小麦雄性不育杂种优势利用的研究是探讨小麦高产的又一新途径。选育恢复力高,农艺性状优良的恢复系是配制强优势杂种组合的关键。丰富的恢复源又是选育优良恢复系的基础。因此,我们把发现恢复源列为小麦杂种优势利用研究内容的一个方面。1971年,我们利用国内外搜集的大量小麦品种资源,采用测交筛选法,鉴定出 L344/5等几个普通小麦品种对 T 型不育系具有不同程度的恢复力。1972年分株成对测交鉴定出 Wheat heterosis utilization of male sterility is to explore another high-yield wheat pathway. The restorer lines with high resilience and good agronomic traits are the key to formulating strong heterosis hybrid combinations. The rich source of restoration is also the basis for the cultivation of good restoration lines. Therefore, we have identified the discovery recovery source as one aspect of the research on the utilization of wheat heterosis. In 1971, we used a large number of wheat germplasm resources collected at home and abroad to identify several common wheat cultivars such as L344 / 5 with different degrees of resilience to T-type CMS lines. In 1972, the strains were identified in pairs
