算术平均法经常被用于评估甘蔗品种产量的稳定性和适应性,并用方差分析来估计区域试验的试验误差.然而,地点和年份的差异使品种的差异难以得到准确评估.为客观评价甘蔗品种的稳定性和适应性,本研究采用GGE双标图对2008—2009年我国甘蔗区域试验5个试点中的7个甘蔗品种试验数据进行分析.结果表明:福农30号为蔗茎产量高且稳产性高的品种,粤甘18号为含糖量高且性状稳定的品种,福农28号和云蔗99-91为高蔗糖分且性状稳定的品种,粤甘16号的蔗茎产量和含糖量最高,但稳定性一般;在各试点中,福建漳州和广东遂溪的代表性和鉴别力较强.GGE双标图分析为客观评价甘蔗参试品种的丰产性和稳定性提供了直观、有效的手段,为甘蔗新品种的鉴定与推广提供了科学依据.
Arithmetic mean method is often used to evaluate the stability and adaptability of sugarcane varieties, and the variance analysis is used to estimate the experimental error of the regional experiment.However, the difference of the location and the year makes it difficult to accurately evaluate the varieties.For the objective evaluation of sugarcane varieties The stability and adaptability of seven sugarcane cultivars in five pilot experiments of sugarcane regional in China from 2008 to 2009. The results showed that: High yield and stable varieties, Yuegan 18 is a high sugar content and stable traits, Funong 28 and Yunji 99-91 as high sucrose and stable traits, Yuegan 16 cane yield and The highest content of sugar, but the stability of the general; in each pilot, Zhangzhou, Fujian and Guangdong Suixi strong representation and discrimination .GGE double plot analysis for the objective evaluation of the high yield and stability of sugarcane varieties tested provided Intuitive and effective means for the identification and promotion of new sugarcane varieties provide a scientific basis.
