Abstract:
Sesame is an important edible oil yielding crop grown worldwide. Due to its self-pollinated nature and lack of variability, conventional breeding techniques have not so fruitful results in development of improved genotypes. An alternate solution is use of mutagenesis. Therefore, an experiment was conducted at the research farm of RBS College, Bichpuri, Agra to study the response of mutagens on spectrum and frequency of chlorophyll and other viable mutations in sesame. In M2 generation, the highest chlorophyll mutations were recorded in 25kR followed by 0.2%HA, 0.2%HA+ 0.2%MH and 0.2%MH.The leathery leaves had high frequency followed by xantha, albina and chimera. The stem types mutations were recorded highest in 0.1%HA+0.1%MH followed by 0.2%HA+0.2%MH, 0.2%MH, 20kR and 0.1%HA. The lowest frequency was recorded in 25Kr. Bushy stem were observed highest and lax branched as lowest. The leaf type’s mutants have highest frequency in20kR followed by 15kR+0.1%HA, 30kR and 60kR.Narrow leaf mutants were found highest followed by thick leaves, elongated leaves bunchy and long petiole. The highest frequency of flower and capsule type mutants were recorded in 30kR followed by 60kR, 20kR+0.1%HA, 0.1HA and 45kR. The mutations rate was maximum in 60kRfollowed by 20kR+0.1%HA, 30kR and 20kR (reduced with dose of mutagens) 0.1%HA+0.1%MH was observed as most effective mutagens followed by 0.1%HA, 0.2%MH and 0.1% MH. Moreover, 0.1% HA+0.1%MH also found most efficient and the efficiency of 0.2% HA+0.2%MH, 60kR, 15kR+0.1%MH and 20kR+0.1%HA was observed in decreasing order.
