整个试验数据的分析表明：收获指数可以作为小麦育种早期分离世代对产量性状进行选择的一个标准。
The analysis all of the experiment data indicate that the harvest index can be as a standard of selection of the early separate generations of the wheat breeding.
DON含量的狭义遗传力为74.54%，因此以抗DON积累为指标的赤霉病抗性育种，可以在早期世代进行选择。
The narrow sense heritability of DON content in grains was 74.54%, indicating that it is feasible to select lines with low DON content in earlier generations.
早期世代蛋白质含量的选择强度不宜太大，F2代的选择率以15%为宜，而F3和F4代的选择率以10%为宜。
In the early generations the selection should not be too strict, and 15% selection intensity was suitable in F2 generation, but 10% was suitable in F3 and F4.
