This paper presents the results of the research of physiological characters of rooted cuttings of eight black poplar clones (4 Populus x euramericana and 4 Populus deltoides) in three field experiments on different soil types (humofluvisol, fluvisol f. loamy and fluvisol f. sandy). Physiological characters are net photosynthesis, dark respiration and leaf area. At the end of the vegetation period, the main plant growth elements were measured: diameter, height and biomass. The results of the research physiological processes of poplar clones showed a high interclonal variability of most elements and processes of species under study. The statistically significant interaction genotype x environment, in the greatest number of characters, indicates the different reactions of clones to the site, i.e. soil type. A strong genetic correlation with the elements of growth and biomass was shown especially by leaf area.
Key words: poplar clone, physiology, variability, genetic and phenotypic correlation

Used in this study were seven divergent cabbage cultivars, which we crossed using the complete diallel cross method. The traits we analyzed are important for further selection and were actually chosen based on this. The study’s results showed the traits to be significantly divergent, which represents a significant source of variability for the next cycle of selection. The predominant mode of inheritance of head masss and the edible portion of the head was superdominance. Variation of these two traits was prominent in both the parents and the hybrids, the primary reason being the differences in earliness of maturity. Yield once again proved to be a complex trait, varying in the parents and the hybrids alike. The variability of yield was much larger in the hybrids than in the cultivars. Superdominance occurred 23 times.
Key words: cabbage, inheritance, yield, yield components

Fifty wheat genotypes from different selection centers of Yugoslavia and world were analyzed. The experiment for this investigation was performed in a randomized block design in three replications on the experimental field of the Center for Small Grains, Kragujevac and during two year which differed in climate conditions. The 60 plants of each cultivar were analyzed. The protein content was analyzed by Kjeldahl method, and sedimentation value by Zeleny method. The results were calculated by analysis of variance, and components of variance (genetic, interaction, environment, phenotypic) were calculated from analysis of variance. Heritability was calculated as a ratio of genetic/phenotypic variance. High significant differences for grain protein content and sedimentation value at all investigated cultivars were established. High values for grain protein content from 14.4 % in Jugoslavija cultivar to 18.1 % in Hart cv., and sedimentation value from 25.5 ml in Brock cv. and Florida cv. to 70.5 ml in Bankut 1205 cv. were established. The broad-sense heritability of grain protein content was low (h2=33.2%), and of sedimentation value was high (h2=90.0%). The highest percentage of the whole phenotypic variability, was assigned to the cultivar/year interaction (58.54 %), while only 16.46 % were assigned to genetic factors. Higher impact of genotype (81.5 %) than environment (17.9 %) for the sedimentation value was found by phenotypic variance analysis.

Modern breeding programmes on new maize hybrids development require, among other studies, the investigation on the mode of cob diameter inheritance, nature of gene (additive, dominant) action, as well as, combining ability for this trait. The mode of this trait inheritance was performed by the analysis of diallel crossings of the following six maize inbred lines: ZPA2/11, ZPL619/1, ZPA82/9, ZPL73/20, ZPL300/1 and Mo17RfcHt. Analysis of variance of combining ability indicates highly significant difference for general (GCA) and specific (SCA) combining ability. The GCA/SCA-ratio of 5.59 points to a greater share of additive than dominant genes. These results are favourable from the aspect of selection, since additive genes can be fixed in the succeeding generations. Negative values of GCA of inbreds ZPA2/11 and Mo17RFcHt are important for development of new hybrids with smaller cob diameter and higher shelling %. On the other hand, positive estimates of GCA of the inbreds ZPA82/9 and ZPl73/20 result in greater cob diameter. The positive values of SCA were detected in the combinations ZPA2/11 x ZPL619/1 and ZPL73/20 x Mo17RFcHt. Analysis of variance indicates that the role of both, additive (D=7.73) and dominant (H1=5.11) components, was significant, but considering all combinations of crossings, additive one was more important in cob diameter inheritance. The estimate of H2/4H1=0.21 indicates that dominant and recessive genes are not symmetrically distributed in parents. Frequency of dominant alleles (u=0.72) is greater than of recessive alleles (v=0,28). Considering all combinations of crossings, the computed estimate of the average degree of dominance points out to partial dominance.
