Abstract

Abstract:

In this paper，the diversity analysis，correlation analysis，principal component analysis，and cluster analysis were conducted by flower morphological characters of the main Camellia reticulata cultivars，so as to further optimize the current cultivar classification method. The results indicated that among the nine morphological characters，the highest coefficient of variation and diversity index H were stamen morphology（tubular，fascicular，or petaloid），followed by the stamen number，petal color and petal number. The number of stamens was significantly negative-correlated with the number of petals，while the assignment of stamen morphology was significantly positive-correlated with the number of petals. The first principal components was the comprehensive character represented by stamen number（contribution rate of 46.88%），followed by the petal color（27.55%），and the petal length/width（25.57%）. A total of 100 C. reticulata cultivars were clustered into three clades. The cladeⅠhad 26 cultivars，whose stamen bases were tubular. The cladeⅡincluded 49 cultivars，with fascicular stamen bases. The clade Ⅲ involved 25 cultivars，which had petaloid stamens or few stamens but did not appear as bundles. Based on the above results，a new classification method for the C. reticulata cultivars by using stamen morphology was proposed，namely（1）tubular stamen cultivar group of C. reticulata，（2）fascicular stamen cultivar group of C. reticulata，and（3）petaloid stamen cultivar group of C. reticulata. Apart from their ornamental purpose，the tubular stamen cultivar group is also an excellent germplasm for oil use.

Key words: Camellia reticulata, flower character, cultivar classification, cultivar group, cluster analysis
