- Abstract
A study was undertaken to find out the genetic variability and correlation between yield and other yield attributing characters of rice genotypes in upland ecology. The experiment was conducted with twenty two upland genotypes grown during Wet season under direct seeded condition in a randomized 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 plant height, ear bearing tiller and yield has high genotypic coefficient of variance, phenotypic coefficient of variance and genetic advance. Plant height, ear bearing tiller, panicle length, panicle weight and length were positively and significantly correlated with yield. Plant height and grain per panicle, 50% flowering, thousand grain weight and ear bearing tiller has high direct effect on yield. Therefore, selection based on plant height, 50% flowering, thousand grain weight and ear bearing tiller could be more effective in upland rice.
