Galović Vladisava, Snežana Mladnović Drinić, Julijana Navalušić, Marija ZlokolIca (2006): Characterization methods and fingerprinting of agronomicaly important crop species – Genetika, Vol. 38, No. 2, 83 -96

Continued usage of morphological data to describe agronomically important genotypes indicates that those data retain popularity as descriptors of plant species.However, the need is arising for their more detailed description by laboratory-based biochemical and molecular methods. The standardization of those techniques has been achieved by ISTA and UPOV through DUS testing that is the basis of the system of protection of Plant Breeders Rights. Not only by morphological characterization but also by combining morphological, biochemical and molecular aspects in identification and description of agronomically important genotypes, it is possible to reveal their unique genetic profiles e.g. fingerprints.

In this review we summerised the techniques that proved to be successfuly applied in biochemical and molecular characterisation of agronomicaly important genotypes. Obtaining their unique genetic profiles due to application of those methods, it is now possible to precisely characterize them with most certainty and reproducibility.

Abstract

Salceda V. and J.Espinoza-Velazquez. (2006): Micro-geographic variation of inversions in natural populations of Drosophila pseudoobscura – Genetika. Vol. 38. No. 2. 97-106.

Chromosomal polymorphism for the third chromosome in Drosophila pseudoobscura has been widely studied for genetic variation in different environments or locations far apart. However, there is less information regarding sites geographically near one another. Targeting on possible micro-geographic variation in the species, a serial study was done on 12 Mexican populations grouped in four regions, including locations in Durango (DU), the border area of Guanajuato-San Luis Potosí states (GP), Chiapas (CH) and Saltillo (SA). Flies were trapped in their natural habitats using fermenting bananas as bait. They were individually cultivated in the laboratory for larvae production. In a given population sample several flies were cultivated together but only one larva per culture provided salivary tissue to observe polytene chromosomes. Gene arrangements or inversions were identified and frequencies were calculated. A total of 767 third chromosomes were studied and 11 different inversions detected. The type and relative frequencies of the arrangements varied among regions. From the 11 inversions observed, 10 were found in Durango, five in Guanajuato-San Luis Potosí and Chiapas, and eight in Saltillo. The inversion frequencies in the Durango locations varied in four cases, but only one in Chiapas, three cases in Guanajuato-San Luis Potosí, and five in Saltillo. It was also observed that there were geographical gradients for inversions within regions as follows: four arrangements in Saltillo and Durango, three in Guanajuato-San Luis Potosí and one in Chiapas. Moreover, all four regions studied showed evidences for micro-geographical variation. Nevertheless, more studies are needed to elucidate the relevance of the inversion frequencies changes in neighboring populations and also any seasonal-annual frequencies observed in the locations studied here.

Abstract

Paunović A., D. Knežević. and M. Madić (2006): Genotype variations in grain yield of spring barley depending on sowing density – Genetika, Vol. 38, No. 2, 107 - 114.

A three-year study was carried out for grain yield in five cultivars of the spring brewer's barley at the Small Grains Research Centre of in Kragujevac from 1996 to 1998. The effect of three sowing densities on the number of spikes, grain number per spike and grain yield was studied for each cultivar. Research results have shown that the cultivars displayed a highly significant effect on the grain number per spike and grain yield. It has also been noticed that, in the course of every research year, sowing density induced increases in spike number and grain yield. In contrast, the higher sowing density brought about a decrease in the grain number per spike.

Key words: spring barley, genotypes, sowing density, yield.

Abstract

Gorjanović B,. M. Kraljević-Balalić. (2006): Correlations among yield components in durum wheat – Genetika. Vol. 38. No. 2., 115 -120.

The main reason that makes breeding for the main yield components difficult is that they are in negative correlation with each other. Numerous researchers have studied relations between yield and different yield components in order to find dependable selection criteria. The goal of this paper is to estimate the variability and correlations between yield components. The experiment was conducted on twelve durum wheat genotypes. Plant height was in both years positively correlated with number of spikelets per spike and negatively correlated with spike length. grain weight per spike. number of grains per spike and harvest index. Spike length was positively correlated with grain weight per spike and number of grains per spike. in both years and with harvest index only in the first year. while it was negatively correlated with number of spikelets per spike in the first year. Number of spikelets was in negative correlations with grain weight per spike and number of grains per spike in the first year. and with harvest index in both years of investigations. Grain weight per spike was positively correlated with number of grain per spike and harvest index in both years. Number of grains per spike was in positive correlation with harvest index in both years of investigations.

Key words: durum wheat, yield components, variability, correlation.

New directions in animal husbandry demand raising of animal kinds that are adjusted to intensive way of breeding. In order to accomplish these demands, beside known methods in selection, Cytogenetic control of existing genotypes is needed that has been carried through ten year examination on pig, cattle and stud farms in Vojvodina. Chromosome aberration of numeric polyploidy and aneuploidy but also structural translocation, deletion, duplication, inversion, ring, break and other segregations were discovered. Numeric and structural changes on animal karyotype influenced on reproduction disturbance, phenotype expression, as well as selection program and stability of genofond. Different aspects of reproductive disturbance were noted like for example: small litter, embryo mortality, frequent repeated breeding, abortion, stillbirth and mummified embryo, offspring with anomalities, different kinds of sterility, Analyses of the results obtained from monitoring the herd book and making genealogy show on existence of chromosomepathy on our farms. The aim of this work is to inform scientists and experts with the fact that these changes are spreading, especially through among the breeding animals. Therefore genetic control and timely exclusion of chromosome aberration is necessary.

Abstract

Rodeva V., S.Grozeva, V.Todorova. (2006): In vitro answer of Bulgarian pepper /Capsicum annuum L./ varieties – Genetika. Vol. 38. No. 2., 129 -136.

