Correlation and Path Co-efficient Analysis for Yield and its Components in Rice (Oryza sativa L.)
Muhammad Saif-ur-Rasheed, Hafeez Ahmad Sadaqat and Muhammad Babar

Abstract: 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.
