Abstract

Marinković D. (1985): Contribution to the evolutionary theory of ageing. V. Age-affected changes in the viability genetic loads of second and third chromosomal homozygotes of Drosophila melanogaster. - Genetika, Vol. 17, No. 1-11

Using a modified technique for isolation of specific chromosomes from wild, carrying such identical 2nd and/or 3rd in a heterozygous state, balanced by corresponding laboratory markers (+^II + +^III/CyUbx). By intercrossing these individuals, progenies were obtained when these parents were relatively young, as well as when they were very old. Among the progenies of young parents, the relative viabilities of homozygotes for the determined 2nd, 3rd, or both wild chromosomes, were characteristic for each fo the specific chromosomes, being within the expected value of cca 33% ("normals"), or below it ("subvitals", "semilethals"), or above it ("supervitals"). However, when the progenies of aged parents were analysed, the relative viabilities of homozygous carriers of chromosomes the studied were significantly changed. To be expressed in a homozygous state, such ageaffected changes must have been similar at identical chromosomes of the agend +/M parents, which suggests that they are a part of an/ontogenetical program during the process of ageing of an individual. The amount of these genetic loads produced at the 2nd or 3rd chromosomes turns out to be approximately the same, suggesting that such changes are characteristic for all parts of the genome of the D. melanogaster flies studied. According to the data obtained, a model of genetic control of ageing is supported, based on the assumption that prevalently recessive micromutations could occur in an onto-genetically programmed manner in each individual chromosome, pro-j- ducing corresponding changes in relevant macromolecula processes.

Abstract

Shivkumar Padmini, Sihgh H. G. and Chauhan Y. S. (1985): Inter-relationship between quality characters in cottonseed. - Genetika, Vol. 17, No. 1, 17-22,

A Study on the inter-relationship between oil, protein, ash, ascorbic acid, gossypol and phosphorus contents in cottonseed of 10 parents, 45 F₁s and 45 F₂s is reported. Protein and free gossypol were found to be negatively correlated at genotypic level. No correlation was found between oil and protein contents. A significant positive correlation was found between protein and phosphorus, oil and ascorbic acid, ash and phosphorus contents respectively in the fi generation at genotypic level. In F₂, significant positive correlation at phenotypic level was observed between protein and ash, ash and gossypol and ash and phosphorus. Significant negative correlation at genotypic level was observed between protein and ascorbic acid, gossypol and ascorbic acid and between phosphorus and gossypol contents.

The mutagenicity induced by a commercial mixture of insecticides (Thimet/Phorate + Lindane) was examined. The mixture Thimet/Phorate + Lindane is designated as "Phoral G". Induction of dominant lethal mutations, chromosomal translocations, reproductive ability in F₁ and F₂ generations and teratological changes in Fj and p2 • generations in male mice (101 X C3H) after a single oral intubation of "Phoral G" was investigated. The data obtained show that ,,Phoral ' G" did not induce dominant lethal mutations and chromosomal^!translocations. Data from the fertility study in P and F₁ generationshowed that "Phoral G" did not induce any effect on fertility. No teratological changes were found in the F₁ and F₂ generations.

The aim of the investigation was to examine whether the insecticide Galition Plus (a mixture of two commercial products - Fenit-rotion + Lindane) induces dominant lethality of offspring or chromosome translocations in directly treated male mice. The experiments were performed on C3H X 101 mice and included analysis of cells treated both at premeiotic and postmeiotic stages of spematogenesis. The results showed that Galition Plus affects neither frequency of dominant lethal mutations nor translocation induction in the cells of treated animals. Also, there were no effects on fertility or terato-logical alterations followed in two successive generations of offspring.

Abstract

Chaudhary S. K. and Anand I. J. (195): Heterosis for seed yield traits in sunflower (Helianthus annus L.). - Genetika, Vol. 17, No. 1, 35-42

Estimates of heterosis were computed in the cytoplasmic hybrids of sunflower involving 16 fertile inbreds and a common cytoplasmic male sterile line for seven characters namely, days to flowering, number of leaves, plant height, "head diameter, seed yield, 1000-seed weight and per cent oil content. Striking estimates of heterosis in the desirable direction were observed for seed yield (71.4%), per cent oil content (43.2%) and 1000-seed weight (40.0%), with estimates for other characters ranged as high as -23.8% for days to flowering, -22.5% for plant height and 19.5% for number of leaves. None of the cross exhibited desired heterotic effects of all characters, however, in one, desired effects were obesrved for four characters. The best cross exhibiting marked heterosis for seed yield was the one, which involved the inbred that possessed genes for pollen fertility restoration.

In these experiments we have examined the cytogenetical characteristics of the black currant (Ribes nigrum), including chromosome conjugation, the tetrad phase, pollen shape and pollen germination of two cultivars of silvergiter's variety, in order to demonstrate some important resemblances or dissimilarities between them. The results showed dissimilarities between the cultivars in degree of anomaly and pollen germination, in meiosis.

GENETIC ANALYSIS OF COMPONENTS OF PLANT HEIGHT IN BREAD WHEAT

Abstract

Singhal N. C., Singh M. P. and Mehra R. B. (1985): Genetic analysis of components of plant height in bread wheat. - Genetika, Vol. 17, No. 1, 53-63.

A diallel cross involving seven varieties of spring wheat having distinct height gradations, was made excluding the reciprocal crosses. The ANOVA for combining ability revealed that both g.c.a. and s.c.a. mean squares were significant for plant height and its components. However, predominantly additive genetic control for plant height and its associated components, was observed except for ear length. The relative rankings of parents on the basis of per se measurement was closely associated with general combining ability effects for all the traits except for number of internodes per tiller. The g.c.a. effect appeared to be more stable than the s.c.a. effects over the environments. Plant height was influenced by its components, except by ear lenght and number of internodes per tiller. However, this relationship did not appear to be associated with the pleiotropic affects. The reduction in number of internodes was not considered a major factor for ultimate expression of plant height. In semidwarf varieties of wheat, the peduncle seemed to contribute, maximally towards plant height expression. The present results do suggest that there is not much scope to develop a genotype with plant height reduced to the range of 50-55 cms, and simultaneously to have a long peduncle as found in tall varieties. However, the cross HD1917 x Mex. C.B.I 16 was found to be promising to obtain a combination of dwarf plant height and relatively long ear.

The introduction of high quality foreign cultivars of apple in different regions of Yugoslavia did not always ensure a suitable assortment of this fruit for the determined areas. Thus, it was felt necessary to create new apple cultivars of high and very high quality which with manifest greater possibilities of adaptation to the ecological conditions of the Polimlje area in Montenegro. In order to achieve the above objective we crossed and investigated hybrids from the following two combinations Jonathan x Lodi and Lodi x Jonathan.

GENETIC VARIATION AND POPULATION DIFFERENTIATION IN PLANTS

Abstract

Tucić Branka (1985): Genetic variation and population differentiation in plants. - Genetika, Vol. 17, No. 1, 83-90.

A survey of the literature on plant allozyme revealed that the majority of plant species maintain a substantial amount of genetic variability within and among their populations. The level and the distribution of genetic variation determined in plants are greatly influenced by their life history variables (generation time, mating system, population size, stage of succession, pollen and seed distribution mechanisms, etc.) and by their adaptation to a coarsegrained environment. It is generally accepted that the microevolutionary factor most responsible for genetic structure of plant populations is natural selection. Thus, the two end points of selection operation at intra-specific level in plants are the high level of genetic variability maintained within their populations and the remarkable population differentiation over the habitat they occupy.
