Abstract:
Six diverse brinjal lines were crossed in a full diallel fashion (Including reciprocals) to study the combining ability of important horticultural traits. Significant differences were observed among the genotypes for most of the traits. The parent Sevanthampatti local and Seetipulam local were identified as good general combiners for earliness (Days to first flowering, and harvesting) individual fruit weight and ascorbic acid content. Whereas, Karungal local was identified as good combiner for number of branches per plant, fruit length, number of fruits per plant, total sugars and yield per plant. The highest specific combining ability effects in desirable direction were observed in a cross Sevanthampatti local x Seetipulam local for plant height, days to first flowering and fruit length. Manaparai local x Karungal local showed positive sca for 1000 seed weight, number of fruits per plant, yield per plant while Spiny local x Marthandam local for days to first harvest, carbohydrate content and protein content.
