Abstract:
Five lines were crossed with four testers in a line x tester mating fashion to study combining ability for fifteen yield attributing and three quality characters in groundnut. ANOVA revealed the existence of substantial variance among the breeding material for all the eighteen traits studied. The estimates of mean sum of squares due to lines, testers, crosses and their interaction showed significant variation for all the traits. The extent of sca was more than gca variance indicated the influence of non-additive gene action in the inheritance of characters. Based on the mean performance and gca effects, the lines Kadiri-6 and Narayani, and the testers ICGV-171377 and ICGV-06188 were resulted as superior parents for yield, yield attributing and quality traits. On the basis of mean performance and sca effects of twenty crosses, four cross combinations viz., Dheeraj x ICGV 171377 was ideal cross for yield. Whereas, Narayani x ICGV-06188, Kadiri-6 x ICGV-95165 and Kadiri-6 x ICGV-171377 were considered as best crosses in improving yield along with quality characters and could be utilized in further breeding programmes to isolate desirable segregants with low oil content, high protein content and high sucrose content.
