The influence of allelic differences of Vrd1 and Ppd-D1 genes on winterhardiness, frost resistance, yield and its components was studied in recombinant-inbred F5 lines of Odesskaya 16/Bezostaya 1. From 9 to 15% differences in the resistance of recombinant-inbred lines were determined by alternative alleles of Vrd1 gene and 10-16% of Ppd-D1 gene. Interaction of vrd1 and Ppd-D1a alleles led to the higher winterhardiness and frost resistance of tillered plants during the winter. At the same time the significant increase of the period to heading, plant height and the tendency of yield reduction were revealed for vrd1 vrd1 Ppd-D1a Ppd-D1a lines when compared to the lines of Vrd1 Vrd1 Ppd-D1a Ppd-D1a genotype.
在敖德萨16号/别佐斯塔亚1号的重组自交F5代品系中，研究了Vrd1和Ppd - D1基因的等位差异对抗寒性、抗冻性、产量及其构成因素的影响。Vrd1基因的替代等位基因决定了重组自交系抗性9%至15%的差异，Ppd - D1基因的替代等位基因决定了10%至16%的差异。vrd1和Ppd - D1a等位基因的相互作用导致分蘖植物在冬季具有更高的抗寒性和抗冻性。与此同时，与Vrd1 Vrd1 Ppd - D1a Ppd - D1a基因型品系相比，vrd1 vrd1 Ppd - D1a Ppd - D1a品系抽穗期显著延长、株高增加且有减产趋势。
