Study on the method of identical relation analysis among breeding target characters;

By these clusters the province has been divided into 4 breeding regions and each region s breeding targets have been confined.

According to the climatic features and productive level of winter wheat in this region, it puts forward the major breeding target of winter wheat in the 10th five-year program and the years ahead, the yield of the arid fertile land is 3,500-5.

It studied the development of breeding goal in two stages 1990-1998 and 1999—2006 from the changes of yield, ears per mu, kernels per ear, 1000 kernels weight of the participation variety, CK materials, and the first three places in regional experiment over late 17 years in Henan Province.
