영문 초록

Segreating F₂ populations of seven wheat crosses were planted in Suweon and in Muan to investigate the regional variations in inheritance and heritabilities of heading date. Among seven F₂ populations, the crosses Chugoku 81×Centurk and Suweon 197× Chugoku 81 gave a 3:1 early to late ratios in F₂ suggesting a single dominant early gene in Chugoku 81. The cross Norin 16×Kanto 75 gave a 7:9 early to late ratio suggesting complementary gene action with lateness dominant. The crosses Strampelli× Chokwang and Suweon 197×Sinkwang gave a 9:7 early to late ratios suggesting complementary genes action with earliness dominant. The crosses Namkwang×Suweon 215 and Norin 4×Bezostaya gave a 1:15 ratio to suggesting duplicate gene action where lateness in dominant. Heading period of the F₂ population in northern Korea teas shorter than that in southern Korea. Broad sense heritabilites in the northern area were lower than that in the southern areas.
