由湖南省科委和湖南省教委下达,湖南杂交小麦研究中心何觉民教授、张海清副教授等承担的“通北野燕麦与小麦族间杂交的研究”课题,最近又获得突破性进展。1.首次以普通小麦作母本与通北野燕麦杂交获得成功。其杂种后代群体分离大,形态、抗性、生育期等均与母本有很大差异,目前已获得一大批高产、抗病、优质的品系。经鉴定,杂种F_1花粉母细胞减数分裂异常,用G-带法检验发现杂种根尖染色体显示出通北野燕麦的特征带型。2.对贵州农学院张庆勤教授创造的节节麦×通北野燕麦杂种双二倍体(简称节燕麦,下 The project entitled “Research on Hybridization between Oat and Wheat in Tongbei Wild” undertaken by Hunan Science and Technology Commission and Hunan Provincial Education Commission, and by Professor He Juemin and Zhang Haiqing, Hunan Hybrid Wheat Research Center, recently achieved a breakthrough. 1. For the first time, common wheat as a female parent and Tongbei oats hybridization success. The offspring of their offspring segregated large, morphological, resistance, growth period are very different from the female parent, has received a large number of high yield, disease resistance, high quality strains. It was identified that hybrid F_1 pollen mother cell meiosis abnormalities, G-banding test showed that the hybrid apical chromosome shows the characteristic band type of wild north oats. 2. Guizhou College of Agriculture Professor Zhang Qingqin created section of wheat × pass wild oat hybrid double diploid (section oats, under
