BINATIL-2: A GAMMA RAYS INDUCED MUTANT VARIETY OF SESAME (Short communication)
Seeds of local sesame variety T-6 were irradiated with gamma rays and grown as M1 during Kharif-I 2002. The yield potential of two M6 mutants, SM-5 and SM-12 was evaluated through different trials in some sesame growing areas of the country during 2007 to 2009. Results showed that mutant SM-12 produced the highest seed yield in all the locations and years. Mutant SM-12 also produced the highest number of capsules/plant. Average seed yield of SM-12 over the locations and years was 1531 kg/ha which was 6.2 and 11.2% higher than two popular check varieties, Binatil-1 and BARI Til-2, respectively. Binatil-1 and BARI Til-2 produced the seed yield of 1446 and 1377 kg/ha, respectively. Results of yield trials carried out across the country indicated SM-12 was found suitable and thus National Seed Board of Bangladesh registered SM-12 as Binatil-2 in 2011 for commercial cultivation in Bangladesh.
