Soybean Genetics Newsletter


Before hybrid soybeans can become a reality, two requirements should be satisfied: (i) an economical large-scale method of producing hybrid seed must be found, and (ii) heterosis for yield must exist. With the findings of genetic male sterility in soybeans (Brim and Young, 1971) interest has devel-oped in the potential productivity of hybrid soybeans. A method for produc-ing experimental quantities of hybrid soybean seed using genetic male sterility and green seed embryo was suggested by Burton and Carter (1983).
