The Giemsa staining technique was used to study the chromosome morphology of the populations Belozernaya [White-grained], Belozernaya bez voskovogo naleta [White-grained Waxless] and Stal' [Steel], and of the inbred lines obtained from them. In the initial populations differences were found in the frequency of dark-stained bands on the metaphase chromosomes; the most variable were the bands of centromere and intercalary heterochromatin. The populations contained plants in which some homologous pairs of chromosomes were heteromorphic, through in the lines derived from them all the homologues were homomorphic.
