Evaluation on the phenotypic diversity of Calamansi (Citrus microcarpa) germplasm in Hainan island.

ABSTRACT: Calamansi or Philippine lime (Citrofortunella macrocarpa) is an important crop for local economic in Hainan Island. There is no study about Calamansi germplasm evaluation and cultivar development. In this study, Calamansi data were collected from 151 of Calamansi seedling trees, and 37 phenotypic traits were analyzed to investigate their genetic diversities. The cluster analysis and principal component analysis were conducted aiming to provide a theoretical basis for the Calamansi genetic improvement. The results of the diversity analysis revealed: (1) the diversity indexes for qualitative traits were ranged from 0.46-1.39, and the traits with the highest genetic diversity level were fruit shaped and pulp colored (H' > 1.20); and the diversity indexes for quantitative traits ranged from 0.
