| 摘 要： | 在当前小麦杂种优势利用研究未取得重大突破的情况下,无法直接利用小麦杂交一代用于大田生产,但如果选择适合的杂交二代作种子,可有效规避小麦杂交一代直接利用的各种制约因素,我们对现有的小麦杂交二代进行选择,并进行品种比较试验,筛选出了有明显产量优势可利用的杂交二代组合,试图为杂交小麦研究找一个新方向.

| Abstract: | Under the current circumstances that there are no momentous innovation of the studying of hybrid wheat,the first-generation of wheat hybrid could not be used to field production directly,but if we choice suitable seeds of second-generation of wheat hybrid as seed,we can effectively circumvent the various constraints which inhibit the direct use of the wheat hybrid first-generation.Through certain choices in the existing wheat hybrid second-generation and variety comparison tests,sift and find some second-ge... |
