In this paper, we analysed the variance of vegetal period of three provenances and fifteen families of Toona ciliate var. pubescens in Guanshan, Matoushan and Jiulianshan nature reserve in Jiangxi province. The result showed that ① heritability of height and diameter were 0.85, 0.57 respectively and there were huge variations among the three provenances; ②growth variations of fifteen families were obvious, and the average height and diameter of the experiented tree increased by 18.89% and 6.82% respectively, compared with those before experiment. Based on Duncan＇s new multiple range test, six superior individuals G6, J3, J1, G4, J2, G2 were screened.
