The present study on combining ability for yield and its components was carried out in a set of 27 F1 hybrids of cucumber obtained from a line × tester method involving 12 diverse parents at Zonal Agriculture and Horticulture Research Station (ZAHRS), Navule, Shivamogga, Karnataka during rabi 2016-17. The ratio of the genetic variance was less than unity, which indicated the predominance of the non-additive gene action. The analysis revealed that none of the parents were found good general combiners for all the traits consistently, however parents US-640, Himangi and Haveri Local were good combiner for fruit yield and its contributing traits. The hybrids DWD × Haveri Local, US-640 × Haveri Local and Sabra × Bagalkot Local exhibited the significant positive specific combining ability (sca) effect for yield attributing traits. These crosses involved poor × average and poor × good combiner parents. Further, improvement in fruit yield could be possible through the hybridization and selection in transgressive segregants.

Key words: Cucumber, Combining ability, Hybrids, Non-additive gene action
