CHA杂种小麦生长发育及产量优势特性形成的研究

Stydies on the Growth and Development of CHA Hybrid Wheat and Their Heterosis Characteristics During Yield Formation

以 ＣＨＡ杂种及其亲本为材料，探讨了 ＣＨＡ杂种小麦产量优势形成过程的生长发育特点以及不同组合优势性状及其大小，从不同角度阐述了 ＣＨＡ杂种小麦产量优势形成的原因。

The results showed that CHA hybrid wheats heterosis are much different in yield, yield components, agronomical characteristics and physiology traits. The reasons of yield heterosis formation was discussed from different points of view.
