Evaluation on Adaptability and Stable Yield Capacity of Andan 3(a Hybrid Maize Variety)

The adaptability and stable yield capacity of Andan 3 were evaluated by using the conventional analysis method,and high and stable coefficient method based on the data of Guizhou regional tests during 2001-2006 to provide a reference for guiding its large acreage production and maize breeding.The results showed that there was no significant difference in its yield between different regions and between different years,the variance coefficient,standard deviation and environment parameter of its yield were lower than those of other varieties and its stable coefficient was the highest in the same group,which indicates that Andan 3 is of the better adaptability and stable yield capacity in different ecological and production environments of Guizhou province.
