In view of growing importance of oil quality, an understanding of the inheritance of high oleic acid is essential to breed for high oleate groundnuts. Hence an investigation was undertaken to infer genes governing the high oleic acid in newly identified sources of groundnut. Number of crosses studied were one with low  ×  medium  (TAG  24  × TPG  41),  two  with low × high (TAG  24 × ICG  2381 and TAG  24 × 104  P51)  and with one  medium × high  oleic  acid  (TPG  41 × 104  P 56) cross combinations during  post  rainy season of  2010 at Main Agricultural Research Station of University  of  Agricultural  Sciences, Dharwad, India. Individuals in  F2  generation segregated  in the ratio 3:1  in  the  crosses of low × medium and  medium × high crosses and 15:1 in  low × high  cross combinations suggesting duplicative  recessive genes governing  the  high  oleate  trait.
