Abstract: In order to enlarge the extent of soya hybridization, to increase the range of variations and to create the new cultivar of high photosynthetic rate, of good quality and of high yield by means of somatic cell hybridization, we have used the cotyledon, leaf, stem and hypocotyl of soya as the material for tissue culture, have obtained the plantlets derived from callus for the first time and have harvested the seeds therefrom. This is the preparatory work for cell hybridization in further experiments.
