利用提莫菲维核质互作体系配制杂交小麦是目前小麦杂种优势利用研究中进展较快的一个部分。但是由于在杂种育性恢复方面还存在一些问题,杂交小麦仍未能在生产上发挥应有的作用。我们自1973年起作了一系列杂交试验对杂交小麦的产量和杂种优势进行比较分析,目的是探索目前提型杂交小麦优势不够大的原因并提出讨论的意见。
The use of Timofeev nuclear-protein interaction system for the preparation of hybrid wheat is the utilization of wheat heterosis is progressing part of the rapid progress. However, due to some problems in the recovery of hybrid fertility, hybrid wheat has not yet been able to play its due role in production. We have conducted a series of hybridization experiments since 1973 to compare and analyze the yield and heterosis of hybrid wheat with the purpose of exploring the reasons why the advantages of the present hybrid wheat are not large enough and to put forward the opinions for discussion.
