Wild Begonias in Guangxi are rich in resources,which have great prospects for development and application.Through the investigation and cultivation experiments of wild Begonia in Guangxi,and by using the Analytic Hierarchy Process(AHP) and the Entropy Weight Method(EWM),this paper comprehensively evaluated 60 species of wild Begonia in Guangxi to provide scientific basis for the introduction,domestication and gardening applications of Begonia.The evaluation system consisted of ornamental characteristics,biological characteristics,development potential and 16 evaluation factors.This study found that:1) 8 species were Class I,such as Begonia umbraculifolia,which had high ornamental value,strong resistance,wide range of suitability,and various applications.2) 14 species were Class II,such as Begonia ferox,which had high ornamental value,strong adaptability,and simple maintenance,with good development potential,but slightly inferior ornamental value.3) 18 species were Class III,such as Begonia austroguangxiensis,which had simple maintenance,strong growth potential,general development and application value.4) 13 species were Class IV,such as Begonia daxinensis,which had low adaptability.They did not have advantages in garden promotion and application,but could show their value in specific areas.5) 7 species were Class V,such as Begonia chongzuoensis,which had low garden application value and poor adaptability.They could be preserved in the gene pool as germplasm resources.The comprehensive evaluation system of wild Begonia resources established in this study has important theoretical and practical significance for the development and utilization of wild Begonia resources in Guangxi and even in China.
