Roles of the canopy wilting trait in yield protection under drought. The two sets of RILs were planted in the field under irrigated and rain-fed conditions at Salina (left) and Delta Center (right). Data shown are means ±SDs of yield plots of 23 RILs for either slow wilting or fast wilting types. Student’s t-test was performed to compare means of traits between the two sets of RILs. The percentages on the columns show the yield advantage of the corresponding wilting types over the others.
