The present investigation has been undertaken in sweet corn to carry out the combining ability analysis of yield and yield contributing characters. Eight divergent parents were selected and crossed in diallel fashion excluding reciprocals during kharif, 2010. The resulting 28 crosses along with parents and a standard check Sugar 75 and Madhuri were evaluated in Randomized Block Design replicated thrice, during rabi, 2010-11 at Agricultural Research Institute, Rajendranagar, Hyderabad. The data were collected on days to 50 % tasseling, days to 50 % silking and days to maturity, plant height, ear height, ear length, ear girth, number of kernel rows per ear, number of kernels per row, green cob yield, green fodder yield, 100 kernel (dry) weight and seed yield (wet) per plant. Path analysis studies revealed that highest direct effect on seed yield was exhibited by green cob yield followed by ear length appeared to be the main factor for their strong association with seed yield (wet) and other traits like days to 50 % silking, green fodder yield, sugar content in kernel and number of kernels per row also showed positive direct effect. Most of the traits showed their positive indirect effect through plant height, ear height and ear girth. Whereas, sugar content in kernel has showed its indirect positive effect through days to 50 % silking and days to maturity.
