According to the flora of China and related literatures, the confused naming of varieties of Chinese quince fruit in China was clarified. It was ascertained that the Chinese quince fruit, the four season-Chinese quince fruit and the multicolor Chinese quince fruit with univalve belong to [WTBX]Chaenomeles speciosa. The great richness, the carbuncle, the beryl and the bright red sun which are pleiopetalous belong to [WTBX] Chaenomeles sinensis. The Chinese flowering quince fruit with slick cuticle and officinal value belong to [WTBX]Chaenomeles sinensis. The fake flowering quince fruit being used as the substitute for the Chinese flowering quince fruit acturally has the formal name of [WTBX]Chaenomeles cathayensis. The floristic family of the plants from different main growing locations in China were testified in this paper. Those varieties growing in Caozhou, Heze city, Shandong province belong to [WTBX]Chaenomeles sinensis,However, those from Yizhou of Yimeng, Shandong province and from Xuancheng city, Anhui province belong to [WTBX] Chaenomeles speciosa. Quince fruite growing in Yunnan includes [WTBX]Chaenomeles speciosa, Chaenomeles sinensis, Chaenomeles cathayensis, Chaenomeles thibetica Yü [WTBX]and Chaenomeles [WTBZ]sp. Commercial values of different varieties of Chinese quince fruit and some famous varieties were also introduced. In addition, some suggestions on how to ameliorate the chaotic naming situation combining the morphological characteristics and molecular markers as well as some basic principles for utilization and breeding of varieties of Chinese quince fruit were put forward here.
