Plum [Prunus salicina Lindl. (syn. Prunus triflora Roxb. or Prunus thibetica Franch.)], commonly known as chinese plum or japanese plum, is a diploid (2n = 2x = 16) fruit tree native to China. It is one of the most important stone fruit crops in the world (Bhutani and Joshi, 1995). The total world production of plums was 10,776,232 t in 2009, of which 5,372,899 were produced in China (Potter, 2012). China also has rich plum germplasm resources, which are attributed to a long history of natural and artificial selections for fruit yield and quality as well as for adaptation to a wide range of ecological conditions (Liu et al., 2007). ‘Naili’ and ‘Furongli’ are two groups of famous landraces in Fujian Province (Zhang and Zhou, 1998), located on the southeast coast of China. ‘Naili’ was described in ancient Chinese books as ‘Ba Min Tong Zhi’ in Song Dynasty in 1214 and ‘Pu Yang Zhi’ in Ming Dynasty in 1485. ‘Naili’ includes ‘Hua Nai’ and ‘Qing Nai’ (Qiu and Lu, 1980). The fruit of ‘Qing Nai’ is round with a green yellowish color (142D, Royal Horticultural Society, 2001). This variety has been widely produced as fresh fruit due to its delicious taste. This report describes a new selection of plum derived from ‘Qing Nai’.
