[Genetic composition of the short-stem rye populations (Secale cereale L.) for secaline genes].

Genetic composition for secaline genes was studied in four short stem rye populations (Bolgarskaya korotkostebelnaya, Gnom 1, Gnom 2, and Gnom 3) using the methods of classical hybridological analysis and population genetics. Eight, three, and four alleles of the genes Sec-3, Sec-2, Sec-1 correspondingly have been revealed in the studied populations. The frequencies of the specific alleles in each population were determined. The allele transmission to the next generation is restricted through the linkage of the secaline genes with the genes of self-incompatibility, S1 and Z, located on the same chromosomes as the secaline genes.
