%X An investigation was carried out at RARS, Bijapur and MARS, Dharwad during rabi 2007-08, using a total of 120 F6 generationlines derived from B กม B, B กม R and R กม R crosses along with 20 checks (varieties, existing B and R lines and parents) in RCBDwith 2 replications. The study aimed to assess the nature of association between yield and its component traits and the direct andindirect effects of yield component traits on yield. Character association studies revealed that plant height, number of leaves perplant, number of internodes per plant, panicle length, panicle breadth, number of primaries per panicle, test weight, number ofgrains per panicle and fodder yield per plant had positive association with grain yield per plant at both the locations (Bijapur and Dharwad). On the other hand, days to 50% flowering had negative association with grain yield per plant. The characters viz.,number of primaries per panicle and number of grains per panicle had the highest direct positive effect on grain yield. Hence, itwould be rewarding to lay stress on these characters in selection programme for increasing yield.
