Soybean Genetics Newsletter


Tissue culture methods may benefit soybean breeders if whole plants can be differentiated from aneuploid, mutated, fused, or haploid cells. However, in order to realize this potential, it must be possible to derive plantlets from previously undifferentiated tissues - and ultimately from masses of callus cells. This report summarizes the information we obtained concerning adventitious budding from soybean tissues (Kimball and Bingham, 1973), early stages of embryo formation within masses of callus cells, and actual differentiation of plantlets from callus tissue.