Callusogenesis and regeneration ability of cotyledon and hypocotyl explants from three Bulgarian pepper varieties in MS basal medium supplemented with 1-3mg/l BAP. 1.0mg/l IAA and 0.5mg/l GA3 was studied. In the different variants of culture medium was registered high level of callusogenesis and organogenesis in both type of explants from the all varieties. The highest percentage of plant-regenerants is established in cotyledon explants (from 3.3 to 18.3) in variant 3 of the culture medium containing 3mg/l BA. In the process of micropropagation by stem explants of the same studied pepper varieties the addition of the vitamins C. B₁₂. Casein hydrolysate and Ferulic acid had a stimulation effect on the plant growth in height and rooting. In result of anther cultivation from three pepper varieties and four breeding lines the highest percentage of embryo structure formation was registered in varieties Albena and Strjama (12.0 and 13.8 respectively). The Bulgarian peppers are recalcitrant and their in vitro answer is different depending from the explant type. genotype and the culture media composition.

Abstract

Kondić-Šipka Ankica, N.Hristov, B.Kobiljski (2006): In vitro screening for low temperature tolerance of wheat genotypes – Genetika. Vol. 38. No. 2., 137 -144.

Low temperature (LT) tolerance of 12 wheat (T. aestivum L.) genotypes was investigated in an in vitro zygotic embryo culture. Isolated embryos were grown on a modified MS medium for two months. Calluses were prepared by gradual decrease of temperatures (17˚C-7 days, 5˚C-7 days, -5˚C-1 day, -10˚C-1 day) and then exposed to LT treatments (-15˚C, 24 h and 48 h). After LT treatments, calluses were acclimated by gradual increase of temperatures and grown for another month. Based on the differences in callus fresh weight between the control group and calluses exposed to the LT treatments, levels of LT tolerance of wheat genotypes were determined.

The results have shown that out of the 12 wheat cultivars, 6 had a high level of LT tolerance, 5 had a medium and only one spring cultivar (Venera) had a low level of LT tolerance. These results were compared with the results of the standard in situ test in a cold chamber. Only partial disagreement of results was determined in two cultivars with the medium level of LT tolerance (NSR-2 and Balkan). It can be concluded that the in vitro test can be successfully used for the separation of genotypes with high and low levels of LT tolerance, but for more precise separation within the medium level of LT tolerance, the test should be improved.

Key words: low temperatures, in vitro test, tolerance, wheat

The samples from field experiment on five clones of white willow (Salix alba L.) in the adult phase, was investigated as follows: net photosynthesis and dark respiration, content of photosynthetic pigments (chlorophylls a,b and carotenoids), number and size of stomata and elements of growth (tree diameters and heights). The aim of the research is to determine if there are any relations between these physiological characters and the elements of growth, i.e. if any of them can be utilized in the early selection for growth vigor. The results show that all the characters are characterized by low coefficients of variation, statistically highly significant differences and high coefficients of heritability in a broad sense. As for the net of photosynthesis, the number of stomata on the adaxial and abaxial sides of the leaf are in high correlation with the elements of growth, which indicates that they can be used in the early selection for growth vigor.

Androgenous and regeneration abilities of 8 heterozygous wheat (Triticum aestivum L.) genotypes were analyzed in anther culture. Cytological characteristics of green regenerants were also analyzed. Significant differences were found among the genotypes in their androgenous and regeneration abilities. The average androgenous capacity of all genotypes was 4.4% ranging from 0.7% (Prima/Hueguen) to 11.0% (NS173-98/NS164-98). The average callus yield was 8.7%. The genotype Banks/F53-70 produced the higest number of green plants (33 green plants), while the genotype Banks/Pobeda showed no green plant regeneration ability. The frequency of albino plants ranged between 0% (Banks/Rodna) and 5.3% (Anastasija/Radika). A total of 61 green and 61 albino plants were regenerated.

The results of cytological analysis showed that, from the total number of regenerated green plants, 40.9% were haploids and 59.1% were spontaneous double haploids.

Key words: androgenuos ability, anther culture, cytological characteristics, Triticum aestivum L.

Phenotype, chromosomes pairing and pollen vitality were compared between parental populations and F₁ hybrids of interspecific cross between Helianthus annuus L. and cultivated sunflower. The investigation of the simple sequence repeats (SSR) polymorphism was also used to test the hybrid nature of F₁ populations.

The phenotypic traits of F₁ hybrid plants were either closer to the wild species or intermediate. Irregular chromosome pairing was found in only 0 to 10% of meiocytes in the meiosis of F₁hybrid plants. Interspecific crosses were confirmed with SSR markers in all hybrid combinations. Alleles that were not present in parental DNA were frequently observed in F₁hybrids. That is additional evidence that those hybrid combinations were not produced by self-fertilization.

The results suggest that SSR markers can be efficiently used for the F₁ hybrid characterization in crosses between closely related species, in which, the changes of phenotype, meiosis and pollen vitality are not always significant.

In the present study, an additional approach was used to evaluate the potential effects of the industrial development on natural population of the common plantain (Plantago major L.), previously estimated using s_i² as an index of fluctuation asymmetry (FA) together with the coefficient of variation (CV). In this study, directional asymmetry (DA), a form of asymmetry in bilaterally symmetric traits, was used in order to estimate its rule as a potential indicator of developmental instability in leaf traits. Obtained results shows significantly higher DA values for the vein distances within a leaf (VD) on environmentally stressed area than in the control site. Reporting significantly higher values of DA for VD on the environmentally stressed sample and a positive relationship between FA and CV values obtained for the same trait within the same site, in a previous study, the study corroborates the potential of DA as an indicator of developmental perturbations.

Key words: asymmetry, coefficient of variation, directional, fluctuating, Plantago major L.
