Abstract: In order to cope with the climate challenge of winter drought, frequent natural disasters in low altitude mountain areas, it is necessary to screen and evaluate the rapeseed varieties having more stable and stronger adaptive traits. As such, seven rapeseed varieties were tested in 4 different latitude areas in the warm year of 2012 and the cold year of 2015. [Method]By using grey relation analysis, multi-regression analysis, AMMI model and fuzzy clustering analysis, the yield and main agro economic traits of different varieties were compared. [Result] The results have illustrated that:(1) there is significant difference of correlationbetween the yield and main climate factors in cold year and warm year; (2) in AMMI model, the variance of gene type, interaction between gene and environment in warm winter are higher than those in cold winter, whereas the variance of environment in warm winter is significantly lower than that in cold winter; (3) in warm winter, the gene type, environmental variation, and the interaction between gene type and environment can significantly affect the yield, effective plant per unite area, pod number and silique number; whereas in cold winter, the interaction between gene type and environment can significantly affect yield, whole growth period, effective plant per unite area and silique number. [Conclusion]the rapeseed varieties of Yunhuayouzaoshu 1#, Huayou 6#, Yuhongyou 1# and Huayou 5# were recommended to grow in low altitude mountain areas, due to their excellent traits of good adaptability, stable and high yield in both warm and cold winter.
