The purpose of this study was to describe the association between grain yield and its components. The experiment was conducted in a randomized complete block design with three replicatsions. Results of analysis showed that similar trends were observed for genotypic and phenotypic correlations and in most cases, the value for genetic correlation was greater than phenotypic value. 100-seed weight revealed the greatest positive phenotypic correlation and plant height as well as 100-seed weight showed the greatest genotypic correlation with seed yield per plant. Path analysis using genotypic correlation coefficients pointed out that 100-seed weight, number of pods per plant, number of nodes per main stem and number of clusters per plant had the greatest positive direct effects on grain yield per plant, respectively. These traits included important factors determining seed yield in concerned genetic materials.
