Extent of Genetic Variation in Indigenous Scented Rice Varieties of Assam

Forty indigenous scented rice varieties of Assam (locally known as Joha) including an introduction from Thailand were screened for the extent of genetic variation for yield and yield attributing traits, and for a few biochemical parameters. The results indicated that there was considerable variation among the varieties for all the traits. The estimates of genotypic and phenotypic coefficients of variation were found to be high for grains per panicle, 100 grain weight, flag leaf area, grain yield per plant, effective tillers and biochemical parameters studied.
