文摘

Recent soybean cultivars out-yield landraces in a water-limited field environment. Two cultivars with high yield when water stressed conserve water prior to flowering. High-yielding cultivars conserve water with low leaf area and reduced transpiration. Water-conserving cultivars have lower root length densities and thinner roots.
