Abstract:

To accurately evaluate the adaptability of 19 tea cultivars in Hubei Province. In this study, the major agronomic traits such as survival rate, phenological phase, yield traits, ensory quality, and stress resistance were systematically analyzed by comparison with ‘Fudingdabaicha’ (CK), and the adaptability of different tea cultivars in Hubei Province was comprehensively evaluated by principal component analysis. Three principal components including yield - resistance factor, phenological phase factor and quality factor were determined, and the cumulative variance contribution rate was 76.96%. The composite scores of ten cultivars were higher than that of CK, of which ‘Chanong 98’, ‘Echa12’, ‘Shancha1’, and ‘Lanlixiang’ were the most suitable application area in Hubei or similar areas. The composite scores of nine cultivars were lower than that of CK, of which ‘Baiye1’, ‘Zhonghuang1’, ‘Caoxi1’, and ‘Niaowang106’ were not the appropriate application area in Hubei or similar areas.

Key words: tea cultivars, adaptability, principal components analysis
