Studies on induced chlorophyll mutation in sesame (Sesamum indicum L.)

Abstract

                                The effectiveness and efficiency of gamma rays and EMS in relation to chlorophyll mutations were studied in two varieties of sesame (Sesamum indicum L.) viz. SVPR 1 and CO1 in M, generation. Four types of chlorophyll mutants namely xantha, chlorina, striata and Xantha viridis were observed. Xantha viridis was observed in maximum proportion followed by chlorina and striata in both the varieties. Gamma rays was found to be more efficient and effective than EMS in both the varieties. The effectiveness and efficiency of both the mutagens was more in SVPR1 than CO 1.

Key words : Mutagen, Chlorophyll mutant, Mutagenic effectiveness and Efficiency.
