Abstract:Twenty phenotypic characters from 5 natural populations of Camellia tunghinensis Chang were investigated. The variations in most phenotypic characters among populations were larger than those within populations, in which the variations in 13 characters among populations, such as fruits weight and diameter, eg., were very significant (P＜0.01). The variance range of SMPF/FM was the biggest, and that of seed longitudinal diameter was the smallest. The differences in overall phenotype among populations were not significant. The variation coefficient of 5 populations was in order of SFSH1 (0.272)＞MJG (0.217)＞SFSH (0.207)＞SHL (0.190)＞DGL (0.170). The correlations between average height, plant diameter at basal and various phenotypes characters were not significant, but it existed among phenotypic characters.
