| Abstract: | Summary Rye chromosome constitution and stability in a series of plants of G2 and G3 generations obtained after the cross between hexaploid triticale and durum wheat (F1: 2n=5x=35; genomes AA BB R) are studied using the zymogram phenotype expression for the following isozyme marker genes: Mdh-2c1 (1R), Cpx-c2 (2R), Got-3-c1 (3R), Pgm-c1 (4R), Est-c6 (6R), Got-2-c1 (6R), Acph-c1 (7R) and Got-1-c1 (7R). The results were corroborated using C-banding in a sample of the plant population studied and make clear the utility of biochemical methods in quick cytogenetic analysis. From the results, a different rate of transmission for each rye chromosome is inferred. |
