Abstract:

The experiment was carried out with a RIL (F7) population (100 lines out of 189 lines available) raised by crossing between Gobindabhog and Satabdi. They were grown in the Regional Research Sub- Station, Sekhampur, and Nadia. Out of eleven quality parameters, kernel breadth, ratio of length and breadth after cooking, elongation ratio, aroma and colour of kernel possess significant difference between two parents. Similar set of alleles for 100 SW is present in both parents as evidenced from the fact that 85% of RILs was within the narrow range of two parental values. Like Basmati, Kernel elongation ratio after cooking of Gobindabhog can be utilized as donor parent for improving this character in other rice too. Amylose contain (AC) in both the parental genotypes is 20-15% which may be called as intermediate category. However, instead of a similar major locus of chromosome 6 (amy6) for mylase present in both parents, RILs showed significant variation ranges from 17% to 22%. It is mainly due to contribution of favourable alleles of Gobindabhog present in another minor QTL, amy3, of chromosome 3. Betaine aldehyde dehydrogenase 2 (BAD2) gene is a major gene controlling aroma in Gobindabhog probably with one or two minor gene/s as evidenced from aroma analysis of RILs as well as their status of BAD2 gene. Among the hundred lines, RIL85 was selected as the best semidwarf high yielding line with higher kernel length, cooked kernel elongation ratio, low intermediate ASV, above 20% (by percentage of starch) amylose and aroma.
