Abstract

Abstract:

In this study,the drought and waterlogging tolerance and their stability across different trials were evaluated by principle component analysis,membership function,cluster analysis,and additive main effects and multiplicative interaction（AMMI）model for 54 tea chrysanthemum accessions at seedling stage. The results showed that the average coefficient of variation for drought and waterlogging tolerance were 25.21% and 33.71%,respectively,across two trials in June and July. The principle component analysis extracted each four main components from ten drought and waterlogging-related traits that could explain 81.36% and 80.52% of phenotypic variation,respectively. The membership function value-based clustering analysis grouped the investigated tea chrysanthemums into four drought resistance types（resistant,moderate resistant,not resistant,and susceptible）and four waterlogging tolerant types（tolerant,moderate tolerant,not tolerant,and susceptible）,and significant differences were observed among different tolerance types. A total of seven drought and five waterlogging tolerant accessions were excavated,and the stability of drought tolerance for the seven accessions were sorted as‘Fubaiju’> ‘Chuju’> GH7-2 >‘Huang Xiaoxiangju’> HC6-12 >‘Jinju 3’> CH,while the stability of waterlogging tolerance of the five accessions were sorted as GH9-33 > GH7-2 > GH7-32 >‘Hangbaiju’> CH. In addition,CH,GC1-16,‘Hongxinju’,and‘Chuju’showed relatively strong tolerance to both drought and waterlogging stresses based on the AMMI analysis.

Key words: chrysanthemum, tea, germplasm resources, water stress, resistance evaluation, principal component analysis, cluster analysis, AMMI model
