Abstract
The phenotypic variations of 17 populations of Catalpa fargesii f. duclouxii, theirs 7 phenotypic traits including fl owers branch length, upper calyx length, lower calyx length, corolla and fl ower diameter were investigated. The results show that there existed notable variations of phenotypic characters of f lowers within and among the groups, the differences of the 7 phenotypic traits reached an extremely signif icant level(P 0.01), the mean variation coeffi cient was 25.94%, the amplitude of variations of each characteristic of f lowers ranged from 7.85%～47.17%, the mean phenotypic differentiation coeff icients was 27.95%(14.92～ 42.15%), the variation within seventeen populations(72. 05%) was larger than that of among populations(27.95 %); the f lower traits were highly signifi cantly related with the latitude and longitude, and extreme signifi cantly with the altitude. According to the UPGMA cluster analysis, the 17 populations of C. fargesii f. duclouxii were divided into four groups.
