Comstock and Robinson have given a statistical model for the isolation of the components of genetic variance in populations of biparental progenies. Their model has made possible the construction of one for self-pollinated progenies to be applied to the method of small grain breeding, wherein large numbers of bulked F2 and F3 progenies are tested for yielding ability. Inasmuch as the genetic variance of high yielding progenies will be due to both additive and non-additive genetic effects, it is important that these effects be separated.
