Abstract:
The experiment was conducted during Kharif 2011 and 2012 at Agricultural Research farm, R.B.S. College, Bichpuri, Agra on the variety Gujarat Til-1 variety of sesame. The seeds were treated with different doses of gamma rays at CIMAP Lucknow, U.P and with different chemical mutagen at laboratory of R.B.S. College, Bichpuri, Agra. The evaluation of phenotypic variability, heritability and genetic advance is important for both plant breeders and germplasm curators to optimize the use of the variability available. Analysis of variance revealed significant difference for all the characters studied except test weight. The highest GCV and PCV were observed for the characters viz. number of capsule per plant, seed yield per plant and number of seed per capsule. High heritability was recorded for days to maturity, seed yield per plant, and number of capsules per plant, indicating that these characters are controlled by additive gene effect and phenotypic selection of these characters would be effective for further breeding purpose.
