GENETIC ANALYSIS FOR EARLINESS IN SAFFLOWER (CARTHAMUS TINCTORIUS L.)

Abstract

Gupta, R.K. and S.P. Singh (1988): Genetic analysis for earliness in safflower (Cartlwmus tinctorius L.). - Genetika, Vol. 20, No. 3, 219-227.

The extent of the nature and magnitude of genetic variance and combining ability were studied in 10 parent diallels in safflower (Cartfiamus tinctorius L.) for days to flower and days to maturity. Graphical and component analysis revealed partial dominance for days to flower and over dominance to complete dominance for days to maturity in F₁ and F₂. Combining ability analysis indicated the predominance of additive gene action (σ²g). Heritability was high for both the characters. Parent 'culture 1' possess maximum recessive genes and was also found to be the best general combiner for both traits. The crosses 'S 59-2-1' x 'U-C.l' and 'E-C 33963' x E.G. 27509 were the best cross combinations with additive x additive type gene interaction. Consequent upon the present findings, a breeding plant to develop early maturity genotypes was discussed.

Variation of the root parameters (total root area, length and dry weight) in young plants has been investigated in five wheat cultivars and five F₁ hybrids. The mode of inheritance of root parameters in F₁ was mostly dominant or heterosis occured. Most of the phenotypic variance for root length and dry weight was due to genetic differences between genotypes and F₁ hybrids.

Abstract

Pejčinović M. (1988): Cytotypes of Allium roseum L. in Yugoslav Mediterranean. - Genetika, Vol. 20, No. 3, 235-245.

The species Allium roseum L. has been cytotaxonomically investigated in 17 populations which originate in the Yugoslav Mediterranean. Two ploidy levels were found: A. roseum var. roseum with 2n = 32 and A. roseum var. bulbilliferum Vis. with 2n = 40 chromosomes. The first - a tetraploid form - was examined in detail in seven populations, while the second - a pentaploid - was studied in ten populations. Their karyotypes have been described and their karyograms prepared. Certain meiotic irregularities are described. General karyotypic variations are mostly related to taxonomic categories.

Females of five crosses between triticale and wheat were evaluated for their mean performance and genetic parameters with regard to 15 morphological and quantitative traits. The magnitude of variance for grains per spike was highly significant in all the crosses but extraordinary high genetic advance (GA) and heritability (h²) was observed in the families of the crosses Rahum x HS 74 and Rahum x Sonalika, which were also found to have high GA for 100-grain weight. The families of the crosses viz. TL 68 x HS 74 and Rahum x Sonalika exhibited high mean values and an unusual and extraordinary high GA of 108.61% and 105.84%, respectively, for grain yield per plant, indicating the genetic potentiality of these crosses for improvement in grain yield. Therefore, the present study clearly indicates that selection would be quaite effective in isolating short secondary triticales having high sink and source potential, early maturity, well filled grains and high yield, following hybridization between triticale and wheat.

Abstract

Lazic-Jančić V., M. Denić and Lj. Topisirović (1988): Comparison of free and membrane bound ribosomal proteins of normal and opaque-2 mutant of maize. - Genetika, Vol. 20, No. 3. 255-267.

Proteins of the cytoplasmic ribosomes isolated from free and membrane bound polysomes from the endosperm of normal (W64A) and opaque-2 mutant (W64Ao₂) were compared by two-dimensional poly-acrylamide gel electrophoresis (2D-PAGE) and by amino acid analysis. The monosomes of both genotypes and from both classes gave similar patterns with 58 basic proteins. Gel electrophoresis revealed at least one difference in protein pattern of the two polysome classes, namely the reduced mobility of protein 31 of bound polysomes. As a consequence, the sum of basic amino acids from bound polysomes decreased in both normal and mutant genotypes. Between the genotypes, differences were found between proteins from membrane bound polysomes. In total mutant ribosomal proteins of membrane bound polysomes the sum of basic amino acids decreased, but asx and glx were higher than in the normal genotype. This is in agreement with the change observed in the mobility of protein 50.

The amino acid composition of polypeptides 3+4, 20, 25, 27, 30, 31, 49 and 50 from bound polysomes of the two genotypes were fairly similar, except differences in amounts of lys, ser and glx.

In this work the coeffect of heavy metals on the duration of preadult development in a natural population of Drosophila melanogaster from Titova Mitrovica was studied. The analyses comprised the 2^nd pair of chromosomes which was isolated and transferee! either in the homo- (+'/+') or heterozygous (+'/+") state. In the experiments performed under laboratory conditions different solutions of two or three heavy metals, were fed to individuals.

Our results demonstrate that the solutions of the heavy metals applied led to prominent effects by prolonging of the total duration of preadult development at the homozygous and heterozygous progeny in relation to the untreated group. The largest prolongation of the duration of preadult development was achieved when a com bination of 0.05% lead acetate and 0.01% cadmium chloride was applied.

On the basis of our results it could be assumed that the synergistic effect of heavy metals led to the appearance of different mutations on chromosomes controlling the duration of preadult development in Drosophila

The objective of this investigation was to study general (GCA) and specific (SCA) combining ability for grain yield of maize inbred lines, selected from different cycles of BSSS synthetic in diallel crosses with other unrelated lines.

Inbred lines obtained from later cycles of recurrent selection were found to have better GCA and SCA for grain yield than inbred lines from earlier cycles.

Abstract

Tucić N., M. Milošević, D. Bejaković, D. Cvetković, D. Milanović and I. Petković (1988): Effects of differential extinction and deme size on the rate of population increase in bean weevil (Acanthoscelides obtectusSAY). - Genetika, Vol. 20, No. 3, 299-311.

In this paper we present the results of an experimental study of the effects of local deme size on the phenotypic and genetic differentiation of denies for traits affecting the rate of population increase. Artificial group selection for both increased and decreased populational productivity was conducted on bean weevil (Acanthoscelides obtectus) populations. Group selection, which in our experiment took place strictly through the extinction process, was ineffective. We conclude that nonrandom extinction can become group selection if there is a differential proliferation of the surviving populations. We found, however, that the rate of phenotypic differentiation of an array of demes is curvilinear over time and inversely proportional to the deme size. Our results suggest that the random extinction combined with the absence of differential proliferation decreases the total amount of among-deme variances. The magnitude of the heritable component of the among-deme variation appears to be largely independent of the size of colonizing propagates. These findings are discussed in relation to group selection theory.

Electrophoretic patterns of the nine enzymes -belonging to the dehydrogenases have been studied in liver and kidney samples of the roe deer from central Serbia (in the eastern part of Yugoslavia). Since electrophoretic data for this species are almost non-existent, these should serve as u. bases for future population genetic an4 systematic studies.

Abstract

Savić D. and Lj. Topisirović (1988): Bacterial transposons - Genetika, Vol. 20, No. 3, 323-338.

A brief review of transposing elements in bacteria is presented. The main body of the text is dedicated to the molecular mechanisms of transpositions as a necessary prerequisite for understanding the rearrangements following transpositions. Attention is also paid to the classification of movable elements, to their structures, and to the regulatory mechanisms which govern their movements. In the last part attention is focused on the question of the evolutionary "raison d'etre" of these elements. Conflicting theories on transposable elements as genetic entities which provide adaptive benefit to their carriers, and transposons as genetic parasites, are given in some detail.
