Abstract: The morphological sturcture and flowering characteristics of Chorisia speciosa were investigated through a grafting test. The results indicated that there were remarkable differences among stands or clones in flowering period, type, petal size and color. In general, the flowering period could reach 190 d, ranged from August to March of the next year with a full blooming time during midmonth of October spanning to November early. The flower types were straight (82.47% of the clones) and anti-roll. The color of petal base appeared to be white, white-yellow (95.44% of the clones), weak yellow or yellow; while the tip of petal could be observed with the color of white, weak red, red (59.09% of the clones), dark red, or violet. The average length and width of flowers were 10.51 cm and 11.91 cm respectively. According to the length-width ratio, the petal showed as strip, cochlear (46.75% of the clones) or big cochlear type. Cluster analysis revealed that all the clones could be classified into 7 groups (e.g. straight stem early large flower with wide petal, straight stem late larger flower, and areca late smaller flower). Of which, the type with straight stem early large flower with wide petal was more attractive and should be concentrated in the breeding program.
