Molecular heterogeneity was studied in 20 spring triticale accessions by using ISSR- and RAPD-markers, which allowed the studied material to be grouped according to the degree of genetic relationship and to choose genetically distant parental pairs for crosses to obtain heterotic hybrids. Expression of heterosis of F1 triticale hybrids was studied. Evaluation of the degree of parents genetic divergence on the heterosis level of F1-hybrids revealed that increase of genetic distance values between parental components leads to higher probability of obtaining heterotic hybrids.

The article describes differences in a response of linseed cultivars of a different genetic and geographical origin to a set of ecological factors. Variability in productivity traits was revealed to be determined in most cases by a genotype and its interaction with growing conditions. The genotype and environmental conditions exert an equal effect on oil accumulation in seeds and its qualitative composition. Based on the data obtained from the linseed collection, the most ecologically stable genotypes, displaying steadily high seed productivity in combination with high content and quality of oil, were selected.
