Analysis of variance of forty upland genotypes indicated that all the genotypes were significantly different, with respect to most of the characters, except number of tillers plant-1, effective tiller plant-1 and grain yield panicle-1. Characters like grain yield plant-1, flag leaf area, grain yield panicle-1, plant height, 1000-grain weight and number of grains panicle-1 had recorded light to moderate PVC, GCV, heritability and genetic advance as per cent of mean. grain yield plant-1 had a significant and positive association with number of tillers plant-1, effective tillers plant-1, plant height, panicle length, number of grains panicle-1, grain yield panicle-1, flag leaf area and 1000-grain weight both at genotypic and phenotypic level. Path analysis revealed that all characters had positive direct effect on grain yield plant-1, except 1000-grain weight. Present study revealed that grain yield panicle-1, number of grains panicle-1, flag leaf area and plant height should be given more weightage during selection for increasing grain yield in upland rice.
