杂交小麦研究(指以提莫菲维胞质雄性不育为基础材料的小麦杂种优势利用研究,)目前已进入选配强优势组合在生产上试种阶段,国内外不少研究单位都选配了一些杂交组合,经试种表现了一定的增产作用。但存在的共同问题是:杂种优势不强、不稳,增产幅度小,且不能连续表现增产,其原因主要是不能保证杂种每穗结有充足的粒数。因此,如何提高每穗结实粒数已成为杂交小麦 Hybrid Wheat Research (refers to the use of Timofeev cytoplasmic male sterility as the basis for wheat heterosis utilization research) has now entered the selection of strong combination of advantages in the production of the cultivation phase, many domestic and foreign research units are optional Some hybrid combinations, the test showed a certain increase in yield. However, the common problems are: the heterosis is not strong, unstable, increase rate of small, and can not continue to show yield, the main reason is unable to ensure hybrids per ear sufficient grain. Therefore, how to increase the number of grains per panicle has become a hybrid wheat
