Abstract: More than 300 state- and provincial-level tea plant cultivars have been selected according to the agronomic traits in our country. However, few studies about the selection of eco-economical cultivars through comprehensive value method was reported. In this study, to screen optimal tea plant cultivars suitable for eco-economic strip-green tea, 24 tea cultivars were evaluated using Delphi and Analytic Hierarchy Process (AHP) methods. A comprehensive evaluation system containing 6 first-level indicators and 19 secondary indicators was formed based on the experts’ evaluated scoring and suggestions by a comprehensive discussion. Among them, the experts’ positivity degree of the first two rounds based on Delphi method were 82.5% and 100%, respectively. The degrees of experts’ authority were 0.93 and 0.90, respectively. The Coefficients of Variation were 0.19 and 0.16, respectively. While the Kendall’s W were 0.296 and 0.358, respectively (P<0.05). The weights of the first-level indicators were 0.364, 0.204, 0.128, 0.108, 0.124 and 0.072, respectively. The weights of secondary indicators were between 0.101-0.805 (all parameters were passed the consistency test). Among them, the expert positivity, degree of expert authority, Coefficient of Variation and Kendall’s W of the final round were 100%, 0.91, 0.36 and 0.11 (P<0.05), respectively. In summary, ‘Longjing Changye’, ‘Shuchazao’ and ‘Juhuachun’ ranked the top three, with scores of 3.714, 3.624 and 3.581, respectively.
