Inheritance of High Oleic Acid Content in New Sources of Groundnut (Arachis hypogaea L.)
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.
