目前,T型小麦三系已经配套,农艺性状水平不断提高。但是,从近年来试配的杂交组合来看,杂种优势不够明显,在生产上难以利用。现在急需选配强优势组合,并对T型小麦的杂种优势进行深入的分析,以便在生产上广泛利用。为了予测杂种优势,国内外学者在许多方面作了大量工作。植物同工酶的发现,为分析鉴定植物的杂交组合提供了一条新途径。最早应用同工酶研究杂种优势的是1960年Schwartz, At present, T-type wheat three lines have been supporting, agronomic traits continue to improve. However, judging from the cross combinations that have been tried in recent years, the heterosis is not obvious enough and is difficult to be utilized in production. There is an urgent need to match the strong combination of advantages, and in-depth analysis of the heterosis T-wheat in order to be widely used in production. In order to predict the heterosis, many scholars at home and abroad have done a lot of work. The discovery of plant isozymes provides a new way of analyzing hybrids that identify plants. The earliest application of isozymes for heterosis was 1960 Schwartz,
