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.
