Abstract
Ristić O., Laća Z. and Morić-Petrović S. (1987): Theoretical discussion of the X/autosomal translocations and a case report 46, X, der(X), t(X; 15)(q13;q24). - Genetika, Vol. 19, No. 1, 1-7.
By cytogenetic analysis the karyotype of a three-year old proband, with abnormalities, was found to be 46, X, der(X), t(X; 15) (q13; q24). RBA technique was applied for detecting late replicating X chromosomes. In all 12 cells analysed the normal X chromosome was late replicating. Because of the presence of multiple abnormalities, it was supposed that a certain number of cells carry an X chromosomes, involved in translocation, as a late replicating one. The existence of a spreading effect of inactivation to the autosomal portion of chromosome 15 was also assumed.
Pointing to similar examples in the literature, the discussion deals with the possibilities and mode of inactivating the X chromosome, the origin of X/A translocations, correlation between phenotype 'and genotype, and the application of biochemical techniques in addition to cytogenetic investigations.

Abstract
Tucić N., Cvetković D., Milanović D. and Lazić M. (1987): Genetic variation in fitness components and recombination rates in Drosophila melanogaster females. - Genetika, Vol. 19, No. 1, 13-25.
This paper concerns the genetic variation and covariation in life history fitness components and recombination rates in Drosophila melanogaster females. Estimates of heritability, although confounded by dominance variance, showed that in natural populations of D melanogaster genetic variation for fitness components and recombination rates exist. The phenotypic correlations among fitness components as well as between recombination rates and fitness were partitioned into genetic and environmental parts by analysing the variation and covariation within and among the progeny of full sibs. The genetic correlation between early fecundity and longevity was negative, indicating antagonistic pleiotropy between these characters. We also found negative genetic correlation between fecundity and recombination rate but positive correlation between longevity and recombination rates. Implications of these findings for the theory of life history evolution and for the evolutionary theories of ageing are discussed.

Rate and duration of grain filling and oil accumulation were measured in nine single cross hybrids of corn (Zea mays L.) which differs! in percent oil in the grain and in agronomic performance. Hybrids B73 x Mol7, B73 x LH38, and B73x H99 had c. 5% oil in the kernel. Hybrids B73 x R806, B73 x 96, and B73 x 137-9c contained 7% oil, and hybrids B73 x 465, B73 x 484, and B73x560 had 9%. The hybrids were grown in 1984 in a randomized complete block design with four replications at Urbana, Illinois, U.S.A. and Zemun Polje, Yugoslavia. Three ears were harvested from each plot 21 days after pollination and at weekly intervals thereafter until 70 days after pollination. Hundred kernel weight and percent oil were determined for each hybrid at each harvest date and location.
Standard" oil' hybrids had a higher grain filling rate than high oil hybrids. The average grain filling period of standard oil hybrids was slightly longer than in high oil hybrids. No hybrid x location interaction for grain filling rate was found.
High oil hybrids had a higher oil accumulation rate and longer oil accumulation period than standard oil hybrids. Hybrid x location interaction was not a significant source of variation in accumulation rate.
Most of the variation in mature kernel weight could be explained by regression models which include grain filling rate, grain filling period, kernel weight 21 days after pollination and percent oil in the grain as independent variables.

