Stomatal conductance predicts yields in irrigated Pima cotton and bread wheat grown at high temperatures

Recent studies of historical series from Pima cotton and bread wheat bred for higher yields at supraoptimal temperatures under ample water supply have shown that incremental increases in stomatal conductance have accompanied lint and grain yield increases in successive commercial releases. Pima cotton studies showed that the differences in stomatal conductance are under genetic control. F4 progeny of F2 plants selected solely for high stomatal...
