K型杂交小麦不育系繁殖技术研究

Study on Seed Reproduction Technique of Wheat Sterile Line of K Type Hybrid

对杂交小麦不育系繁殖中的播期、行比、播量等研究表明 :父母本的差播期为二叶期 ,行比为 1∶ 3(播幅 1 .5m) ;母本播量为 1 2 0 kg/ hm2 的大田常规播种量 ,可以提高 K型 (粘果山羊草细胞质 )小麦雄性不育系

The seed reproduction techniques of wheat male sterile line such as different planting date, the ratio of male to female line and different female sowing period were studied in the paper. The result showed that the difference in planting period of the parent occurred in the second leaf, the ratio of male to female parent was 1∶3 (1.5 meter drill strip width) and the female parent utilize 120 kg/hm 2 could increase seed reproduction and economic effect of the wheat male sterile line K7664A(with Aegilops kiotschyi cytoplasm) in Guanzhong area in Shaanxi Province.
