The present investigation was undertaken in sweet corn to carry out the combining ability analysis for sugar content in the ker
nel. Eight divergent parents were selected and crossed in diallel fashion (Griffings Method-II, Model-I) excluding reciprocals
during Kharif, 2010. The resulting 28 crosses along with parents and standard checks Sugar 75 and Madhuri were evaluated in
Randomized Block Design replicated thrice, during Rabi, 2010-11 at Agricultural Research Institute, Rajendranagar, Hyderabad.
The combining ability analysis revealed importance of both additive and non-additive gene actions in governing this particular
trait. The parental lines 6072-3 and 6069 were good general combiners for sugar content and the hybrid combinations 6072-3 x
6100-2, 6104 x 6082 and 6127 x 6100 were considered as good specific combiners for sugar content. The hybrid combinations
6072-3 x 6069, 6072-3 x 6100-2 and 6069 x 6122-1 performed well over standard checks Madhuri and Sugar 75 for sugar content
