摘要	Based on the International Camellia Register (ICR), an analysis of 1616 cultivars of Sasanqua that were registered in 2022 and earlier was conducted. This analysis focused on the resource and biological characteristics of the cultivars. Additionally, a trait diversity analysis, principal component analysis, and cluster analysis of 118 cultivars that had complete morphological records were performed. The fi ndings revealed a rich diversity of Sasanqua cultivars, with Japan, the United States, and Australia being the main sources. The primary fl ower color was red, followed by multiple colors, white, and rare colors. The predominant fl ower forms were single -petal and semi -double -petal, with a limited number of formal double -petal forms. Elliptical leaf shapes were the most common, and the predominant leaf colors were green and deep green. The fl owering period mainly corresponded to early fl owering cultivars. The phenotypic diversity index ( H ) of the 118 cultivars ranged from 0.31 to 1.84. The fl ower diameter exhibited the highest H value (1.84), whereas leaf shape had the lowest H value (0.31). The coef fi cient of variation ( CV ) ranged from 21.67% to 71.81%, with the fl ower diameter having the smallest CV (21.67%) and petal number having the largest CV (71.81%). The fi rst three principal components, which accounted for a cumulative contribution rate of 62.49%, effectively represented most of the information regarding the seven trait indicators of the different cultivars. Furthermore, a cluster analysis was conducted based on the fl ower form, diameter, petal numbers, and other characteristics of the various cultivars. The 118 cultivars were divided into three groups. The fi rst group could be used for breeding single -petal fl ower cultivars, whereas the third group exhibited a larger number of petals and could be used for breeding double -petal fl ower cultivars.
