| 中文摘要:以2007-2008年甘肃省马铃薯区域试验的9个品种在7个试点的块茎产量为材料，利用基于Genstat的GGE双标图分析评价参试品种（系）的丰产性、稳定性、适应性以及各试点的代表性和区分力。结果表明，参试品种（系）‘陇薯9号’‘L0227-18’‘天薯10号’‘陇薯8号’的丰产性和稳产性较好；7个试点被划分为2个类型区域，在 2 个类型区域中表现最好的品种分别为‘陇薯9号’和‘陇薯6号’，安定、会川和临夏是比较理想的试点，具有较强的区分力和代表性。 |

| Abstract:In order to analyze the high yield, stability and adaptability of tested potato varieties(lines), discrimination and representativeness of testing sites, GGE biplot based on Genstat was used to evaluate tuber yield data of the regional trials during 2007-2008 in Gansu province. Nine genotypes were tested in seven testing sites. The result showed that ‘Longshu 9’‘L0227-18’‘Tianshu 10’ ‘Longshu 8’ of tested variety had high yield and better yield stability. Seven testing sites were grouped into two mega-environments, the best candidate varieties(lines) of potato for two mega-environments were ‘Longshu 9’ and ‘Longshu 6’, respectively. Among seven test environments, Anding, Huichuan and Linxia with better discriminability and representativeness were ideal testing sites to assess identify potato variety. |
