| Abstract: |
| The high and stable yield ability of 7 varities of dry-land wheat in the regional test in north part of China was studied by using the methods of high-stable coefficient, parameter of adaptability and coefficient of variation. The results show that the high-stable coefficient is prior to the other evaluation methods. Jintai 170, Chang 6878 and Longyuan 935 are the three recomended varieties with high and stable yield ability, in which Chang 6878 has a high drought resistance, and Jintai170 is a strong-food variety. |
