Abstract
The differences between effects of homoeologous group 5 chromosomes on growth phases and agronomic characters were studied by using reciprocal substitution lines between a winter wheat cultivar with a high vernalization requirement (Mironovskaya 808) and one with lowvernalization requirement (Bezostaya 1), in which the presence of different recessive vrn alleles is supposed. The two cultivars and the substitution lines Mironovskaya 808 (Bezostaya 1 5A), Mironovskaya 808 (Bezostaya 1 5B), Mironovskaya 808 (Bezostaya 1 5D), Bezostaya1 (Mironovskaya 808 5A), Bezostaya 1 (Mironovskaya 808 5B),Bezostaya 1 (Mironovskaya 808 5D) were grown at 10 different sowing dates. The results showed that differences between the homoeologous group 5 chromosomes of Mironovskaya 808 and those of Bezostaya 1influenced the growth phases in addition to the impact by the genetic background and sowing date. We inferred from the analysis and comparison of their effect on vernalization response that vrn loci on these chromosomes influence growth phases. It is probably due to pleiotropic effects of the loci. The rare occurrence of significant interactions between group 5 chromosomes × sowing dates probably indicates independence of their effect. Agronomic characters were also markedly influenced by sowing date and the difference in backgrounds between Mironovskaya 808 and Bezostaya 1. A significant impact by at least two of the chromosomes on almost all studied characters was detected. The chromosomes affected the combined characters in the order5D>5B>5A and the positive value of the differences suggests that a content of Mironovskaya 808 chromosomes is more advantageous. It was possible to find certain indices in some agronomic traits, supporting the idea that the expression of some characters can also be connected to vernalization requirement and thus to the expression of the vrn loci. This supposition is most probable in the number of tillers and number of spikes. In some traits significant interactions occurred between homoeologous group 5 chromosomes × genetic background. Sporadic and low significance between homoeologous group 5 chromosomes × sowing dates suggest that the genetic effect of these chromosomes is independent of environmental conditions.
