A study in Hebei province looked at 85 winter wheat varieties to find ones that yield well and resist drought. They grew the wheat under drought conditions and irrigated it twice. They found that traits like spike number and grain yield were closely related. To improve yield and drought resistance, breeders should focus on traits like spike number, grains per spike, and flag leaf length. They also identified traits like grain specific gravity and spikelets per spike that can help identify drought-resistant wheat varieties in Hebei. Overall, wheat varieties in Hebei have high yield potential but need better drought resistance.
