Significant at 5% and 1% probability levels, respectively. DF: days to flowering; DM: days to maturity; BP: number of branches/plant; PP: number of pod/plant; STMLC: stomatal conductance; LWP: leaf water potential; HSW: 100-seed weight; BG: biomass aboveground; GP: number of grain/pod; YP: yield/plant; HI harvest index.
