环冬4号由杂交组合83-84-1-1的分离单株系统选育而成。2006—2008年在甘肃省冬小麦区域试验中,折合平均产量3518.7 kg/hm2,较对照品种西峰27号平均增产6.98%;2008—2009年度在甘肃省冬小麦生产试验中,折合平均产量3 600.0 kg/hm2,较对照西峰27号平均增产4.22%。籽粒含粗蛋白147.2 g/kg(干基)、粗淀粉637.7 g/kg(干基)、湿面筋263.8 g/kg(14%水分基)、赖氨酸3.82g/kg(干基)、沉淀值40.5 mL(14%水分基)、容重792.8 g/L、水分11.9%。抗寒抗旱性优良,抗春冻、高抗红黄矮病,抗倒伏、抗青干,抗穗发芽,丰产性好,品质高,适宜在庆阳市北部及同类地区种植。
Huan Dong 4 was isolated from the isolated single-line system of hybrid combination 83-84-1-1. 2006-2008 Gansu winter wheat regional trials, equivalent to an average yield of 3518.7 kg / hm2, compared with the average variety Xifeng 27 yield an average of 6.88%; 2008-2009 winter wheat production in Gansu Province, the average yield of 3 600.0 kg / hm2, compared with the control Xifeng 27 average yield of 4.22%. The kernels contained 147.2 g / kg crude protein, 637.7 g / kg crude starch, 263.8 g / kg wet gluten (14% moisture), 3.82 g / kg lysine Value of 40.5 mL (14% moisture base), bulk density 792.8 g / L, moisture 11.9%. Cold and drought resistance, high resistance to red and yellow dwarf disease, lodging resistance, resistance to green stems, spike resistance, high yield and good quality, high quality, suitable for planting in northern Qingyang City and similar areas.
