The present study investigated the variability and correlations in rice. In present investigation, 50 genotypes of rice were grown in randomized block design with three replications accommodating each genotype in 4 m long single row plot spaced 30 cm apart. Observations on five competitive plants for 17 traits were recorded. The grain yield per plant showed positive and significant correlation with harvest index (;), hulling (;), number of effective tillers per plant and panicle length in E-I and harvest index, biological yield per plant, milling (;) and IOO-seed weight in E-ll. The path coefficient analyses revealed that harvest index and biological yield per plant were the most important traits contributing towards grain yield per plant in rice. Practical utility of the findings in improving grain yield of rice h.as also been discussed.
