Gamma irradiation effect on yield and yield attributing traits of sesame (Sesamum indicum L.) In M1 generation

Abstract

Sesame (Sesamum indicum L.) variety Rama and Tillotoma were exposed to different doses viz. 250, 300, 350, 400 and 450 Gy of gamma rays from Bhaba Atomic Research Centre (BARC) and grown (along with control) during pre-kharif 2015 in split plot design at University experimental farm Visva-Bharati, to study their effect on various characters like plant height, number of capsule per plant, number of branches per plant, days to first flower, days to 50% flower, flower duration, number of seeds per capsule, capsule length, days to maturity, 1000 seed weight (gm), and yield per plant. In M1 generation the results revealed that there was reduction and also amplification at higher doses compared to lower doses for the studied characters. The results were obtained in the present study clearly indicate that different doses of gamma rays can be effectively utilized to create variability for various quantitative traits of the crop.
