| Innovation Title | Markers deployment in breeding programs in groundnut, sorghum and soybean |
| Innovation description | Marker-assisted backcrossing (MABC) is the most successful approach to introgressing or pyramiding one or more traits using traitlinked markers. We used MABC to improve three popular Indian cultivars (GJG 9, GG 20, and GJGHPS 1) for foliar disease resistance (FDR) and high oleic acid content. To improve Annigeri 1 and JG 74, we introgressed a genomic region conferring resistance against FW race 4 (foc4) through marker-assisted backcrossing using WR 315 as the donor parent. |