Abstract
Ivanović M., Stojnić O. and Greder R.R. (1987): Correlations among grain yields of full-sib, half-sib, and selfed progenies in broad and narrow base populations of maize (Zea mays L.). Genetika, Vol. 19, No. 1, 37-45.
Correlations among grain yields (t/ha at 14% moisture) of selfed (S), half-sib testcross (HS), and full-sib (FS) progenies within the narrow-based (NBPXB73 x Mo17)F2 and broad-based (BBP)ZP Sin S4C0 maize populations were analyzed in two environments in 1986. Mean grain yield was lowest for selfed progenies, intermediate for FS, and highest for HS progenies in both populations. The highest correlation among progeny types was observed between those families created within the population itself (i.e. FS vs. selfed progenies) and was the same regardless of the composition of the population (NBP vs BBP). The low correlations of testcross families (HS) to FS and S progenies, indicate possible masking effects of the elite line tester ZPL 1607/3. Differences between populations for these correlations may be due to dissimilar gene frequencies, sampling differences, linkage effects, and/or differences in the ratio of additive to nonadditive variance between populations. Of the 10 highest-yielding lines for any single progeny type a it minimum of one and a maximum of three families" were also ;» identified by a second method indicating that the genetic effects being selected for by the three methods are quite different. However, two families in BBP and one in NBP were in the top 10 for all progeny types suggesting that lines possessing favourable dominant alleles, lacking deleterious recessives, and containing heterotic components may be identified.
Simultaneous combined selection based on several progeny types should provide lines improved for additive and nonadditive effects.

Abstract
Kralj D. and Haunold A. (1987);, Breeding potential of native hops (Humulus lupulus L) from Yugoslavia. - Genetika, Vol. 19, No. 1, 47-60.
The analysis of sources of variability of certain wild hops and their progeny in Yugoslavia revealed the influence of male and female parents on certain properties. It also allowed an estimate of the general combining ability useful for hop breeding. The native male hop 07P14 had a high genetic potential for breeding European aroma-type hops. The male 20P09 transmitted high yield potential to its progeny while the male 35P01 transmitted above average alpha and beta acids content and a high yield potential.

Abstract
Farooq S. and Tahir I. (1987): Species relationship in buckwheat (Fagopyrum Spp.) through electrophoresis of proteins and enzymes. - Genetika, Vol 19, No. 1, 61-65.
A comparative study has been made of the electrophoretic patterns of proteins and isoenzymes separately in grains and in leaves of four species of Fagopyrum viz. F. esculentum Moench, F. sagittatum Gilib., F. tataricum Gaertn. and F. kashmirianum Munshi. The intrageneric relationship between the four buckwheat species has been determined by comparing the polygraphs of various species separately in grains and in leaves. F. esculentum stands out distinct, whereas F. sagittatum, F. kashmirianum and F. tataricum show a good deal of resemblance in the polygraphs. Among the latter three species, however, F. sagittatum and F. kashmirianum show remarkable resemblance, whereas F. tataricum stands somewhat apart.

Abstract
Saha B.S., Mehta D. K., Pujari M.M., Jain B.P. and Brahmachari V.S. (1987): Genetic variability in fennel (Foeniculum vulgare Mill.) - Genetika, Vol. 19, No, 1, 67-71.
The present investigation was carried out to study the genetic variability in twenty five lines of fennel at Bihar Agricultural College, Sabour, Bhagalpur, Bihar, India. Data were recorded on plant height, plant spread, stem-girth, number of primary and secondary branches per plant, number of umbels per plant, 1000 grain weight and grain yield per plant. All the characters excepting stem girth and 1000 grain weight, showed a considerable range of variation. Grain yield per plant and number of grains per umbel showed high heritability and ': high genetic advance. This indicates that selection based on phenotypic performance could be of help in improving these characters. Stem girth, number of primary branches per plant and 1000-grain weight showed low heritability as well as low genetic advance. In this case we suggest the use of heterosis breeding for further improvement.

Abstract
Singh P., Chawla B.K. and Singh P. (1987): Multivariate analysis for yield and quality components in linseed. - Genetika, Vol. 19, No. 1, 73-78.
Fifty indigenous and exotic strains of linseed (Linum usitatissimum L.) were selected to measure the genetic divergence for 12 characters according to Mahalanobis D2 statistics. Analysis of variance revealed considerable variation for all the characters studied. All the genotypes were grouped into 14 clusters. Intra-cluster D2 value was highest for cluster I. Highest inter-cluster distance was observed between cluster VI and XI. Clusters X to XIV, with a single genotype each, were much more diverse than other groups. Days to first flower, plant height, number of capsules per plant, biological yield and harvest index were found to be important attributes for selecting genetically diverse types.
