Introduction to the Characteristics and Traits of the Wanmai 52 Wheat Variety

Characteristics and traits: Semi-winter type, mid-late maturing, maturity 1-2 days later than the controls Yumai 49 and Xinmai 18. Seedlings semi-prostrate, leaves slender and upright, medium tillering ability, relatively high percentage of productive tillers. Plant height about 85 cm, plant type relatively compact, flag leaf broad and short, upright. Spike layer thick, spike spindle-shaped, numerous and uniform spikes, spike head on the small side, long awns, white glumes, white kernels, kernels semi-hard, good luster, fairly good plumpness, medium black point rate, fairly good market quality. Average spikes per mu 400,000 spikes, grains per spike 36.3, 1000-grain weight 40.9 g. Vigorous growth at the seedling stage, fairly good cold resistance. Jointing relatively early, rapid polarization, heading relatively late. Fairly sensitive to low temperatures in spring. Possesses a certain degree of drought tolerance, good maturity appearance. Stem elasticity average, moderate lodging resistance. Disease resistance evaluation: moderately resistant to slow leaf rust, moderately susceptible to stem rust, powdery mildew, and stripe rust, highly susceptible to fusarium head blight and sheath blight. Field performance in regional trials: moderately susceptible to leaf rust. Mixed samples tested in 2006 and 2007 respectively: test weight 796 g/L and 798 g/L, protein (dry basis) content 13.41% and 14.85%, wet gluten content 31.2% and 32.3%, sedimentation value 29.3 mL and 26.2 mL, water absorption 66.7% and 51.2%, stability time 2.6 minutes and 2 minutes, maximum resistance to extension 120 E.U and 193 E.U, extensibility 14.5 cm and 15.4 cm, extension area 26 sq cm and 43 sq cm.

Yield performance: In the 2005-2006 season, participated in the regional trial of the winter water group in the southern Huang-Huai winter wheat region, average yield per mu 559.9 kg, 6.29% higher than control 1 Xinmai 18 and 6.82% higher than control 2 Yumai 49; in the 2006-2007 season continued trial, average yield per mu 554.7 kg, 6.29% higher than control Xinmai 18. In the 2006-2007 season production trial, average yield per mu 526.1 kg, 6.3% higher than control Xinmai 18

Key cultivation techniques: Suitable sowing period is early to mid-October, suitable basic seedlings per mu 100,000-140,000 seedlings. Pay attention to lodging prevention in high-water and high-fertility fields. Pay attention to the control of fusarium head blight and sheath blight.
