Abstract:

Five hybrid families were analysed that has been obtained from the crosses between the varieties Vulkan R1R3, Veselovskiy R2, Drossel R1, Orion R1 and Cameras R1. It is established, that all the parental forms carry the R genes in the simplex state. In the progeny from the cross Vulkan x Cameras the observed segregation was in agreement with the theoretically expected ratio 3R1R33R11R31r. In the progenies from the crosses Veselosvkiy x Cameras R2 x R1 and Veselovskiy x Agra R2 x r type Veselovskiy x Drossel and Veselovskiy x x Orion an excessive proportion of recessive forms was observed, while the proportion of hybrids with the R1R2 and R2 genotypes was below the theoretically expected one.
