为了促使小麦象高粱、玉米那样,利用杂种优势,获得大幅度增产,我们从一九七二年开始,连续进行了小麦雄性不育的利用研究,内容有 T 型不育材料及恢复系的转育;G 型不育材料的利用价值和三系配套;杂种小麦的田间制种繁殖技术。下面就 G 型不育材料的遗传机制和利用价值谈点看法。(一)G 型不育材料的来源:一九七二年,我们在小黑麦三号的实验田里发现一株倾小麦类型的半育类型,特点是仅有的几个正常花集中在穗子基部几个枝梗上,穗子中上部小花全部不育,当时采用隔离方法栽培管理,获得了几粒正常花的种子,暂时取名为 G 型。一九七三年,对仅存的四株 F_1代
In order to promote the utilization of heterosis by wheat as sorghum and corn, a substantial increase in yield has been achieved. Since 1972, we have conducted continuous research on the utilization of wheat male sterility, including the transformation of T-type sterile materials and restorer lines Education; G-type sterile material utilization value and three-line matching; hybrid wheat field seed breeding techniques. The following G type sterile material genetic mechanism and the value of talking about point of view. (I) Source of Type G Sterile Materials: In 1972, we found a semi-sterile type of tillering wheat in the experimental field of Triticale III, characterized by only a few normal flowers concentrated in Spike few branches on the base, the upper part of the spikelets are sterile, then the isolation method of cultivation and management, access to a few grains of normal flowers, temporarily named G-type. In 1973, there were only four F_1 generations surviving
