SYNOPSIS. Mean F2 grain and fodder yields of single crosses were 73% and 78% of the Fi, respectively; for double crosses they were 85% and 87%. Advanced generation seed, in the absence of selection, reaches its minimum of. productivity in the F3 when produced by sibbing whereas by selfing it continues to reduce until complete homozygosity is reached. Application of Wright's prediction formula for F3 hybrid performance is restricted to populations in which all component lines are equally represented.
