The present investigation was undertaken with the objectives to assess variability, heritability, genetic advance and genetic advance as percentage of mean (GAM)in 11 advanced recombinant lines of Kalanamak rice for fifteen quantitative traits. Trials were conducted for two seasons during wet season of 2016 and 2017 at Norman E. Borlaug Crop Research Centre (NEBCRC), G. B. Pant University of Agriculture and Technology (GBPUAT), Pantnagar, Uttarakhand in a Randomized Complete Block Design (RCBD) with three replications with the spacing of 20 cm × 15 cm and the recommended cultural practices were followed. The data were analyzed for using OPSTAT statistical software. Over the year high GCV and PCV was observed fortest weight (23.36 g and23.82 g) and grain yield (21.28 g and 21.88 g). Highest heritability was observed for weight of 1000 grains (96.02%) while lowest heritability was observed for days to maturity (27. 34%). Genetic advance as percentage of mean was observed highest for test weight(47.20 %) and lowest for days to maturity (1.01%). High heritability coupled with high genetic advance as percentage of mean was observed for test weight(96.20%& 47.21%) followed by stem thickness (95.36%& 24.60%) and yield (94.55%& 42.62%) indicating their usefulness in indirect selection to improve yield.
