Abstract: With ten grape rootstocks cuttings as materials, the physiologicals and biochemical indicators, like germination rate, rooting rate, relative conductivity, index of brown,relative water content, malondialdehyde, free proline, starch were measured after the cuttings were treated with -10℃, -15℃, -20℃, -25℃, -30℃, -35℃, and untreated cutting as control. The semi-lethal temperature of grapevine rootstocks was calculated with the relative conductivity by the Logistic equation. The data was treated by cluster analysis, correlation analysis and principal component analysis for their comprehensive evaluation of cold tolerance. Through the evaluation of principal component analysis and semi-lethal temperature, the cold resistance of ten grape rootstock was‘Beta’>‘101-14’> V. amurensis×V. riparia‘No.1’>‘Teleki 5A’>‘Teleki 5BB’>‘188-08’> V. amurensis×V. riparia‘No.3’>‘Teleki 5C’>‘Selection Oppenheim No.4’>‘Teleki 8B’.
