Genetic analysis of two rye interline crosses and a set of wheat/rye chromosomal additoin lines was performed to reveal the mechanism underlying wide variation range of alpha-amylase activity in sound grain.THe long arm of chromosome 6R was found to be responsible for increased enzyme synthesiis during late stages of triticale grain maturation.Only nuclear genes seemed to control alpha-amylase activity, as reciprocal crosses between rye lines showed no maternal effects.Low enzyme activity showed complete dominance over high level of its synthesis.Segregation ratios, observed in F2 and BC1 crosses, indicated that recessive alleles at two independent duplicative loci underline intensive alpha-amylase production.
