fertilizers, hormones), GMO, etc. Organic agriculture is a holistic way of farming: besides production of goods of high quality (better flavor, high content dry matter, vitamins, antioxidants); conservation of the natural resources (soil, water) and richness of biodiversity.

Key words: biodiversity, biodynamic agriculture, breeding challenges, conventional (industrial) agriculture, organic farming, sustainable development
