None of these techniques are completely satisfactory from the standpoint of the plant breeder who on observing an F2 population asks himself, with respect to a particular character: "To what extent is selection likely to be effective?" What this plant breeder needs, is an early generation estimate of heritability. A method is presented below which offers the following advantages: (1) The estimate is made entirely on the basis of the FB and the backcross of the Fi to each inbred parent. (2) The estimating of nonheritable variance is unnecessary.
