Abstract: Comparison was made on seed and seed-coat weight, content of saponin of Sapindus mukorossi seed from 20 provenances. The result indicated that Changsha-2 of Hunan, Panzhihua of Sichuan, Sanming of Fujian, Changsha-3, Chengdu-2, Xiangyang of Hubei were better provenances. Plantation distribution of these plus provenances was implemented in 2012 in Tiantai, Zhejiang province. Prediction of mean single seed weight, seed-coat weight and saponin content from plantation would reach 3.6g, 2.18g and 79.56mg
