The present study was carried out at Agricultural and Horticultural Research Station, Ponnampet, University of Agricultural and Horticultural Sciences, Shivamogga during 2015. The experimental material comprised of 15 advanced varietal lines including existing variety as check. Mean performance of individual rice genotypes revealed that the days to 50% flowering found to vary from 85.00 days to 114.50. Plant height was found to vary from 59.84 cm to 91.33 cm with average height of 75.42 cm. Number of panicles per m2 area ranged from 304.52 (IET-1912) to 580.80 (IET-1902) with mean of 432.21 panicles/m2 area. The genotype IET-1912 produced maximum grain yield (5172.60 kg/ha) and found to be 20.77% superior in grain yield than local check Tunga (3096.09 kg/ha) followed by IET-1914 (5059.61 kg/ha) which found 19.64% superior, whereas IET-1908 was found to be 3.74% inferior in grain yield (2722.42 kg/ha) than local check. Analysis of variance revealed highly significant sum of squares due to genotypes for all the characters indicating existence of ample variability among the genotypes. The traits such as plant height, number of panicles/m2 and grain yield which showed high heritability coupled with high genetic advance could be used as selection criteria for their improvement since these are governed by additive gene action. The traits like plant height and days to 50% flowering could be used as indirect selection criteria for their simultaneous improvement.
