Abstract

Sesame is important oilseed crop. Due to fluctuation in the environments the yield and productivity badly affected in sesame. Present investigation is useful to develop the new varieties using stable genotypes as a parent in crossing programme. Therefore, sixty sesame genotypes with 3 checks, AKT-64, AKT-101 and PKV-NT-11 for eleven quantitative characters assessed at three environments in season summer 2018-19 to estimate the stability performance using Eberhart and Russel model (1966). The g x e (linear) interaction exhibited significance for the characters days to 50% flowering, days to maturity, plant height, number of capsules plant-1 and seed yield plant-1 and significant for number of branches plant-1. The environment + (G × E) remained highly significant for all traits excluding capsule breadth, length of capsule and oil content. Significance of environment (linear) constituent for all the traits checks the observations of broadly differing environments. Among sixty germplasm, genotype IC- 203884 (16) for days to 50% flowering and seed yield plant-1 (g) and genotype DS-46-3 (51) for number of capsules plant-1, number of seed capsule-1 and seed yield plant-1 (g) were identified stable.

Conclusion

As yield is prime character, the investigation determined that genotypes IC- 203884 (16), DS-46-3 (51) and IS-157-A (54) recognised as stable with high mean value for seed.
