新育成的小麦品种冬早Ⅰ号及Ⅱ号，经连续３ 年试验证实，其产量和京郊农村主栽品种京４１１ 处于同一水平，综合性状良好，而早熟性是其突出的优势，抽穗期平均比对照京４１１ 提早６ 天，成熟期早４ ～５ 天。经研究，初步判断早熟品种属冬性对光温反应较不敏感类型，在阶段发育上具有一些特点，其越冬抗寒力强，较好地适应我国北部晚熟冬麦区的生态环境条件。还就成熟期的变异、阶段发育和分蘖成穗的特征作了描述，为新品种的农业生产应用提供依据
The newly bred wheat variety Dongzao I and II, confirmed by continuous three years of experiment, showed that the yield was in the same level as that of Jing 411 in the rural suburbs of Beijing, the comprehensive characters were good, but the prematureness was its prominent advantage. The heading date On average, Jing 411 is 6 days earlier than that of Jing 411, and maturity is 4 ~ 5 days earlier. According to the research, the early maturing varieties are preliminarily judged to be less sensitive to light and temperature in winter and have some characteristics in the stage of development. They are strong in winter and cold-hard and can well adapt to the ecological environment conditions of the late maturing winter wheat in northern China. Also described the characteristics of variation, stage development and tillering to mature spike in mature stage, which provided the basis for the application of new varieties of agricultural production
