INHERITANCE OF GLUCOSE PHOSPHATE ISOMERAS E, AWNEDNESS, HAIRY GLUME, AND GROWTH HABIT IN AEGILOPS SPELTOIDES AND AEGILOPS AUCHERI

Polymorphism for GPI (glucose phosphate isomerase), awnedness, hairy g lume, and growth habit (spring-winter) was found in populations of Aeg ilops speltoides Tausch and Ae, aucheri Boiss. Populations also differ ed in degree of self-pollination. Segregation analysis in F-2 showed m onogenic control for the first three traits and digenic control for th e fourth one. Three alleles of the Gpi1 locus were described. The domi nance of awnedness was first demonstrated for Triticum and Aegilops ge nera. All traits studied were inherited independently. Segregation at the awl (awnless) and Hg (hairy glume) genes significantly deviated fr om the monogenic ratio in self-pollinated F-2 progeny. Results are dis cussed in the context of gene location in common wheat.
