Abstract:

Line x Tester analysis was carried out for thirteen diversified parents at the department of Horticulture, Agricultural College and Research Institute, Madurai, Tamil Nadu, to study the combining ability for yield and yield contributing characters in snake gourd. The analysis for combining ability revealed significant mean sum of squares of both general combining ability (GCA) and specific combining ability (SCA) for all the characters which indicate that the presence of both additive and non-additive gene actions. The line IC 284753 (L5) and IC333314 (L2) were found to be best general combiners, for majority of the yield and yield contributing characters. Among the testers Kumbakonam Local (T3), Kulithalai Local (T1) and Jeyamkondam Local (T2) were found to be good general combiner for yield contributing characters viz., vine length, fruit length, fruit girth, average fruit weight, number of fruits per vine, number of seeds per fruit and yield per vine. Among the hybrids L2xT3, L7xT2, L2xT4, L5xT1 and L8xT4 were found to be the good specific combiners (gca) for most of the yield and yield contributing characters. These cross combinations can be utilized for further breeding programme for crop improvement in snake gourd.
