通过对12个大麦杂种组合F19个性状中亲优势的研究分析，结果表明：杂种F1在株高、穗长、千粒重、穗下节长均表现为一致的正向中亲优势；着粒密度表现出一致的中亲负向优势；其余各研究性状的中亲优势在不同的组合表现不同；明确了应选用平均株高适中的两亲本配制杂种；并可通过F1穗下节长来选择单株粒重较高的组合。
The results showed that hybrid F1 showed consistent positive parental progenies in plant height, spike length, 1000-grain weight and spike length. The grain density The same middle parents had the negative advantage; the other progenies of each research trait showed different performance in different combinations; it was clear that the average hybrid height should be used to prepare hybrids; A combination of higher grain weight.
