Sesame is the leading oil seed crop. Creation of new genetic variability is prerequisite for any crop improvement
programme. The white seeded sesame variety VRI 3 was subjected to induced mutation using gamma ray and
combination treatments (300 Gy + 10 mM EMS, 350 Gy + 10 mM EMS and 400 Gy + 10 mM EMS). From M2
generation, mutants were identified for multiple capsules per axis, closed capsules, tri leaf, determinate nature, early maturity, clustered flowering, profuse branching, high number of capsules, variation in capsule length and plant height etc. These mutants have to be forwarded to next generation to identify their true genetic behavior for further utilization in the future breeding programmes.
