Abstract


A field trial was conducted during 2013 to evaluate 09 sesame genotypes (Pr -122, Pr- 126, Pr-135, Pr-147, Pr-68, Pr-24, Pr-167, Pr-70, Sehwan-II) for estimating yield and its associated characters keeping the 10th S-17 as check variety. Three replications under Randomized Complete Block Design were done. The seed yield plant-1 was highly significantly correlated in a positive manner with days taken by the genotypes to bear flowers (r=0.645**), number of branches produced by individual plant (r=0.353**); number of capsules on plant basis (r=0.368**), yield harvested from each plot (r=0.362**) and negative but nonsignificantly correlated between seed yield plant-1 and plant stature (r= -0.094NS) and seed index (r= -0.077NS). Regression analysis suggested that 41.6% variation in seed yield plant-1 was caused by days to flowering, 13.50% by capsules plant-1, 13.1% by yield plot-1, 12.5% by branches plant-1, 0.90% by plant height, 0.6% by seed index and 0.1% by days to maturity.
