| Abstract: |
| This paper analyses the high and stable production ability of 11 dry-land wheat varieties in the regional tests in east part of Gansu province in 20022004 by adopting the methods of regression coefficient, stability parameter and high and stable yield coefficient. The result shows: the high and stable coefficient is a simple and effective evaluation method prior to the others; Longyu 215 and Longjian 301 are high and stable in production ability, which are the best varieties to be extended in the dry-land in east Gansu province. |
