The 11 quantitative traits were classified and diversity of 54 morphological characteristics were analyzed with 22 gerbera varieties. The results showed that 11 quantitative traits can be classified to five or seven continuous grades, 3-7 or 2-8 incomplete scale was set up. There were 162 alleles for 54 morphological characteristics variations in 22 gerbera varieties, the average was 3.0. The average effective alleles was 2.0209 (1.0000 ~- 3.9672). The Shannon's diversity index averaged from all morphological characteristics was 0.7578 with a range of 0.0000 ~ -1.4650. Similarity coefficient of 22 varieties was from 0.67 to 0.86. The 22 gerbera varieties can be divided into three groups according the threshold with similarity of 0.70. Varieties of single flower or bicolored varieties with 2 colors on the outer side of outer ray floret can effectively distinguish from other varieties.
