中文摘要:
      为分析区域试验参试组合的丰产、稳产性和适应性及各试验点的鉴别力和代表性,采用免费、开源的R语言GGEBiplotGUI程序包对2018年江苏省淮北区域试验18个品种(含对照郑单958)和10个试验点进行了分析。结果表明:10个试验点可分为3个 “小生态区”,其中丰县、铜山、邳州、沭阳为一个“小生态区”,淮安、睢宁、宿迁为一个“小生态区”,滨海、岗埠(位于连云港)、淮安金色天华为一个“小生态区”。瑞友288、HT736、X1601、Ly1666丰产性较好,其中瑞友288不但丰产性好,稳产性也好,其他三个组合稳产性稍差。综合各试验点的鉴别力和代表性,淮安、睢宁、沭阳三个试验点鉴别力强、代表性好;岗埠试验点、淮安金色天华试验点具有较强的鉴别力但是代表性较差;宿迁试验点具有较强的代表性但是鉴别力较差。
英文摘要:
      In order to evaluate the yielding ability and stability, and adaptability of different maize varieties, as well as the discrimination and representativeness of test sites in maize regional trial, the GGEBiplotGUI package of free and open source R language was used to analyze 18 varieties(including Zhengdan 958 as the control ) and 10 test sites in Huaibei, Jiangsu Province in 2018. The results showed that the 10 test sites were divided into three small "ecological zones", among which Fengxian, Tongshan, Pizhou and Shuyang were the first group, Huai'an, Suining and Suqian were the second group, Binhai, Gangbu farm of Lianyungang and Jingsetianhua of Huai'an were the third group. Ruiyou 288, HT736, X1601 and Ly1666 had high yields, among which the yield of Ruiyou 288 was high and stable, and the yields of the other three weren’t stable. The three test sites, Huai'an, Suining and Shuyang had good discrimination and representativeness. The test sites, Gangbu farm of Lianyungang and Jingsetianhua of Huai'an had strong discrimination but poor representativeness. The test site of Suqian had strong representativeness but poor discrimination.
