Abstract: To screen the suitable cross parents of wheat, 51 accessions American wheat germplasms introduced in 2015 were used as experimental materials. The frequency distribution and genetic diversity of four qualitative traits were studied. The correlation and the genetic diversity of nine main agronomic traits were analyzed. Taking the main agronomic characters as the indexes, 51 accessions American wheat germplasms were analyzed by the clustering analysis. The main plant type of the tested wheat germplasms is erect, the main panicle type is spinner bait, long awn is the main awn type, the main flag leaf type is downward. The yield is significantly and positively correlated with the number of productive ear (0.472**), and positively correlated with the 1000-grain weight (0.340*). There are great differences among the nine agronomic characters, the CV of each trait is more than 5% except bulk density (1.71%). The variation coefficient of sterile spikelet (55.21%) is the highest, and these germplasms have abundant genetic diversity. 51 accessions American wheat germplasms are classified into 4 groups by Ward method. Group I has the maximum 1000-grain weight (40.31 g), number of productive ear (656.74×104/hm2) and yield (8718.63 kg/hm2), which could be used as excellent cross parents, the other germplasm could be used as intermediate material for improving some traits according to the characteristics of taxa.
