Abstract
Tucić, B., S. Vujčić and A. Tarasjev (1990): Potential genetic variation in a population of Picea omorika PANC. - Genetika, Vol. 22, No. 2, 73-82.
The level of the potential genetic variation was determined in a population of Picea omorika using different conspecific densities as alternative environments. The quantitative genetic parameters of heritability, heritability of plasticity and genetic and phenotypic correlations within and across densities were estimated for three seedling characters: root, hypocolyl and epicotyl length. The significant genotype- environment interaction for all three characters as well as the high magnitude of heritability estimates for the characters and their plasticity indicate that they could respond to natural selection. The matrix of genetic correlations of characters was unstable across densities suggesting a need for estimating these parameters in a number of different environments if we which to obtain a more accurate prediction about the evolutionary potential of the population to undergo genetic changes under natural selection.

GENETIC STUDIES IN RELATION TO THE IMPROVEMENT OF OIL CONTENT AND SEED YIELD IN SAFFLOWER (Carthamus tinctorius L.)

Abstract
Gupta R.K. and S.P. Singh (1990): Genetic studies in relation to the improvement of oil content and seed yield in safflower (Carthamus tinctorius L.) - Genetika, Vol. 22, No. 1, 83-90.
The variability, herilability and correlation coefficient of oil content, seed yield and its comjionents were determined among 45 F1 hybrids and F2 families, separately. Heritability was high for all the characters in both the generations. The direct selection gain was high in F2 for number of primary branches/plant (43.76%), number of capitula/plant (36.71%) and 100 seed weight (25.79%). High heritability coupled with high genetic advance was observed for number of primary branches/plant, seed yield, oil content, number of capitula/plant and 100 seed weight in both F1 and F2 generations. Seed yield was positively associated with number of primary branches/plant, number of capilula/plant, plant height and 100 seed weight. Among component traits number of primary branches, number of capitula/plant and days to flowering were positively correlated with each other in F1 and F2. Oil content was negatively associated with seed yield and 100 seed weight but positively correlated with maturity traits. To keep the balance of the growth period, the genotypes with medium plant height and maturity coupled with optimum number of primary branches/plant and number of capitula/plant should be taken as criteria of selection for increased seed yield and oil content.

This study was undertaken to determine genetic and phenotypic correlation coefficients among several agronomic characters in flue-cured tobacco varieties, awl to analyse their interrelationships through path coefficient analysis. A secondary objective was to determine broad-sence heritability for various agronomic traits as criteria for selection of yield.

Chosen sublines of the Kg. 56 cultivar were examined with main goals of detecting polymorphism within it and of identifying superior genotypes for some traits. Some morphological, physiological and technological traits were investigated, as well as resistance to disease (in general, traits with high heritability) using standard methods. Polymorphism of sublines was detected within the Kg. 56 cultivar and confirmed on a biochemical basis, by polyacrylamioe eel electrophoresis of grain endosperm gliadins. Using the acid PAGE- method 4 different genotypes were identified in relation to gliadin composition, and on the basis of the remaining analyses 11 sublines were identified.

Abstract
Terzić, R. (1990): Population genetics of the main ABO and Rh system blood groups in the population of Bosanska Krajina. - Genetika, Vol. 22, No. 2, 117-124.
We have investigated the frequency of alielogenes in all 24 Bosanska Krajina communes (analysed sample includes 42905 voluntary blood donors: Banja Luka region 32867; Bihać region 10038). Gene frequencies and their adaptation to the appropriate theoretical sum (- 1000) have been determined by standard procedures and the evaluation of within- group and between- group variations of the observed parameters has been done by analysis of the standardized Wahlund variance of recessive allelogenes.

The relative importance directional (DA) and fluctuating (FA) asymmetry to character variation was examined in a laboratory population of the heari weevil (Acanthoscelides obtectus). DA in females was less than 1% of the mean length of each for the four bilateral characters. FA was calculated as error variance from two-way ANOVA. The average contribution of FA to the total phenotypic variance was about 20%. The average narrow sense heritability of DA was about 6%.

Analysis of the genetic structuring of complex populations of Triturus cristatus showed that populations from Yugoslavia differ in genetic variability level from those inhabiting regions of Central Europe. The high level of genetic fragmentation between populations was estimated by hierarchical F-statistics parameter values and in supported by estimates of gene flow level using different approaches. The empirical curve constructed for average number of migrants per generation showed the greatest similarity to the theoretical one for an island model of population structure. The pattern of the empirical curve suggests that some investigated populations were from a secondary contact zone.

Coronary artery disease (CAD) is the leading cause of morbidity and mortality in most industrialized countries. Disorders of the lipid transport system resulting from complex interactions among nutritional, environmental and genetic factors, play a very important role in the development of the disease. It has been proposed that high levels of LDL particles, which cause cholesterol deposition in the arterial wall, and/or low levels of HDL particles, which promote cholesterol efflux this site, have been associated with increased risk of CAD. Recently, interest has been focused on apolipporotein Al and apo B, the major protein components of HDL ana LDL. There is a need to examine, at the DNA level, the genetic variation that is involved in determining the serum levels of these apolipoproteins. DAN probes for these genes have also been identified and we can attempt to detect and define this genetic variation by using restriction fragment length polymorphism (RFLP). This provides important new information about the molecular biology of each locus and about mutants that may predispose to vascular disease. There are three different ways to approach this which are discussed in turn: family studies, studies in group of patients and studies within the normal population.
