| The field survey and study were made on the diversity for of 22 main characters of 474 local foxtail millet germplasm resources in different regions of Gansu Province.The results show that there are large range of variability and rich genetic resources of foxtail millet germplasm in Gansu.And the genetic diversity of germplasm resources in different regions is significantly different.It is rich in Lanzhou,Baiyin,Dingxi,Linxia,Qingyang and Wuwei.whose diversity indexes are during ranged from 1.5312～1.3424. But the diversity index is relatively lower in Jinchang and Longnan,whose diversity indexes are ranged from 0.8018～0.4970.The difference of diversity of various regions is significant and their diversity indexes are ranged from 0.0000～2.1383.Of 22 characters surveyed,6 characters,for examples,grain protein content,length of main stem,1000-grain weight,main panicle length,grain fat content,grain lysine content,etc.,show higher diversity indexes than other characters like hulless grain color,seeding leaf color,spike shape,etc. |
