| 中文摘要: |
| 采用GGE双标图对2010—2011年贵州省马铃薯区域试验中11个马铃薯参试品种在5个试点的产量和农艺性状进行分析，内容包括株高，单株块茎数，单株主茎数，单株块茎重量。结果表明，在参加马铃薯区试的11个品种中，品种（系）的丰产性表现较好的是G9（威薯001）、G2（宣薯2号）、G4（2005-1）、G6（0402-7）、G7（0402-2）、G5（W04-36），丰产性表现较差的是G8（盘薯1号），G10（黑美人）。品种（系）稳定性方面， G6（0402-7），G8（盘薯1号），G5（W04-36）的稳定性较好，G11（米拉）稳定性最差。总之，品种G5（W04-36），G6（0402-7）稳定性、适应性与丰产性表现良好。参加区试的5个试点中，区分力较强的试点为E2（毕节），E1（安顺），E3（凤冈），区分力较弱的试点为E4（六盘水），E5（威宁）。在代表性方面，试点E1（安顺），E4（六盘水）具有较强的代表性，试点E3（凤冈）的代表性最弱。所以，既具有强区分力又具有代表性的试点为E1（安顺）。 |

| A GGE-biplot analysis was employed in this research to examine the agronomic traits including stem height, tuber quantity per plant, stem quantity per plant, and tuber fresh weight per plant of 11 potato varieties in regional trials of Guizhou province during 2010—2011. G1-G11 were designated for representations of these eleven cultivars and E1-E5 were used for the five testing sites, respectively. The yield data of eleven potato cultivars from five testing sites were analyzed. The results indicated that the yield performances of G9 (Weishu 001), G2 (Xuanshu#2), G4 (2005-1), G6 (0402-7), G7 (0402-2), and G5 (W04-36) were higher than others. Whereas, cultivars G8 (Panshu#1) and G10 (Heimeiren) had the lowest yield performance. The cultivars G6 (0402-7), G8 (Panshu#1), G5 (W04-36) were more stable than others and G11 (Mira) had lowest stability among all cultivars. Taken together, the cultivars G5 (W04-36) and G6 (0402-7) were better in stability, adaptability and yield performance. Among the five test sites, E2 (Bijie), E1 (Anshun), and E3 (Fenggang) had better differentiations than others. E4 (Liupanshui) and E1 (Anshun) were typical representations of the overall testing sites but E3 (Fenggang) had the lowest representativeness. E1 (Anshun) had the best differentiation and representativeness among five testing sites. In summary, GGE-biplot was one of the reliable methods that breeders could use for analyzing and evaluating the potato yield performance and agronomic traits in regional trials. |
