摘要：
Genetic analysis of three semi-dwarf genotypes of rye (Secale cereale L.) - 'Moskowskij Karlik', 'Gulzow Kurz' and 'R 18', which were shown to be insensitive to applied gibberellic acid (GA3), has been carried out by using a seedling test. It could be demonstrated that all of the three genotypes are carrying recessive alleles for GA-insensitivity. Whereas the alleles of 'Moskowskij Karlik' and 'R 18' seem to have the same locus on chromosome 5R, the GA-insensitivity of 'Gulzow kurz' is governed by a different gene, most probably located on chromosome 7R. The relationship between the genes (alleles) for GA-insensitivity and semi-dwarfness, including the symbolization of the Gai-genes as well as their utilization in rye breeding is discussed.
