title: Heritability estimates from four generations of a diallel cross of common wheat.
abstract: The heritabilities of 10 quantitative characters were studied on F1, F2, backcross, and selfed backcross generations of a five-parent diallel cross of common wheat grown at two locations. From this study it was found that (a) most of the characters in question were highly heritable, (b) the heritabilities estimated by regression and variance component methods were more or less the same (r=0.84** to 0.95**), and (c) the heritability of some characters was affected by location or by generation; in one case only (1000-kernel weight) was the heritability of the character affected by both.
