Abstract:
Combining ability analysis was computed for thirty four traits in thirty six hybrid combinations (including parents) in snap melon. GCA and SCA variances were significant for all the characters. The parent P₆ was found to be the best combiner for number of fruits per plant, fruit yield per plant, flavonoid and calcium content. The parent P₂ ranked 1^st for fruit length, fruit girth, fruit weight, total carotene, fibre and alkaloid content. The parent P₅ recorded positive and significant general combining ability effects for days to 1^st female flower appearance. The hybrid P₂xP₄ exhibited positive and significant sca effects for the trait fruit length, fruit girth, fruit weight and fruit yield per plant.
