Abstract
Djordjević, B. (1981): Radiation lethality in synchronous Hela cells containing 5-bromodeoxy-uridine. - Genetika, Vol. 13, No. 1, 1-12.
Cultures of HeLa cells with DNA altered by partial incorporation of 5-bromodeoxyuridine (BUdR), are not only more sensitive to ionizing radiation than normal cells, but have an altered response to radiation during the division cycle. Namely, the typical sinusoidal age-response seen in irradiated HeLa cells is almost flattened in cells containing BUdR. Such a reduction in fluctuation of radiosensitivity in the latter cells is interpreted by a deleterious effect of the altered DNA on the replicative apparatus of the cell, at the time when normal cells become radioresistant. Disturbances in the replicative apparatus may be also responsible for the increased lethality when BUdR is incorporated after irradiation. In these cases one apparently deals with the potentiation of radiation damage, and not with a reduction of the innate ability to repair radiation damage.

Abstract
Kaul, M.L.H. and Garg, R. (1981): Radiation-genetic studies in garden pea. X. Performance, interrelationships and genetic parameters of high protein pea lines. - Genetika, Vol. 13, No. 1, 13-25.
High intra- and inter-phenotypic and - genotypic variations were found in the metric traits of 16 high protein pea lines developed through mutation breeding. Maximum variability existed in total grain yield and seed number per genotype. Since selection intensity throughout the breeding experiments was directed towards higher seed protein content, its range of variability was the lowest.
Breeding value of the trait seed number per plant is high since it exhibits a high genetic coefficient of variation, heritability and expected genetic advance, and is strongly positively correlated with grain yield. Coefficient of correlation values (bivariate, partial and multiple) and regression equations indicate a strong dependence of grain yield upon the trait seed number per plant whose breeding value is enhanced still more.
Coefficient of multiple determination reveals that 65-67% of the variance in grain yield is accounted for by its association with seed and pod number per plant, the remaining being due to the action and interaction of other variables including the environment.
Since sufficient genotypic variability exists in the trait seed number per plant, it is possible to bring about an improvement in the through recurrent selection without influencing seriously the other metric traits of these high protein pea genotypes.

A new case hi which a 15/15 translocation is accompanied by mental retardation and some sings of physical abnormalities, is reported. A review of the literature indicates that such a translocation has been described earlier, twice in normal women and four times in, cases of Prader-Willi syndrome.

Abstract
Malek, M.A. and Borojevifi, S. (1981): Genetic analysis of yield components in wheat. - Genetika, Vol. 13, No. 1, 33-39.
Diallel analysis involving six wheat varieties was evaluated for three important components of yield, namely, number of spikelets per spike, number of kernels per spike and 1000-kernel weight.
The components of genetic variation and graphical analysis of the variance-covariance regression indicated additive effects for all the three yield components with partial dominance for the number of spikelets and kernels per spike and overdominance for 1000-kernel weight.
The Yugoslav parent Sava had favourable alleles for the number for spikelets and kernels per spike, the Mexican parent Siete Cerros had favourable alleles for the number of kernels per spike while the Russian parent Bezostaya-1 had the same for the number of spikelets per spike and 1000-kernel weight.

Grain yield per plant and per plot were assessed in half-sib family groups produced in an experimental composite of mize according to the Design I mating system of Comstock and Robinson {1948, 1952) and tested at two locations. Additive genetic variance was the major component as revealed in combined location analysis and also at one location. Additive genetic variance was more stable over the locations. The predicted genetic gain from full-sib family selection was three times more than that from mass selection.

NUMBER OF PRIMARY ROOTLETS IN WHEAT, A POTENTIALLY USEFUL TRAIT FOR BREEDING IMPROVEMENT

Abstract
Tomasović, S. (1981): Number of primary rootlets in wheat, a potentially useful trait for breeding improvement. - Genetika, Vol. 13, No. 1, 49-57.
A study was made of the number of primary rootlets of 40 genotypes of winter wheat Triticum aestivum ssp. vulgare. The investigations were carried out under laboratory conditions, at room temperature and humidity, in 2 trails during two years (1973 and 1974). The data obtained were processed according to the block method of analysis of variance. In addition to the common vulgare genotypes, the analysis also included branched and four—rowed lines, as well as lines derived from the cross branched x vulgare. It was established that the branched gene complex caused the development of a larger number of primary rootlets than the common vulgare genotypes. A comparison was made of the studied genotypes and great variation was recorded in the character ,,number of primary rootlets". The number of primary rootlets is a very important quantitative character which can be used in breeding to discard superfluous genotypes. Thus, it speeds up the wheat breeding process.

Abstract
Penčić, V., Hooker, A.L. and Lević, J. (1980): Reaction of American maize germ plasm and gene stocks to leaf disease pathogens in Yugoslavia. - Genetika, Vol. 13, No. 1, 59-68.
Stability in the resistance of the maize plant very often depends on the pathogen and ecologic conditions of the region where it spreads. Therefore, the reaction of different maize genotypes from the U.S.A. (Illinois) with incorporated genes for resistance to some leaf diseases was investigated at the Maize Research Institute, Zemun Polje, Beograd-Zemun, Yugoslavia (Puccinia surghi, Helminthosporium turcicum, Helminthosporium carbonum, Kabatiella zeae).
In this paper particular stress is given to the investigation of maize resistance to Helminthosporium turcicum which is one of the economically most significant pathogens of maize leaf diseases. In 1979 the following materials were tested: (a) breeding material with gene sources of resistance to: H. turcicum (Ht, Ht2, Ht3 and HtN) and Puccinia sorghi (Rp); (b) inbred lines and hybrids to: Helminthosporium turcicum, Helminthosporium carbonum and Kabatiella zeae, (c) composites were also tested in 1978 and 1979 to Helminthosporium turcicum.
The reaction of all investigated materials was tested in conditions of artifical inoculation with H. turcicum, Kabatiella zeae and H. carbonum. The reting of resistance to Puccinia sorghi was made in conditions of natural infection.
Prior to tasseling, determinations were made of type of spots as one of the most important indicators of the incorporated gene for resistance to H. turcicum. In addition, once a week after silking, for each individual disease determinations were made of t...e percent of green leaf area in both inbreds and hybrids, i.e. the active part of the plant leaf affecting the yield, (PGI). This is one of the more important indicators for determining the resistance of maize breeding material to individual diseases in relation to determining the index of disease.
The results of our investigation show that sources and genes for leaf disease resistance selected in Illinois also function in Yugoslavia and can be expected to function elsewhere in Europe.

Abstract
Mrčalica, E. (1981): Efect of selection of parent pairs on the secondary sex ratio of the fruit fly (Drosophila melanogaster). - Genetika, Vol. 13, No. 1, 77-94.
The observed variability in sex ratio has served as a basis for selection directed towards decrease and increase of masculinity. The selection has lasted for 40 generations.
This experiment, performed on the fruit fly Drosophila malanogaster, has provided data for biometric and genetic analysis of the observed feature.
The point of selection reached is 39.45± 1.06% males in the line directed towards a decrease of masculinity and 51.22 ± 1.23% in the line directed towards an increase of masculinity, which represents considerable deviation from the control line with 46.34 ± 0.01% of males.

The genetic heterogeneity of 13 local human populations in Bosnia and Herzegovina (Yugoslavia) has been studied with regard to five phenotypic systems of qualitative variation (ABO blood groups, ABH antigens secretion, PTC tasting, red and green colour vision). The study was carried out by analysing: (1) the variation range and (2) standardized Wahlund's variance of gene frequencies, and (3) the "kinship coefficient" (observing all the phenotypic systems).
