The experiment was undertaken to study the combining ability for yield and its attributing traits in groundnut. The experimental material consisted of four lines and five testers mated in L X T mating design. Analysis of variance for combining ability for the traits viz., plant height, number of pods plant-1, dry pod yield plant-1, dry haulm yield plant-1, hundred kernel weight, shelling percentage, sound mature kernel, days to maturity, oil content were highly significant for female, male and female vs male parents. Protein content was highly significant for female and female vs male and positive but non-significant for male. Among the male parent, TAG 24 recorded higher mean performance for most of the characters and identified as good combiner for some of traits while as among the female line RHRG 6083 recorded higher mean performance and identified as good combiner with significant gca effects for most of the characters, could be utilized for further hybridization programme. Higher magnitude of sca and low value of gca effects indicated influence of non-additive gene action. On the basis of per se performance and combining ability the hybrids viz., RHRG 6083 X TAG 24, Konkan Gaurav X KDG 209 and RHRG 6083 X RTNG 29 were found to be the most promising combinations in most of the yield contributing traits and may be exploited in further plant breeding programme or identification of transgressive sergeants from the further generations.
