Isolation of High Yielding Early Mutants of Sesame (Sesamum indicum L.) Based on the Relationship Between Traits Governing Yield and Earliness

Sesame is a leading oilseed crop known for its quality edible oil and byproducts. Mutation breeding an effective means of creating new genetic variability as certain desirable traits like uniform maturity, non-shattering capsules etc., do not exist in nature..The present study aimed to isolate high yielding early mutants sesame on the basis relationship between governing yield earliness. Gamma-ray doses 300 Gy, 350 400 Gy combination treatments gamma-ray + EMS: 10 mM, mM were used this study. In M2 generation, putative with earliness isolated characterized individually nature association single plant maturing lines. Two viz., increased height at beginning flowering reduced days found have favorable effect reducing period increasing yield. Therefore, these two should be criterion selection achieving sesame. addition, ‘tri-leaf’ characteristic observed ‘early mutants’ led Early lines maturity can enable mechanical harvesting future cultivation. The selected may forwarded further generations utilized breeding.
