Studies on Genetic Characteristic of Upland Rice (Oryza sativaL.)

The considerable amount of genetic variability was exhibited among the accessions of local collection obtained from natural habitat of Eastern U. P. (India) under the UPCAR project. High genotypic and phenotypic coefficient of variation, heritability and genetic advance as per cent of mean was recorded for total number of grains per panicle, filled grains per panicle, number of effective tillers, leaf width and grain yield per plant. Positive and significant association was recorded by days to 50% flowering, days to maturity, leaf length, leaf width, filled grains per panicle and total number of grains per panicle among themselves and also with grain yield per plant at genotypic and phenotypic levels. Days to maturity, plant height, number of filled grains per panicle and test weight exhibited positive direct effect both at genotypic and phenotypic levels.
