Induced variability for yield and its attributing traits in cluster bean [Cyamopsis tetragonoloba (L. ) Taub] through gamma irradiation

Gamma ray is an effective mutagen which creates useful variability for crop like cluster bean where the natural variation is very meagre and creation of variability by conventional methods is cumbersome. In the present study, cluster bean cv. Pusa Navbahar was treated with different level of gamma r...
