Combining ability studies for yield contributing traits in cucumber (cucumis sativus L.)

The present study on combining ability for yield and its contributing traits in cucumber (Cucumis sativus L.) was undertaken during 2019-20 at Department of Genetics and Plant Breeding, College of Horticulture, Mudigere and Agricultural and Horticultural Research Station, Bavikere. Twenty-eight hybrids derived by crossing of eight parents using half diallel mating design were evaluated along with parents and standard check in a randomized complete block design. The variances due to genotypes varied significantly for all the traits studied. The Parents malini and nungems were identified as good general combiners for overall characters studied. Similarly, crosses malini x sabra and malini x nungems were identified as good specific combiners. GCA to SCA ratio was found greater than unity for all the traits indicating the pre dominance of additive gene action which can improve through recurrent selection on heterosis breeding.
