Nikolić Vladislava, Milošević-Jovčić Nadežda, Mijatović Njegoslava and Šušaković Nadezda (1987): Frequency of Gm factors of immunoglobulin G among several populations in Serbia. - Genetika, Vol. 19, No. 3, 183-197.

The distribution of Gm factors 1,2,3,5 and 11, the incidence of appearance of Gm phenogroups as well as the homo - and heterozygosity for the two major of them was studied among inhabitants of four towns in Serbia. It was shown that the incidence of Gm factor appearance differed among the investigated groups. The greatest differences were demonstrated for Gm 1 and Gm 2 frequency. This fact significantly influenced the incidence of Gm phenogroups, increasing Gm heterozygosity among some populations. Migration as well as intergroup union of immigrants in some areas was stressed as a possible reason for the uncommon distribution of Gm factors.

Abstract

Ahmad Z., Singh Y.P., Singh K.N. and Srivastava V.K. (1987): Heterosis for yield components and quality traits in spring wheat. - Genetika, Vol. 19, No. 3, 199-204.

In 28 F₁s involving 8 diverse genotypes of spring wheat, heterotic effects over the better parent were analysed for grain yield, its components and some quality attributes. Highest mean heterosis was obtained for phenol colour reaction (21.23%) followed by grain yield (20.46%), biological yield (16.88%), productive tillers (11.31%), 1000-grain weight (10.80%) and weight of grains per spike (9.68%). Thirteen crosses gave significantly higher yield than their respective better parents. Biological yield and productive tillers made the greatest contribution towards the increase in grain yield. Quality attributes, specially seed hardness, gluten content and phenol reaction moved in a desirable direction in some of the high yielding heterotic hybrids. Generally, negative heterosis was recorded for protein content. The best F₁s involved parents of high x low performance for yield, biological yield, seed hardness and phenol reaction, and low x low for gluten content.

A wide and extensive hybridization programme has been initiated in spring wheat, though the information regarding desirable parental combinations showing high heterotic levels for biological yield, harvest index and important quality attributes is limited. The present study was designed to determine heterosis in yield, its components including biological yield and harvest index, and important quality traits, viz; protein, gluten, phenol colour reaction and seed hardness in spring wheat (Triticum aestivum L.).

BREEDING SYSTEMS IN BUCKWHEAT (FAGOPYRUM SPP.) CULTIVATED IN KASHMIR

Abstract

Thair I. and Farooq S. (1987): Breeding systems in buckwheat (Fagopyrum Spp.) cultivated in Kashmir. - Genetika, Vol. 19, No. 3, 205-208.

A comparative study has been made of the breeding system in the four buckwheats viz. F. esculentum Moench, F. sagittatum Gilib., F. tataricum Gaertn. and F. kashmirianum Munshi. F. esculentum, besides being predominantly heterostylous, shows dimorphism of pollen grains and stigmas compared to the other three species which are predominantly homostylous. The effective pollination in F. esculantum is largely entomophilous in contrast to the other three species. In F. esculentum seed set in open pollinated inflorescences was markedly higher than in bagged inflorescences whereas, no appreciable difference was recorded in the seed set between open pollinated and bagged inflorescences for the other three species. This substantiates the assumption that F. esculentum is essentially self incompatible whereas, the other three species are self compatible.

MODIFIED MASS SELECTION FOR LARGER HEAD SIZE IN A COMPOSITE MIXTURE OF SUNFLOWER

Abstract

Mishra R. and Chaubey C.N. (1987): Modified mass selection for larger head size in a composite mixre of sunflower. - Genetika, Vol. 19, No. 3,209-216.

A composite mixture of thirteen diverse genotypes of Sunflower was subject to two cycles of modified mass selection for larger head size. The efficacy of selection was evaluated by application of the Design-I mating scheme of Com stock and Robinson (1952). Selection for larger head size was found effective in increasing head size significantly by a margin of sixteen per cent as compared to the base population but the seed yield was found to reach a threshold limit after the second cycle of selection and it was, therefore, found to be adversely affected. The present investigation suggested that the development of a population bearing very large heads is not beneficial in terms of obtaining a higher seed yield. The selection for larger heads brought appreciable changes in the associated characters as expected.

There is growing interest among maize breeders in the application of molecular genetics to maize research. As genetic variability is most important in breeding progress, its determination by the use of new technologies based on molecular genetics will be of great benefit. In this report, quantitative polymorphism for repeated DNA sequences (rDNA) was used as a method for detecting genetic variation of maize inbred lines belonging to different FAO maturity groups. The effect of heterosis was also studied using the same molecular probe.

Both quantitative and qualitative differences were obtained between inbred lines and some hybrid combinations.

Živković S., Fišter S. and Vujošević M. (1987): Cytogenetic analysis of fishes from the Perddae (Pisces) family. - Genetika, Vol. 19, No. 3, 227-232.

Karyotypes of several species (Perm fluviatilis, Stizostedion volgensis, Acerina cernua and Acerina schraetser) of insufficiently studied Percidae (Pisces) family were determined. Chromosome numbers of all examined specimens of these species was 2n = 48, with the exception of one perch sample where an aberrant karyotype form was observed (2n = 49). The non-matched metacentric chromosome by all probabilities resulted from the fusion of two telocentric chromosomes.

Abstract

Castro J.A. and Mensua J.L. (1987): Larval competition in tricultwes of Drosophila melanogaster: A geometrical approach to the larval competitive process. - Genetika, Vol. 19, No. 3, 233-250.

Employing three strains of Drosophila melanogaster, a wild strain and two eye colour mutant strains, cardinal and sepia, a geometrical approach to the larval competitive process in tricultures has been developed. For this purpose, seventy different points of genotypic composition were chosen. These points put in a three dimensional diagram with the axes wild, cardinal and sepia make up an equilateral triangle plane (input plane). The input plane might change after the competitive process, this change depending upon the competitive ability of the strains in competition. The different situations which theoretically can occur are discussed. This method can be employed to survival but not to other fitness parameters such as developmental time. To complete the geometrical approach, other statistical methods, like multiple linear regression analyses have been employed. The results indicate a competitive constancy of the strains with respect to viability, while in developmental time, the interactions among larvae result in frequency-dependent behaviour.

Abstract

Šoltes-Rak E. and Rajčan-Šeparović E. (1987): Genetic engineering - gene manipulation in plants. - Genetika, Vol. 19, No. 3, 251-262.

Genetic engineering methods are becoming widely used in plant breeding today. Transfer of genetic information from procariotes and eucariotes to plant systems and between different plant species requires a vector system for integrating genes into the plant genome. The aim of this article is to give a brief review of vector systems in current use for gene manipulation in plants. Furthermore, some practical applications of vector systems in plant improvement are described.
