ABSTRACT

High heritability was estimated for all the characters. Phenotypic Coefficient of Variation (PCV) was higher than Genotypic Coefficient of Variation (GCV) for all the characters studied, indicating the influence of environment on the characters. High GCV was estimated for plant height, stem length, seeds per panicle, L/B ratio, moderate for 1000 seed weight, flag leaf length, leaf breadth, days to flowering ,seed/plant and days to maturity, whereas low was estimated for panicle length. High genetic advance was estimated for plant height number of panicles per plant, stem length, L /B ratio, 1000 seed weight and number of seeds per panicle, however moderate for leaf breadth and days to flowering.
