A method for Production of Experimental Quantities of Hybrid Soybean Seed

Abstract

Abstract

The production of F1 seeds is difficult in soybeans [Glycine max (L.) Merr.]. Hand pollinations are tedious and time consuming, and each successful pollination only produces one, two, or three seeds. A method is suggested herein for producing experimental quantities of hybrid soybean seeds by the use of two traits, genetic male sterility (ms1ms1 or ms2ms2) and green seed embryo (d1d1d2d2). The green seed embryo shows through a yellow seed coat to give the soybean seed a green phenotype that can be easily recognized. Male-sterile maintainer lines marked with green seed embryos would be used as female parents. The male parent could be any cultivar (or strain) that has a yellow seed embryo (D,1-, D2-, or both) and that flowers synchronously with the female parent. Cross-pollination would be effected by insect vectors in blocks where the male and female lines were inter planted. Yellow seeds harvested from green-seeded, male-sterile plants would mark F1 hybrid seeds.
