Evaluation of Recombinant Inbreed Lines of TG 49 × GPBD 4 and its reciprocal cross under organic cultivation in groundnut (Arachis hypogaea L.)

Groundnut is an important oil seed, food and forage legume. The crop is severely affectedby foliar disease and yield potential under disease pressure has been rarely investigated. Groundnut beingan edible oil seed crop has large scope if cultivated organically. Hence evaluation of RILs of TG 49 × GPBD 4 (187 RILs) and its reciprocal cross (GPBD 4 × TG 49) was studied. The Genetic variability in these mapping populations was assessed by growing them under organic condition at MARS, Dharwad. High PCV, moderate GCV, moderate heritability and low genetic advance was recorded for pod yield, Moderate PCV and GCV recorded for 100-seed weight, GCV and PCV for rust and LLS revealed significant variation indicating moderate to high level of variability for TG49 × GPBD 4 population in which 1–27 Transgressive segregant observed for combination of traits. GCV and PCV for both the diseases revealed significant variation. Low PCV and GCV, high heritability and low genetic advance were recorded for protein and oil in both populations.
