Evaluation of Cotton Regional Trial Environments Based on HA-GGE Biplot in the Yangtze River Valley
摘要
Abstract
The latest heritability adjusted GGE (HA-GGE) biplot analysis was adopted to evaluate cotton regional trial environments (trial locations) in terms of the discriminating ability, representative ability, desirability index and superiority index for cotton lint yield selection in 27 independent sets of cotton variety trials in the Yangtze River Valley during 2000-2010 periods. The results showed that Huanggang, Nanjing and Jinzhou were the most ideal trial environments and therefore were the most effective locations for developing and/or recommending cultivars for broad adaptation selection in the target region. However, Shehong, Jianyang, Xiangyang and Nanyang were not desirable for cotton lint yield selection in the whole regions. The desirable test environments were all located in the middle and lower reaches of the Yangtze River Valley, while among the undesirable test environments Nanyang and Xiangyang were located at the inland Nan-Xiang Basin bordering with the Yellow River Valley in the north, where the first frost came early and temperature declined sharply in the late autumn, and Shehong and Jianyang were located at the mountainous Sichuan Basin in the west area, where cotton planting density was higher and cotton matured earlier. Therefore, this article fully displayed the HA-GGE biplot application efficiency in regional trial environment evaluation and also provided the theory background for the decision-making in national cotton scheme implementation and cotton megaenvironment investigation in the Yangtze River Valley.关键词
