Brkić N., Ž. Gajić, and M. Pušić (2001): The genetic and phenotypic variability and relationship of some growth and slaughter characteristics of the performance tested gilts. – Genetika, Vol. 33, No. 1-2, 1-do.
Evaluation of the breeding values as a result of performance tested gilts was carried out at the farms "Vizelj" and "Ratari" and at the both farms the tested gilts achieved the body weight of 103.81 kg at the average daily growth rate of 0.491 kg within the period of 209.25 days. At the end of the test live animals were measured by ultrasound machine (PIGLOG 105) and it was found that the average backfat thickness was BT1 20.09 mm, BT2 15.25 mm and BTA 17.67 mm, the average muscle depth was MLD 45.25 mm and the average lean meat content was 52.92%. The gilts F1 generation Svedish Landrace x Large White (SLxLW) achieved better results concerning growth rate and lean meat content indications in comparison with the gilts purebreed Svedish Landrace (SL), while statistically significant differences were found out by the t-test (P<0.01) between the breeds all tested characteristics except for the backfat thickness BT1 and muscle depth (MLD), where the results were statistically nonsignificant (P>0.05). High heritability is noticed with the characteristic indicating backfat BT1, BT2 and BTA as well as the lean meat content (h2 0.561 to 0.776), while the depth of MLD shows low heritability (h2 0.077) and the daily growth rate shows medium heritability (h2 0.254). The established genetic correlations between the backfat thicknesses are complete (rg 0.972 up to 0.993) as well as between the backfat thickness and the lean meat content where the correlations are negative and complete (rg -0.988 up to -0.999), while between backfat thickness and MLD are low and negative (rg -0.192 up to -0.299).
Key words: gilts, performance test, lean meat content, growth rate, heritability, genetic correlations

Abstract

Douglas fir (Pseudotsuga menziesii /Mirb./ Franco) is the most important introduced conifer species in Europe. Adaptation of introduced species can be assessed by provenance tests. In this aim the provenance test was established in East Serbia et the site Tanda of 29 different Douglas fir provenances, originated from Oregon to Washington. This paper deals with the dependece, of the provenance latitude, longitude and altitude on the hight increment of tests trees grown on allohtoneus sites. The results show that latitude has a low effect on hight increment of plants of different provenances, and that the effects of longitude and altitude are very important. Significant differences were observed between the provenances in the same site conditions, so it is supposed that the differences are caused, primarily by gene pools of provenances, and their geographic characteristics. Staistical analyses prove the highly significant differences of the provenaces, which impose high attention in the choice of adequate ones.
Key words: Douglas fir, provenances, height increment, geographic characteristics

Abstract
Dražić S. and S. Prodanović (2001): Phenotypic divergence of burley tobacco varieties. – Genetika, Vol. 33, No. 1-2, 19-do.
Seven traits (duration of growing season, height, leaf number, length and width of mid plant leaf and yield) in 20 burley tobacco varieties were observed. Significant differences of their values, i.e. great variability of traits among observed genotypes were determined. The degree of their divergence was esteemed by hierarchical cluster analysis. One of two produced dendrograms was based on varietal divergence by more important traits of development and morphology, i.e. yield components, while the second dendrogram was also based on this complex. Three (I-1, II-1, III-1), i.e. two clusters (I-2, II-2), are observable on the first, i.e. the second dendrogram, respectively. Genotypes of similar productivity were found within each cluster, indicating that selected yield components were the basis for breeding of barely tobacco for yield. When planning hybridisation, parents should be selected from different clusters or subclusters in order to recombine genotypes as divergent as possible over their quantitative properties.
Key words: burley tobacco, divergence, germplasm, yield, yield components

We investigated the association between insertion/deletion (I/D) polymorphism at angiotensin-converting enzyme (ACE) locus and high blood pressure in a case-control study performed on population of Caucasians (175 females and 210 males). Case subjects were those with untreated borderline hypertension. Significant and moderate, male gender-specific, independent association between DD genotype and high blood pressure was found. Adjusted odds ratio (OR) is 2.0 (95%CI, 1.1 to 3.9; P=0.03) in the whole group and 2.5 (95%CI, 1.2 to 5.1; P=0.01) in the group truncated on the basis of age (≤50 years). Our findings support the hypothesis that ACE is a gender-specific candidate gene for hypertension.

Abstract
Bhargava S.K., S.T. Christiana, and T.M. Veeraiah (2001): Genotype-environment interaction for silk yield contributing characters in silkworm, Bombyx mori L.. – Genetika, Vol. 33, No. 1, 39-52.
42 strains of silkworm (Bombyx mori) of different geographical origin were evaluated for stability performance. Data of three seasons (autumn, spring and summer) was analysed statistically by using regression method, for silk yield contributing characters namely pupation rate, cocoon weight, shell weight, shell ratio and filament length. The results indicated the significance of genotypes/strains, environment and genotype x environmental interaction for all the five characters. Environmental index revealed that autumn (September-October) is the most favourable season for exploiting all the five characters. Considering the stability parameters, the most stable strains for different characters are as follows, NJ1 (cocoon weight, shell weight, shell ratio and filament length) CJ3P and SSOP (pupation rate, shell ratio and filament length), Dong 306, NB1 and SPC1 (pupation rate and filament length), strain 247 and J1M (pupation rate and shell ratio). The strains selected will be used in developing new breeds and lines.
Key words: genotype environment interactions - stability - regression co-effcients
