Abstract: The method of high-stable yield coefficient （YHSC） and meteorological fhetors stability coefficients-including light stabilization coefficient （LSCi）, temperature stabilization coefficient （TSCi） and rainfall stabilization coefficient （RSCi）-were used to analyze the effects of light, temperature, rainfall and high-stable yield of 22 adzuki bean varieties. The results showed significant difterenees between the YHSCs of difterent varieties The YHSC of HD05 （Jihong 16） was the highest, 58.6% higher than that of CK. The meteorological fhetors stability coefficients of different varieties also showed difterenees, LSCi of 15 varieties were higher than that of CK, TSCi of 13 varieties were higher than that of CK and RSCi of 3 varieties were higher than that of CK. According to the fhetors including LSC,TSC and RSC, the 22 adzuki bean varieties responses to environmental change were divided into 3 categories, sensitive response （2 varieties）, intelTnediate response（8 varieties） and stability response （12 varieties）, respectively. In addition, HD05 （Jihong 16）, HD16 （Xiaodou 5） and HD04 （Jihong 15） belonged to the intemlediate response type and had high-stable yield coefficients. This study can provide reference fbr varieties and germplasm screening of summer sowing adzuki bean in northwestern Shandong.
