| 摘 要： | 1983～1989年用半姊妹法完成了3轮轮回选择,结果表明C1、C2、C3较C0分别增产7.8%、11.3%和22.7%,株高分别降低了18.7cm、7.1cm和6.3cm,穗位高和生育期无显著变化.伴随产量的提高,其相关性状:果穗长、千粒重和行粒数显著增加,穗行数、穗粗、出籽率基本稳定.统计分析表明,产量与穗长、千粒重变化呈显著正相关.

| Abstract: | Three cycles of selection was carried out with half-sib method.The results showed that C1, C2, C3 increased by 7.8%,11.2%,22.7% for grain yield respectively, as compared with that of C0.While the plant height decreased by 18.7cm,7.1 cm,6.3cm respectively, as against that of C0.Ear Ienght,TKW and kernel number/row increased significantly with the yield increasing, but no change occured in no.of row/ear,ear diameter and kernel percentage. |
