The faintest color of the bud color is yellow green. In addition, the variation-coefficient of some morphological traits is very low such as the cotyledon length, the cotyledon width, the cotyledon color, the silique length and so on. The Cluster analysis was based on the morphological data. When the genetic distance was 7.61, 21 accessions were clustered into 4 groups. The accessions of the group 1 had white petal, mezzo flower stalk and the earlier pick period, which is divided into two subgroup when the genetic distance was 5. 98. And the model was Ba39 and Ba35. The accessions in the group 2 had the very slender flower stalk and the middle pick period, that model was Ba27. The accessions of the group 3 had yellow petal, the thin flower stalk and the later pick period, that model was Ba43. The main characters of the group 4 were that it had the latest pick period and many leaves.
