Abstract

Abstract: Q\|cluster analysis and R\|cluster analysis were used to examine the 37 morphological characteristics of flower and fruit of 47 pummelo cultivars in Hunan Province， and the 37 morphological characteristics were analyzed with principal component analysis of SPSS 170 software. The results showed that the 47 pummelo cultivars could be classified into 6 groups based on Q\|cluster analysis， and the 37 morphological characteristics could be divided into 6 groups as well according to R\|cluster analysis. The principal component analysis showed that 37 morphological characteristics could be integrated into 12 principal components（PC） and their additive contributing rate amounted to 8158%， and 32 major discriminating characteristics in relation to pummelo flower factor and fruit factor were selected according to the relativity between 12 PC and characteristics.
