The main objective of the project is to improve the most widely grown and promising groundnut cultivars (that contain low oil content, are drought tolerant and have high haulm yield) for resistance to foliar diseases (rust and late leaf spot) and enhanced oil quality (high O/L ratio) through marker-assisted gene/QTL pyramiding. Parallel marker-assisted backcrossing (MABC) programs will be conducted to transfer QTLs for rust and late leaf spot resistance and high O/L ratio into released varieties and elite breeding lines. The near-isogenic lines carrying different QTLs will be crossed to combine the introgressed traits into each cultivar. The final products will be improved cultivars containing QTLs for resistance to rust and late leaf spot diseases and for high OIL ratio.
