Abstract In F1 diallel crosses the effect peculiarities of general and constant of specific combinational ability and their ratios within winter bread wheat, carriers of wheat-rye translocations and without them, according to index «weight of 1000 seeds». The sources of steady high general and specific combinatve abilities are distinguished: Smuhlyanka and Kryzhynka – the carrier of different wheat-rye translocations. The mentioned above cultivars are recommended to be involved in hybridization under conditions of steppes of Ukraine to improve the studied feature. Particular attention should be paid to the cultivar Smuhlyanka – carrier of 1AL/1RS translocation, which represents the largest selection values to create forms with high weight of 1000 seeds whereas it showed the best indicators of general and specific combinative abilities steady for years of study.
Key words winter bread wheat, wheat-rye translocations, combinative ability, weight of 1000 seeds
