Abstract: It was by the rank analysis method that yield stabilities of winter wheat varieties attending the regional trials of north-middle part of Hebei province in the past six years have been evaluated so for. After ranking value of different varieties (H2), mean square value (S2), as well as environmental index (YM) were calculated, the stabilities and yield have been compared. Therefore, 22 new varieties were evaluated objected.
