The paper presents results of studies on the inheritance of plant height in four short-stem genotypes of rye selected from genotypically different collection materials.Short-stem genotypes P-2, P-9, P-30 and P-52 were crossed to a tall-stem inbred line Uniwersalne 145 (S17).The genotype P-2 was additionally crossed to a related, but tall-stem line P-2 W.In each cross combnations six generation -P1, P2, F1, F2, B1 (F1 x P10 and B2 (F1 x P2) - were examinaed.Distribution of plant height in hybrid generations haad a continous character, which indicated a polyugenic determination of short stem an all "P" genotypes under study.Results of the genetic analysis showed a significant role of additive, dominance and epistatic gene action in genetic determinatin of short stem in th "P" genotypes.
