| 中文摘要: |
| 采用GGE双标图将西北旱区马铃薯品比试验中的42个参试品系的产量、株高、主茎数、单株块茎数、单株薯块质量、商品薯率等农艺性状展示在双标图中进行综合分析。结果表明，在参加马铃薯品比试验的42个品系中，G38（0903-111）与产量和单株薯块质量关系相互作用大；G16（0904-25）、G30（0904-51）、G31（0773-9）、G35（0773-3）与主茎数、单株薯块数相互作用大；G1（0913-27）、G2（0911-101）、G6（0929-6）、G9（0904-75）、G20（0907-25）、G23（0904-11）、G24（0904-15）等品系与株高和商品薯率的相互作用较大。表现较好的品系有G38（0903-111）、G16（0904-25）、G31（0773-9）、G1（0913-27）等，其中品系G38（0903-111）综合表现最好。参加品比试验的6个农艺性状中，产量和单株薯块质量相比其它农艺性状，具有很强的代表性，能够准确反映出试验各品系的表现特性。单株薯块数和商品薯率对各品系表现的区分力强。 |

| 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. |
