A study was undertaken to find out the genetic variability and correlation between yield and other yield attributing characters of rice genotypes of Assam and Arunachal Pradesh. The experiment was conducted with fifty four genotypes grown during Wet season under transplanted condition in a randomized complete block design. Analysis of variance shows significance in all the traits indicating the presence of considerable amount of genetic variation among the genotypes. The traits like grain yield/plant and tillers/plant has high genotypic coefficient of variation and phenotypic coefficient of variation; while plant height and days to 50% flowering has high genetic advance. Plant height, leaf width and panicle length were positively and significantly correlated with yield. Tillers/plant and plant height has high direct effect on yield. Therefore, selection based on plant height and tillers/plant could be more effective in rice yield production of Assam and Arunachal Pradesh.
