Analysis of Genetic Diversity of Agronomic Traits of Local Broomcorn Millet Germplasm Resources in Gansu Province

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.
