基于HA-GGE双标图的甘蔗试验环境评价及品种生态区划分
Evaluation of Sugarcane Test Environments and Ecological Zone Division in China Based on HA-GGE Biplot
摘要
Abstract
The yield data of 24 sugarcane cultivars grown at 14 locations were analyzed in combination of analysis of variance and heritability-adjusted GGE (HA-GGE) biplot to study the genotype (G), environment (E), and genotype×environment (GE) effects on yield variation. Besides, the 14 test locations were evaluated for their discriminating ability, representative ability and desirability index, and grouped into ecological zones based on the GGE biplot patterns. The results showed that the effect of envi-ronments on yield was higher than that of G and GE, and the genotype by location interaction was the greatest while genotype by year interaction the least within GE. The GGE biplot analysis revealed that Suixi of Guangdong Province and Chongzuo of Guangxi Province were the two most ideal test locations for developing and/or recommending cultivars for the whole region. In contrast, Laibin and Liuzhou of Guangxi Province were undesirable for selection and variety recommendation for the whole re-gion. The other relatively desirable test locations included Fuzhou and Zhangzhou of Fujian Province, Zhanjiang of Guangdong Province, Baoshan, Lincang, and Ruili of Yunnan Province, followed by the four less desirable test environments, Baise and Hechi of Guangxi Province, Lingao of Hainan Province and Kaiyuan of Yunnan Province. According to the results from HA-GGE analysis, the sugarcane ecological zones in China could be divided into three subregions, the first is the ecological zone of south-ern China inland, represented by Baise, Hechi, Laibin and Liuzhou of Guangxi Province, the second one is the ecological zone of southwest plateau, represented by Baoshan, Kaiyuan, Lincang and Ruili of Yunnan Province, and the third one is the ecological zone of coastal southern China, represented by Fuzhou and Zhangzhou of Fujian Province, Zhanjiang and Suixi of Guangdong Province, and Chongzuo of Guangxi Province. The present study fully displayed the successful application of HA-GGE biplot in trial environment evaluation and also provided the theoretical basis for the decision-making in ecological zone division.关键词
