It belongs to Rutaceae family and Hong Kong kumquat （Fortunella hindsii Swingle）. Since 2013, through three years investigation on its botanical and biological characteristics and fruit quality, we found that its genetic traits were stable. SSR molecular markers were performed on the plant materials of ＇ Gui Wild Shanjingan＇ and 6 other citrus varieties to analyze their phylogenetic relationship. The results showed that ＇Gui Wild Shanjingan＇ was a new citrus cul- tivar with specific bands which was different with the other tested cultivars, and it was reviewed and approved by the Guangxi Committee of Corp Variety Registration in June 2015.
