This experiment is intended to reveal the relationship between F2 individuals and F3 lines in important agronomic traits to clarify the effectiveness of early generation selection in the wheat breeding program. Correlation analysis between F2 individual and F3 lines indicated that the plant height, heading date and winter hardiness may be improved through early generation selection and with remarkable genetic advances by selection. Early generation selection for yield potential varied depending upon the cross combination tested, but, generally speaking, correlation coefficients estimated between F2 and F3 generation, heritabilities and estimated genetic advances were low enough to conclude that its selection would be neglible in early generation
