[Analysis of dominant spring mutations in rye].
The dominant mutant genes responsible for the spring habit were studied in seven rye plants according to the developed scheme of two-step crosses and analysis of the F2 progeny. The genotypes with a particular genetic formula (heterozygote) were obtained by crossing the studied plants with the winter rye Korotkostebel'naya 69 carrying the recessive genes that control the winter habit of plants. Heterozygotes yielded by different combinations were crossed with each other. The F1 hybrids were either self-pollinated to obtain F2 progeny or crossed with the winter rye. Analysis of the progeny suggests that all seven plants carry the same gene.
