| 摘 要： | 以甘肃省600份糜子地方资源为试材，对其株高、千粒重和生育期等11个农艺性状进行主成分分析。结果表明：主要农艺性状可归纳为生育期、株高、米色、主穗长、单株粒重、花序色和抗落粒性7个主成分，累计贡献率为84．97％。该结果可为糜子育种合理选配亲本提供参考依据。

| Abstract: | The principal components analysis on eleven agronomic traits of 600 local broomcorn millet germplasm resources in Gansu Province was carried out.The results showed that the main agronomic traits could be concluded to seven principal components including growth period,plant height,grain color,main panicle length,grain weight per plant,inflorescence color and anti-shattering,and the cumulative proportion achieved 84.97%.The results could provide reference for the reasonable parent selection for broomcorn millet breeding. |
