Genetic analysis of a cross-pollinated species, Secale cereale L., for the character with polymorphic genetic basis.

Theoretical basis and an algorithm of calculations for frequencies of genes and genotypes in the population of species with obligate cross-pollination under assessment for the character of polymorphic genetic basis are proposed. Use of four rye populations and the F1 and F2 from their crossings allows to determine genetic control of beta-amylase spectrum through identification of two genes, establishment of the allele number in each gene, and showing the linkage between beta-Amy-1 and the gene for self-incompatibility S2.
