An experiment was carried out during Kharif, 2017-18 at Central Research Station, Masodha, (Faizabad), KVK, Narendra Deva University of Agriculture and Technology, Narendra Nagar (Kumarganj), Faizabad (U.P.) to study the simple correlation coefficients among 14 quantitative characters with 27 genotypes along with three checks in three replications using RBD (Randomized Block Design). Estimates of simple association coefficients among 14 quantitative characters estimated during 2017-18 displayed that Seed yield per plant exhibited highly significant and positive correlation with days to Maturity (0.985) and panicle bearing tiller per plant (0.989), tillers per plant (0.660), and panicle bearing tillers per plant (0.710), Seeds per panicle (0.843) characters showed significant and positive correlation with these traits. All the other characters under study also displayed highly significant associations with each other besides seed yield per plant. The characters included in the study viz., days to 50% flowering, days to maturity, plant height, number of seeds per panicle, panicle length, harvest index, number of tillers per plant, biological yield, number of panicle bearing tillers per plant, 1000-seed weight, Germination percent, Seedling length, Vigour index and Seed yield per plant.
