Lazić-Jančić, V., V. Hadži-Tašković Šukalović, M. Vuletić, M. Denić and S. Neyra (1991): Genetic variability of aluminium stress tolerance in maize. - Genetika, Vol. 23, No. 1, 1-14.
Sixty-two inbred lines were initially tested for aluminium tolerance on the basis of root and shoot sensitivity to the stress. Typically roots were more affected than shoots. The root system lacked fine branching and was reduced in size. All genotypes screened showed at least a 30% reduction of root length and 56 out of 62 a reduction of more than 60%. By combining two parameters (relative root and shoot length) only 5 genotypes out of 62 might be considered tolerant to high Al. Differences in root and shoot dry matter yield did not help to distinguish maize genotypes for Al tolerance in 12-day old plants.
The higher Al treatment resulted in substantial accumulation of this element in the roots, 10-16 times higher than in the shoots (varying with genotype). The Al stress also resulted in a significant reduction of Ca and Mg in both roots and shoots. However, phosphorus uptake or accumulation was less affected.
Tolerant plants were more resistant to Al and maintained near normal growth at the same concentration of Al compared to sensitive plants.

Abstract
Halda L., F. Stumpf, E. Brandmuller and W. Klingmfiller (1991): Nitrogenase activity of Enterobacter strains at various temperatures. - Genetika, Vol. 23, No. 1, 15-24
Nitrogenase activity (conversion of acetylene into ethylene) of representative nitrogen fixing Enterobacter species associated with wheat and maize rhizosphere showed optimal nitrogen fixation (using the acetylene reduction test) between 22°C-26°C in experimental conditions when aspertate was not supplemented. The same range for optimal nitrogen fixation was obtained in the case of Escherichia coli HB 101 strain which contains the nif region of Enterobacter agglomerans. Thus, the constructed strain with nif genes followed the behaviour of the wild type strain. The highest rate of increase for all tested strains was at 26°C. Nitrogen fixation at temperatures lower than 16°C and higher than 34° showed an almost negligible increase of nitrogenase activity. The investigation of the effect of temperature on the level of gene regulation of nitrogen fixation by nif A gene showed that the nitrogen fixation in Enterobacter species is relatively termostable.

Abstract
Laća Ž., S. Morić-Petrović and O. Ristić-Marinković (1991): The rare, heritable, fragile sites in human karyotype and chromosomal aberrations. - Genetika, Vol. 23, No. 1, 25-31.
The rare, heritable, fragile sites on human chromosomes have been defined and classified according to their expression under different conditions of tissue culture. At present the precise mechanism of fragile site formation is unknown as well as the relationship with chromosomal aberrations, predisposition for the development of malignant diseases etc. The function and identity of genes located at the fragile sites remains an enigma. In spite of the many unresolved issues, we should be aware of the research in this area because of its importance in the first place, in prevention of diseases.

ECO LOGICAL VARIABILITY OF INDICATORS OF SEED QUALITY IN WHEAT

Abstract
Rajnpreht, J. and I. Mihaljev (1991): Ecological variability of indicators of seed quality in wheat. - Genetika, Vol. 23, No. 1, 45-62.
Seed quality is a complex property affected by genetic inheritance and, to a high degree, by factors of the environment - different localities and years. In four wheat varieties, the effect of some environmental factors on formation of particular components of seed quality was studied on fourteen localities, in the course of two years. Highly significant differences between varieties were found concerning size, 1000 seed weight and other properties as well as between localities and years and their interactions. Considering all localities and both years, the variety NS rane 2 provided the highest quality seed.
The interaction variety/environment of the most significant quantitative properties enables the choice of varieties of desirable adaptability which are stable in different agroecological conditions.

Abstract
Mihailović, V., and M. Kraljević-Balalić (1991): Inheritance of stem height in spring forage pea. - Genetika, Vol. 23, No. 1, 81-87.
Stem height is an important trait in forage pea whose expression is governed by several genes. Since forage peas and peas for grain must differ in stem structure, it is understandable why their breeding programs differ. The study discussed in this paper included diallel crossings, without reciprocals, of four diverse forage pea varieties which were analyzed for mode of inheritance, gene effect, heritability and combining ability in the F1 and the F2 generation for stem height. Heterosis and dominance were observed for the inheritance of stem height in the F1 generation, intermediacy and partial dominance of the taller parent in the F2 generation. Additive genes were found to be more important for the inheritance of stem height than non-additive ones.
