Abstract:
In order to understand the nature and extent of variability and association of various quantitative
characters with grain yield, a field experiment was conducted with 45 short duration rice genotypes at the
Rice Research Station, Moncompu. The environmental influence on the different traits was evident from the
phenotypic coefficient of variability being higher than the genotypic coefficient of variability. Characters
such as plant height, flag leaf area, panicle exsertion, number of grains per panicle and grain yield exhibited
moderate to high heritability and genetic advance. Grain yield was found to be positively correlated both
at genotypic and phenotypic level with number of productive tiller's per hill, plant height, flag leaf area,
panicle length anil number of grains per panicle.
