Abstract: 【Objective】The objective of this study is to lay a foundation for screening of the grape cultivars which are suitable for the protected cultivation environment.【Method】Twenty-two 5-year-old protected grape cultivars were used as experimental materials to study the adaptability of different grape cultivars under the protected environment and to make clear the important environmental factors which affect high yield in successive years of the protected grapes.【Result】The results showed that the grape cultivars with high-yielding capacity in successive years in the protected cultivation environment conditions have a better ability of resistance to low-light, but not necessarily strong resistance to low concentrations of CO2 and high temperature. Low light is the major environmental factor which affects high yield in successive years of the protected grapes, but low concentration of CO2 and high temperatures are not the major environmental factors.【Conclusion】Hongqitezaomeigui, Zizhenxiang, Centenial Seedless, Wuhezaohong, Hongbiaowuhe, 87-1, Cardinal, Pearl of Csaba, Otilia Seedless, Xiangfei and Hongxiangfei have a higher environmental adaptability and high ability of sustainable productivity. Low light is an important environmental factor which affects high yield in successive years of the protected grapes.
