Zhongyuan 18 wheat is a wheat variety submitted by Henan Jinxiu Agricultural Technology Co., Ltd., and it is a relatively high-quality variety. Let's take a look at the introduction to the Zhongyuan 18 wheat variety below.
1. Characteristics and traits
Weak springness, whole growth period 217 days, maturity period comparable to the control variety Yanzhan 4110. Seedlings semi-erect, leaves wide, vigorous growth, leaf color dark green, winter cold resistance average. Tillering ability medium, spike-forming rate relatively high. In spring, jointing starts early, polar differentiation is fast, tolerance to late spring cold is average. Root activity strong, tolerant to late-stage high temperatures, grain filling fast, maturity appearance relatively good. Plant type slightly compact, plant height 78.8 cm, stem elasticity medium, lodging resistance relatively weak. Flag leaf wide and long, drooping. Spike spindle-shaped, spike layer thick, long awns, white glumes, white grains, grains semi-hard, plumpness medium. Spike number per mu 410,000 spikes, grains per spike 27.5, 1000-grain weight 52 g. Disease resistance identification: highly resistant to stripe rust, moderately susceptible to leaf rust, highly susceptible to powdery mildew, fusarium head blight, and sheath blight. Quality testing: grain test weight 788 g/L, protein content 14.55%, wet gluten content 30.6%, sedimentation value 19.9 mL, water absorption 53.7%, stabilization time 1.2 minutes, maximum stretching resistance 127 E.U., extensibility 133 mm, stretching area 20 sq cm.
2. Yield performance
In the 2012-2013 annual regional trial of spring water group varieties in the southern part of the Huang-Huai winter wheat region, the average yield per mu was 472.8 kg, an increase of 6.0% over the control variety Yanzhan 4110; in the 2013-2014 annual continued trial, the average yield per mu was 561.3 kg, an increase of 6.9% over Yanzhan 4110. In the 2014-2015 annual production trial, the average yield per mu was 525.9 kg, an increase of 7.3% over Yanzhan 4110.
This kind of wheat is suitable for planting in medium and late stubble in Henan, Anhui, Jiangsu and other regions, and is one of the relatively high-quality wheat varieties.
