Abstract

Šurlan, G. and Đ. Nikolić (1990): Correlation and paht analysis in soybean. - Genetika, Vol. 22, No. 3, 165-172.

The main objectives of our study were: (i) to determine genetic and phenotypic correlation coefficients among several agronomic and biochemical characters in twelve soybean varieties, and (ii) to analyze their interrelationships through path coefficient analysis. Genetic path coefficient analysis indicated a significant effect of seed weight, seeds per plant and pod number per plant on yield. At the same time, the indirect effect of pod number per plant via seeds per plant was higher than the direct effect. Phenotypic path coefficient analysis indicated pod number per plant to be less important than seeds per plant and seed weight. In contrast, protein and oil content had a significant direct negative effect on yield.

COMBINING ABILITY IN RELATION TO BREEDING SYSTEMS IN SAFFLOWER (CATHAMUS TINCTORIUS L.)

Abstract

Gupta, R.K. and S.P. Singh (1990): Combining ability in relation to breeding systems in safflower (Carthamus tinctorim L.). - Genetika, Vol. 22, No. 3, 173-182.

Combining ability of oil content, seed yield and other 6 component characters was studied in a 10 parents diallel cross of diverse origin in F₁ and F₂. The variances due to gca and sca were highly significant for all the characters. The estimated components of variances revealed that non-additive gene action was important for all the characters in both generations except plant height. On the basis of rank index of per-se and gca effects, 3 Indian i.e. 'I.C. 11842', 'Local' and 'Culture' and one exotic viz. 'E.C. 33963' of the Iran cultivars were the best combiners for seed yield, oil content and most of the component traits. Performance of parents was closely associated with their gca effects and rank correlation was highly significant. All the crosses showing high sca effects involved all 3 type of gene interaction i.e. additive x additive, additive x dominance and dominance x dominance. The crosses Local x 'S_{59_2—l}' and E.C.33963' x 'E.C.27249' in F₁ and 'Local' x 'I.C. 11842' in F₁ and F₂ revealed additive x additive gene interaction and were promising for oil content and seed yield. Present findings suggest breeding methods such as population improvement of progenies derived from bi-parental mating followed by recurrent selection for the improvement of seed yield and oil content.

Abstract

Vapa, Lj. and P. Boža (1990): Analysis of quantitative characters within natural populations of Haynaldia villosa. - Geneti-ka, Vol. 22, No. 3, 183-190.

The variability of quantitative characters (spike length, number of spikelets per spike, number of grains per spike and grain length) within populations of Haynaldia villosa obtained from different localities is discussed. No significant difference between mean values of the examined characters were observed in populations obtained from either Kotor or Smederevo localities, while with other populations the means were significantly different for a majority of the examined characters.

THE EFFECT OF INHIBITOR GENE OF INHERITANCE OF HYURID NECROSIS IN COMMON WHEAT CROSSES

Abstract

Dimitrijević, M. (1990): The effect of inhibitor gene on inheritance of hybrid necrosis in common wheat crosses. - Genetika, Vol. 22, No. 3, 195-204.

The inheritance of hybrid necrosis in common wheat was studied in progenies of nine cross combinations, involving Yugoslav high-yielding varieties of wheat as parents. Segregation ratios of 9:55, 1:15 and 19:45 (necrotic : normal) were found in the F₂ generations. These ratios indicated the effect of an inhibitor gene on the complementary major genes present in wheat. Besides the mutual effects of the three major genes (Nei, Ne₂ nad I), a dosage effect was established. The degree of hybrid necrosis varied depending on the number of dominant genes present in a plant. The influence of the genetic background was also ascertained.

Abstract

Stupar, M. and K. Borojević (1990): Gene effect for seed protein content in wheat. - Genetika, Vol. 22, No. 3, 213-220.

Diallel crosses between eight wheat genotypes, including reciprocals, were made in order to evaluate the mode of gene action and genetic variance of seed protein content. Out of these eight genotypes, three were mutant lines. Significant differences in seed protein content were found between parents and their hybrids. It was established that the inheritance of seed protein content in the fi generation included both additive and non-additive gene action, with a preponderance of additive gene action.

The mutant lines, used in the experiment, possess an excess of dominant genes over recessive. The best general combiner among mutant lines was line 310/8.

PHOSPHORYLATION OF STEROID RECEPTORS

Abstract

Radojčić M. (1990): Phosphorylation of steroid receptor. - Genetika. Vol. 22, No. 3, 221-235.

Polypeptide modifications play an important role in determining the spectrum of Particular protein characteristics, frequently generating or modifying their biological activity. Especially interesting is so called transient, dynamic or reversible phosphorylation of proteins, capable of turning "on" and "off" the specific biological activity of a particular protein.

Reversible phosphorylation of proteins seems to be the major tool by which various physiological functions (e.g.: membrane permeability, transport processes, activation of protein synthesis, signal transduction throughout the cell, etc.) are accomplished at all cellular levels. Protein phosphorylation is also involved in the regulation of gene transcription.

Steroid receptors (SRs) are a superfamily of inducible trans-criplional factors that regulate initiation of transcription of steroid regulated gene networks. The members of the SR superfamily share a common structure-function relationship. They are composed of three structural domains comprising several SR functional activities such as: ligand binding, steroid signal transduction (mediated by 90 kDA heat shock protein), nuclear transfer, specific ONA sequence recognition and binding, selfdimerization and transcription activation. Several classes of SR are phosphorylated in vivo in a number of tissues. Multiple phosphorylation sites are detected and mapped to particular SR regions. Functional analysis shows that reversible phosphorylation of SRs may be the mean by which cells regulate ligand binding activity of SRs, partitioning of SRs between cytoplasmic and nuclear compartment and specific gene transactivation.
