- Abstract
Line x tester analysis was carried out involving twelve lines and three testers for assessing the combining ability for yield and its component characters in pumpkin (Cucurbita moschata Duch.ex Poir). The combining ability analysis revealed that highly significant differences among the treatments for all the parameters were exhibited by the genotypes. The variance due to sca was higher than the gca for all the characters indicating the predominance of non-additive gene effects. Out of 15 parents used in the study, the lines Vadhalagundu local followed by Kasi Harit were the best combiners for days to first female flower appearance, first female flowering node number, sex ratio, days to first harvest, fruit number per vine and quality characters viz., carbohydrate content, total carotenoids content and fruit yield per vine as they expressed significant gca effect. Among the testers, CO 2 had significant gca effect for days to first female flower appearance, first female flowering node number, sex ratio, fruit number per vine, total carotenoids content and yield per vine and the tester Arka suryamukhi also expressed significant preferable gca value for days to first harvest, carbohydrate content and total carotenoids content. The cross Kasi Harit x Avinashi local were identified as good specific combiner for days to first female flower appearance, first female flowering node number, sex ratio, fruit number per vine, flesh thickness, total carotenoids content, and fruit yield per vine followed by Vadhalagundu local x CO 2 for first female flowering node number, sex ratio, carbohydrate content, total carotenoids content fruit number per vine and fruit yield per vine.
