Abstract: Based on investigation and analysis of 11 natural pupulations of Pistacia chinensis Bunge in China,morphological variation and diversity of pupulations were studied. Variation of all 18 characteristics are significantly different among and within populations. CV among phenotypic characteristics is markably different,varying from 4.249% to 27.31%. CV of fruit traits is minimum,which is controlled mostly by genetic factors. Average phenotypic differentiation coefficient (Vst)is 22.27%,indicating that the genetic variation within population is the main sources of genetic diversity. The 11 populations are classified,according to cluster analysis,into 4 groups. Besides 100 fruit weight,1000 grains weight and seed length,there was no significant relationship between phenotypic characteristics with geographic and ecological factors,but as longitude and latitude increase,the most fruits,seeds,leaves traits increase.

Key words: Pistacia chinensis Bunge, natural population, phenotypic diversity
