Abstract
A method for regenerating soybean plants from cotyledonary nodes is disclosed. Soybean seeds are germinated on nutrient medium containing a cytokinin to produce a donor plant. The cotyledonary nodes of the donor plant are excised and divided into pieces. The cotyledonary node pieces are cultured on nutrient medium containing a cytokinin until callus tissue develops which contains shoots. The shoots are removed and rooted on nutrient medium free of exogenous hormone to form a plantlet.
