试图利用杂交小麦提高单位面积产量,是近十多年来小麦育种的新课题。实践证明,若要大面积推广杂交小麦,如利用现有的Timopheeri雄性不育系(简称“T型”不育系),就必须突破三个难关:一是提高不育系的农艺性状;二是提高育性恢复度;三是测交强优势的杂交组合。同时,必须开展新不育 Attempting to increase yield per unit area of ​​hybrid wheat is a new subject of wheat breeding in the past ten years. Practice has proved that to popularize hybrid wheat in large scale, if we use the existing Timopheeri male sterile line (referred to as “T” sterile line), we must break through three difficulties: one is to improve the agronomic traits of CMS; Is to improve the degree of fertility restoration; third is to test the hybrid cross strong combination. At the same time, new sterility must be carried out
