Development of groundnut genotypes with higher productivity coupled with appropriate quality attributes is essential to boost the use of groundnut for direct consumption and to sustain the groundnut farming. Large-seeded groundnuts command a premium price both in the domestic and international markets. Seven advance breeding lines were evaluated for two seasons along with 3 check varieties possessing large seed size. Analysis of data indicated that the genotypes differed significantly for all the traits except for oil content. Three advance breeding lines, 'PBS 29077', 'PBS 29078' and 'PBS 29080', were found to possess superiority for both pod and kernel yields over the best check for yield 'GG 20'. The genotype 'PBS 29077' exhibited significantly higher seed size (100-kernel weight of 58.2 g) than the best check 'TKG 19A for the trait, while 'PBS 29078', 'PBS 29080' and 'PBS 29071' recorded seed size that was numerically superior to the checks. Highest mean harvest index was observed in 'PBS 29077' (40.9%). Because of the yield potential as well as seed size superiority 'PBS 29077', 'PBS 29078' and 'PBS 29080' would help the groundnut farmers in reaping rich dividends and to abate the competition from other lucrative crops like cotton, which is fast encroaching the traditional groundnut belts in India.
