Thirty seven rice germplasm were evaluated to assess genetic variability, heritability, genetic advance, correlation and path coefficient analysis for 17 quantitative characters. The experimental results concluded that TP-29632, followed by TP-30015, TP-29637, SHUATS DHAN-2 and TP- 30025 was found to be superior in grain yield among 37 exotic rice genotypes. IRRI-5 (TP-29632), IRRI-10 (TP-30015) and IRRI-21(TP-29759) recorded early maturity among 37 genotypes. Grain yield per hill was positively and significantly associated with flag leaf width, number of tillers per hill, number of panicles per hill, number of spikelets per panicle, number of filled grains, grain weight, biological yield, harvest index at both genotypic and phenotypic levels. Biological yield, harvest index, number of panicles per hill, plant height, flag leaf width recorded positive direct effect on grain yield per hill at both phenotypic and genotypic levels.
