Summary
Protoplasts were isolated from leaves of a single plant of Vigna aconitifolia, a drought resistant grain legume. The protoplasts regenerated and formed colony and calli from which 50 entire plants were regenerated and transferred to field conditions. Only 7 plants survived upto maturity and they flowered and produced pods with seed. The protoplast derived plants showed variation in important characters. Two groups of characters (one with 7 sets and another with 6 sets) were studied in the protoclones. In first group protoclones showed variations in seed germination, maturity age, pod length, pod and seed colour, number of abortive seed per pod and response to field rots, however, not much difference was recorded in pollen stainability and meiotic behaviour in these protoclones. In second group analysis of variants showed significance difference for plant height, rachis-length, length and breadth of mature odd leaflets, seed per pod and weight of seed. The results indicate that protoplast can be source of variation in this crop. However, detailed biochemical and genetical analysis of protoclones are required.
