Abstract

An efficient process employing cytoplasmic male sterility is provided wherein seeds capable of forming F.sub.1 hybrid Glycine max plants and restorer plants for the same simultaneously are formed in bulk in a single planting area and the seed harvest subsequently is segregated to form two substantially uniform seed assemblages. The parent soybean plants are provided with distinctly colored maternally-derived seedcoats wherein the genes for seedcoat coloration are homozygous dominant in one parent and homozygous recessive in the other parent. The resulting seeds are harvested in bulk and are separated on the basis of the soybean seedcoat coloration. Soybean plants resulting from the planting of the seeds capable of forming F.sub.1 hybrids upon self-pollination form seeds which substantially uniformly exhibit maternally-derived light-colored seedcoats in the F.sub.2 generation thereby enabling the grower to produce a substantially uniform soybean harvest. The other seeds formed in the initial planting area are capable of substantially uniformly forming restorer soybean plants in a subsequent planting.
