Through analysis and comprehensive screening of agronomic and yield traits of 10 Xinjiang prosomillet(Panicum miliaceum L.)germplasm,significant differences and correlations were generally found among the tested materials.Under the same planting and cultivation conditions,XY and HBH are classified as super early maturing materials based on a growth period variation of 55~83 days.HP,H33,HK,and HC are classified as early maturing materials,TL,BRG are classified as late maturing materials,TLD and WS are classified as late maturing materials.In terms of grain yield,the variation range is 1 905.95~4 237.12 kg/hm2,with H33 having the highest yield.The degree of variation of agronomic and yield traits among different qualities is expressed through coefficient of variation and diversity index.The range of variation between different qualities is between 7.92%and 43.71%,and the range of genetic diversity index variation is between 2.22 and 2.57,with a mean of 2.33.System clustering analysis divides 10 materials into three categories:high-yield materials for grains,high-yield materials for feed,and early maturing materials.The membership function analysis sorts the comprehensive score D values of each material and screens the selected materials.
