GENETIC-ANALYSIS OF EFFICIENCY OF TRITICA LE ANTHER CULTURE IN-VITRO

Androgenic triticale lines, obtained by in vitro cultivation, and thei r hybrids from diallelic crosses were compared to determine efficiency of induction of neoformations in F1 hybrids with different expression of productivity traits. The heterotic effect on quantiative traits wa s evaluated in triticale hybrid plants obtained from the cultivated li nes. It was demonstrated that genetic control of induction of calluses and embryoids is mainly determined by overdominance. Lines with the m aximal number of dominant alleles of genes controlling the increase of the studied trait were revealed.
