The static stability,the average dynamic stability and the optimal dynamic stability were adopted to analyze the yield stability of wheat lines' in the south of Huang and Huai River during 2013-2014,respectively. The results showed Dehongfumai 8 and Xinmai 31 and Zhengmai379 in winter water group A,and Luomai 29 and Xumai0045 in winter water group B,as well as Zhongyuan 8 in spring water group put up the best static stabilities,the average dynamic stabilities and the optimal dynamic stabilities and high yields. This kind of varieties occupied 13. 6% of all. 17 varieties such as Cunmai8 put up high yields and general stabilities and they occupied 38. 6% of all. Varieties possessed high yield but poor stabilities occupied 15. 9% of all. The other varieties which had low yield and wicked stabilities occupied 31. 9% of all. Six varieties such as Xinmai31 were suggested to be the main varieties to be popularized in the south of Huang and Huai River. The research provided theory evidence for wheat breeding and suggestions were made for future revision of the new wheat varieties' marketing.
