天津市农科院作物所张湘泉等首次利用阶梯式轮回选择法育成抗寒冬小麦新品种TBT6号,并于1993年5月在天津通过了成果鉴定。 TBT6号以核不育小麦的不育株为基础亲本,先后向不育林群体内加入34个不同类型的轮选亲本聚合杂交,然后对可育株进行系统选择而成。丰富的遗传基础使微效多基因得以聚合,将小麦丰产、抗病、抗寒、耐 Zhang Xiangquan, a crop scientist at Tianjin Academy of Agricultural Sciences, developed the first cold-tolerant winter wheat cultivar TBT6 using the stepwise recurrent selection method and passed the appraisal in Tianjin in May 1993. TBT6 was based on the male sterility strain of sterile wheat. The hybrids of 34 different types of selected rotation parents were successively fed into the sterile plantation, and then the fertile plants were systematically selected. Rich genetic basis to micro-multi-gene to polymerization, the wheat yield, disease resistance, cold, resistance
