摘要:

为明确甜玉米不同品种在广东省区域试验中的丰产性与稳定性、各试点环境的代表性与鉴别力,以2018—2019年广东省甜玉米区域试验18个参试品种的产量性状数据为研究对象,利用GGE-biplot方法对其进行分析。结果表明,2018年试验中‘粤甜33号’、浙甜808’、‘新美甜816’在丰产性和稳定性表现位居前三,2019年试验中,‘粤甜33号’、‘华美甜468’、‘新美甜816’在丰产性方面居前三位,稳定性好的品种依次为‘粤甜33号’、‘粤甜16号’、‘正甜89’,2年试验‘粤甜33号’在丰产性和稳定性方面综合表现最好,其适应性也最强。各试点环境之间呈正相关关系,说明各试点均有较好的代表性,部分试点环境之间存在紧密正相关,广州和英德两个生态区分别是2018年和2019年理想试点环境,对品种有较好地环境鉴别力和代表性。

Abstract:

To clarify the high yield and the stability of sweet corn varieties, and the representativeness and the discriminability of the testing sites in Guangdong Province regional test, the yield data of 18 sweet corn varieties of 2018-2019 Guangdong Province regional test were analyzed by GGE-biplot (genotype main effect plus genotype-environment interaction). The results showed that ‘Yuetian 33’, ‘Zhetian 808 ’and ‘Xinmeitian 816’ in the test of 2018 were in the first three places in terms of high yield and stable yield. In the test of 2019, ‘Yuetian 33’, ‘Huameitian 468 ’and ‘Xinmeitian 816’ were in the first three places in terms of high yield, and ‘Yuetian 33’, ‘Yuetian 16’ and ‘Zhengtian 89’ had the best stability. ‘Yuetian 33’ had the best comprehensive performance, stability and adaptability in the two years’ test. There is a positive correlation among all test environments, indicating that they have good representativeness. A close positive correlation is found between some of the test environments, Guangzhou and Yingde ecological zones are the most ideal sites for 2018 and 2019, respectively, which have good environmental representativeness and discriminability for sweet corn varieties.
