Abstract
RiCENT studies on a number of characters of soybeans have been directed toward estimation of heritability, that is, the fraction of variance in phenotypic expression that arises from genetic effects. However, the different methods employed do not necessarily estimate the same thing. For example, variance and regression methods of estimating heritability of F2 plant differences estimate the same thing only if all gene effects are additive. The nature of the selection units (plant, plot, mean of several plots, etc.) and sampling errors also influence greatly the magnitude of heritability estimates. Therefore, any meaningful comparison of the estimates obtained in different situations must include a careful evaluation of the methods and materials employed
