| 摘 要： | 利用新选育出的质核互作型雄性不育系和筛选出的恢复系配制杂种．研究了各组合的杂种F1的中亲优势、高亲优势和对照优势。结果表明．杂种F1农艺性状和产量构成性状均存在一定的杂种优势．产量构成性状的杂种优势在不同类型组合间存在较大的差异．杂优利用在多棱大麦组合和多棱×二棱大麦组合中的应用前景更为广阔．

| Abstract: | Hybridizations were made with new male -sterile lines and screend restorers. The mid-parent, superhigh - parent and contrast heterosis of hybrids were studied. Results showed that: the heterosis of both agronomic traits and yield components had been showed in hybrid F1. The heterosis of yield components differed largely among different combinations. Crosses of sixrowed bar ley or six - rowed with two - rowed barley had broader prospects. |
