Abstract

Vasilj, Đ. and Milas, S. (1981): Analysis of genotype x environment interaction for estimation of the stability of some quantitative characters. - Genetika, Vol. 13, No. 2, 105-114.

This study was conducted to determine how the yield stability of some released maize hybrids and wheat varieties differed when they were grown in a number of environments.

Analyses were based on data from experiments conducted on six (for maize) or five (for wheat) locations over a three year period. Six single cross hybrids (FAO group 400) and two standards for maize, as well as four new varieties of wheat and their four standards were included in this study.

Stability is described by the following parameters: mean yield (y), regression of mean yield on an environmental index (b) and the estimation of the remaining interaction component of variance in genotype x environment interaction, due to the contribution of each genotype (S²_GxL).

Abstract

Javornik, B., Eggum, B.O. and Kreft, I. (1981): Studies on protein fractions and protein quality of buckwheat. - Genetika, Vol. 13, No. 2, 115-121.

The proteins of Siva dolenjska buckwheat were separated into protein fractions comprising 18.2% albumins, 43.3% globulins, 0.8% prolamins, 22.7% glutelins and 15.0% of inextractable nitrogen compounds. The low prolamin content corresponds to the favourable ami-no acid composition of buckwheat in comparison with other cereal proteins. The chemical composition and protein quality of Siva dolenjska groats and tartary buckwheat were studied and compared with whole seeds of Siva dolenjska buckwheat. Assessment of the protein quality of Siva dolenjska groats and tartary buckwheat was based on the amino acid composition and N-balance experiments with rats. The protein quality of groats was very high, with a biological value above 90% which is the same as that for whole seeds. The true protein digestibility of groats was about 10% higher than for whole seeds which is probably due to a much lower content of crude fibre and tannin in groats. The biological value of tartary buckwheat was above 80%, which however is much lower than for common buckwheat. This might be explained by a lower availability of the limiting amino acid. True protein digestibility of tartary buckwheat and common buckwheat was below 80% due to the high content of tannin and crude fibre.

Abstract

Rawhat, D.S. and Anand, I.J. (1981): Analysis of genetic divergence in brown mustard. - Genetika, Vol. 13, No. 2, 123-128.

A study of genetic divergence using Mahalanobis D² statistic was conducted on 27 strains of Indian brown mustard (Brassica juncea (L) Czern and Coss) for seven characters related to yield and fitness. Considerable variability was observed among strains for all characters. The various strains were grouped in seven clusters on three diverse lines. Parallel variation was observed between clusters III, IV and VII on one line, and I, II and V on the other, with cluster VI diverging from the rest. The geographical diversity of strains was found not to be related with the genetic diversity. The characters that contributed maximally to divergence were days to flowering, plant height and 1000-seed weight in that order. Based on inter-cluster diversity, selection of genetically diverse strains to be used effectively in a breeding program for generating superior recombinants is suggested.

Line x tester analysis of combining ability in rice was conducted with the aim of obtaining information on the genetic architecture of the population and also to isolate the best parent for hybridization. Parent vs F₁s showed significant differences for all the characters except days to flower andd flag leaf length indicating a substantial amount of heterosis for these traits. Parents Bala, Cauvery, Krishna, FH109 and Sona were good combiners and IR24 x N22, Cauvery x T3, Bala x T3 adn Pusa 2-21 x N22 were promising hybrids. Per se performance of the parents was losely associated with general combining ability effects.

The variation in the duration of preimaginal development and imaginal lifespan within and between different natural populations of Drosophila melanogaster has been studied. Our data suggest a negative relationship between duration of preimaginal development and longevity of D. melanogaster individuals. Differences in recombination frequency and adult lifespan between populations show that populations whose individuals have an exceptionally long adult life, have a relatively higher recombination frequency. The obtained results are discussed in the ligth of the significance of gene recombinations and repair mechanisms in modulating species-specific longevities.

BREEDING OF WHEAT FOR RESISTANCE TO FUSARIUM DISEASES, ESPECIALLY TO FUSARIUM GRAMINEARUM AND CREATING A MODEL FOR INHERITANCE OF RESISTANCE IN NEW WHEAT CULTIVARS

Abstract

Tomasović, S. (1981): Breeding of wheat for resistance to Fusarium diseases, especially to Fusarium graminearum and creating a model for inheritance of resistance in new wheat cultivars. -Genetika, Vol. 13, No. 2, 177-187.

The Fusarium disease was discovered in 1884 by Smith, who called it "wheat scab". The disease was widespread in Europe, Australia, Canada, and North America, but it is most destructive in the U.S. Corn Belt where it ranks as one of the most destructive diseases of wheat and corn. In North America scab disease has been reported in all U.S. wheat growing regions east of the Rocky Mountains as well as in Utah and Oregon.

Fusarium disease usually occurs as a head blight in the temperature, humid, and semi-humid zones of the world. Seedling blight and root rot phases of it exist in dry areas. It attracted little attention until 1915, when it became sufficiently prevalent, especially on Marquis wheat, to cause yield losses.

The principal pathogens that cause wheat scab are Gibberalla saubinetii (Mont.) Sacc. Fusarium graminearum Schwabe (Gibberella zeae). Gibberella zeae the perfect stage of Fusarium graminearum, causal fungus, is the most important soil-borne pathogen that attacks wheat plants over the whole world, but especially in environments that favour its development.
