| Abstract: |
| GGE-biplot was first used in this study for comprehensive analysis of agronomic traits of potato in the northwestern arid regions of China. The experimental results showed that there were closed interactions for G38(0903-111) with yield and tuber quality per plant; G16(0904-25), G30(0904-51), G31(0773-9), G35(0773-3) with main stem number and the number of tuber per plant; G1(0913-27)、G2(0911-101)、G6(0929-6)、G9(0904-75)、G20(0907-25)、G23(0904-11)、G24(0904-15) and other lines with plant height and potato commodity rate, respectively. G38(0903-111), G16(0904-25), G31(0773-9) and G1(0913-27) have good performance and the G38 (0903-111) has the best performance in the 42 potato lines. For the six agronomic traits participated in the experiment, yield and tuber quality per plant can accurately reflect the characteristics of the test lines compared with other agronomic traits and have great representativeness, the number of tuber per plant and commodity potato rate of each line has fine discrimination. |
