Abstract: Rice is integral to the livelihood of billions of individuals over the globe. Perhaps the oldest domesticated grain crop of the world. It is grown in 26 states and 7 Indian territories of India. Yield has been always the main criteria for selection during a breeding programme. So by considering the following aspect the current study was conducted with 100 traditional rice accessions at in randomized block design (RBD) with 2 replications during Kharif 2018 with the objective to find out traits that are directly related to yield which can be selected during breeding programme by association analysis. For path and correlation coefficient analysis data was statistically tested to estimate different descriptive statistics Correlation study indicated that “per plant grain yield had positive and significant correlation with grain length, panicle number, thousand seed weight, panicle length, and flag leaf width where as in path coefficient analysis thousand seed weight, grain length, milling%, plant height, panicle number per plant, flag leaf width and panicle length demonstrated direct and positive effect with per plant grain yield.
