Abstract

Abstract:

An experiment was conducted to analyze the morphological variation in terms of 12 phenotypic traits，including height of plant，length of spike，length of flag leaf，width of flag leaf，length of spikelet et al，using 20 natural populations of Psammochloa villosa. F value of 12 trait populations was 1.832?8.958，which reached a significant or extremely significant level，the phenotypic traits of different populations of P.villosa were widely varied，and the degree of variation was different. By principal component analysis，the first four principal components represented 82.277% of the morphological diversity. The PCA results indicated that the length of flag leaf，width of flag leaf，length of glume and length of spikelet were the main factors leading to morphological variations of different populations. When the genetic distance is 20.5，20 natural populations of P.villosa could be divided into 2 groups by UPGMA cluster analysis，and the phenotypic characters were not clustered according to the geographical distribution of the populations.

Key words: sandy plant, Psammochloa villosa, phenotypic trait, morphological variation, euclidean distance
