Effect of 60Co and ethyl methane sulphonate on growth and fruit development of capsicum annum

Flowering was delayed to a remarkable extent following mutagen treatment both in M1 and M2 generations. Gamma radiation was found to be more effective as compared to E.M.S. in delaying flowering. Weight of 100 dry fruits increased with an increase in dose of radiation. No significant effect of E.M.S. in M1 and M2 generations was observed. Mohol-9, a variety of Capsicum annuum L. produced the heaviest seeds out of all the varieties treated with 100 KR gamma rays while C.A. 452-1 had comparatively heavier seeds than other varieties, when treated with 0.2% E.M.S.
