我所从1960年开始,连续进行16年的小麦夏播试验,共播种国内外各种类型的小麦品种(系)830多个(次);杂交材料一代874个组合国;二代至九代的株系5,600多个。除选育新品种外,并对小麦夏播的遗传、变异、生理、生态和栽培等方面进行了一些研究。一、小麦夏播的表现(一)小麦夏播在抽穗结实方面明显地存在三种情况:冬性品种不能抽穗结实;春性品种都能抽穗结实;界于二者之间的弱冬性或偏春性品种能部分或大部分抽穗结实。这主要是由于夏季自然环境条件和小麦的阶段发育特性所决定的。特别是后者在抽穗期和
Since 1960, we have been conducting summer wheat sowing trials for 16 years in succession. We have planted more than 830 varieties of wheat varieties of all kinds at home and abroad; 874 hybrids of the first generation of hybrid materials; second- to ninth- More than 5,600 lines. In addition to breeding new varieties, and some researches on the genetic, variation, physiology, ecology and cultivation of summer sowing wheat. First, the performance of summer sowing of wheat (A) Summer wheat sowing evident in the heading of three obvious cases: winter varieties can not be heading; spring varieties can erect; between the weak winter or Springy varieties can be partial or most of the heading edible. This is mainly due to the natural environmental conditions in summer and wheat stage development characteristics of the decision. Especially the latter at heading date and
