Abstract:

Thirty Recombinant Inbred Lines (RILs) of F8 generation derived from Langulmota/Sambamahsuri were tested for variability of yield and yield attributing characters along with parents and three check varieties during kharif-2016, at the Instructional farm, Bidhan Chandra Krishi Viswa Vidyalya, Jaguli, Nadia, West Bengal. The lines S2, S28, S10, S24, S17 shown yield advantage of 4.78%, 4.58%, 4.1%, 3.48%, and 2.7% respectively as compared to both parents and checks. Lines S2, S10, S17, S5 and S3 shown yield advantage of 35.83%, 34.94%, 33.12%, 32.94% and 32.59% respectively as compared to best check variety only. Characters like number of florets per panicle, followed by number of grains per panicle, plant height at maturity, floret fertility (%) recorded high phenotypic and genotypic variance. High estimates of PCV and GCV was obtained for number of florets per panicle, number of grains per panicle, panicles per plant, panicle weight, 1000 grain weight and number of secondary branches per panicle. High heritability estimate was observed for all the characters except grain L/B ratio. High estimates of heritability coupled with high genetic advance were obtained for number of florets per panicle and number of grains per panicle and plant height. Thus, it may be suggested that these characters are predominantly controlled by additive genes.
