Investigation and classification of the five tetraploid Fragaria species native to China
China has more wild strawberry species than any other country in the world. There are five tetraploid species, Fragaria orientalis Lozinsk., F. corymbosa Lozinsk., F. gracilis A. Los., F. moupinensis (Franch.) Card., and F. tibetica Staudt & Dickoré, only or mostly distributed in China. In this paper, 50 wild tetraploid Fragaria samples were collected from northeastern, northwestern and southwestern China and identified to five species. Their taxonomic traits of leaf, stolon, flower, fruit and pubescence were described and compared in detail. The sex of the plants was also observed. Female and male plants were observed in each of the five species. This information will help differentiate these tetraploid strawberries, some of which are distributed in the same area. Besides, trioecy was also discovered in several species. The white fruits with sweeter and more fragrant flavor than red fruits were first discovered in F. moupinensis (Franch.) Card. In situ, females and male plants of the same species were mixed together. The geographical distribution of the five tetraploid species native to China was surveyed and described in this paper.
