For each parameter, average values of three AtDREB1A transgenic peanut from each plant along with WS were used. Where, WS, water-stressed; WT, wild-type; RW, root-weight; SW, shoot-weight; PW, pod-weight; TB, total biomass; HI, harvest index; RSR, root:shoot ratio; PR, Proline; OP, Osmotic potential; RWC, Relative water content; EC, Electrolytic leakage; CH, Chlorophyll content. Where, * and ** indicates significant and highly significant correlation at *P ≤ 0.05, and **P ≤ 0.01 respectively.
