  Analysis of variance indicated highly significant differences among the genotypes for all the traits studied except for number of branches per panicle. Covariance studies reflected significant to highly significant as well as negative differences among majority of character combinations. Broad sense heritability estimates for number of spikelets per plant, number of nodes per panicle and number of grains per panicle ranged from 41.20 to 48.20. Panicle length, spikelet number and number of nodes per panicle revealed significant genotypic correlation to number of grains per panicle. Among the characters studied, number of nodes per panicle depicted the highest direct and indirect contribution of 1.071 and 0.873 respectively towards number of grain per panicle. Path coefficient analysis demonstrated that for greater number of grains per panicle, number of nodes per panicle should be increased.

  Investigation of path coefficient analysis for yield and yield components in rice (Oryza sativa L.) was conducted involving 15 genotypes. Analysis of variance indicated highly significant differences among the genotypes for all the traits studied. Covariance studies reflected significant to highly significant as well as negative differences among majority of character combinations. Broad sense heritability estimates for productive tillers per plant, grain yield per plant and plant height ranged from 0.55 to 0.705. All the traits viz. total number of tillers, number of productive tillers, flag leaf area, straw yield, harvest index and fertility index except plant height revealed significant genotypic correlation to grain yield. Among the characters studied, harvest index depicted the highest direct contribution of 0.665 and fertility index show highest indirect contribution of 0.873 towards grain yield. Path coefficient analysis demonstrated that harvest index, straw yield and fertility index should be improved for the improvement of grain yield.

  The analysis of variance indicated highly significant differences among the genotypes for all the traits studied except thickness of the grain. Covariance studies reflected significant to highly significant as well as negative differences among majority of character combinations. Broad sense heritability estimates for length breadth ratio and length of the grain ranged from 46.20 to 49.10. Genotypic correlation of 1000 grain weight and breadth of the grain with grain quality were significant, while non significant association were observed between length of the grain, length breadth ratio and rice quality index at genotypic level. Among the characters studied, breadth of the grain depicted the highest direct contribution of 2.239 and 1000 grain weight showed highest indirect contribution of 1.143 towards grain quality. Path coefficient analysis demonstrated that for better grain quality breadth of the grain, 1000 grain weight and length of the grain should be maximized.
