Abstract: The new wheat variety Xiaoyan22, which was approve by Shaanxi province and by nation, has two sister lines whose names are Xiaoyan22-2 and Xiaoyan22-3. The two sister lines are very similar in their agronomy properties,and possess many outstanding advantages, such as: Poly-spike and poly-grain, good fructification, high quality, high yield, strong resistance and wide adaptability etc. In addition they have been the most primer wheat variety planting in Shannxi province since 2000. This paper analyze systematically the difference of the two sister lines of wheat variety Xiaoyan22 by studying on agronomy properties, SDS-PAGE and A-PAGE, and SSR etc. The results were as follows: The similarities and differences of agronomy properties between the two sister lines are summarized, and both the characteristics bands form SDS-PAGE and A-PAGE patterns and 25 pairs peculiar primers form SSR to differentiate the two sister lines are all found out.
