基于GGE双标图对‘豫谷28’的丰产稳产性及适应性分析

Analysis of High Yield Stability and Adaptability of 'Yugu28' Based on GGE Biplot

为准确评价谷子新品种‘豫谷28’的丰产稳产性和适应性,利用其参加2015-2016年国家谷子品种区域试验(华北夏谷区常规组)的产量数据,运用GGE biplot双标图对其进行分析。结果表明:2015年、2016年‘豫谷28’分别比对照增产9.43%和8.82%,GGE双标图分析显示:‘豫谷28’在平均环境轴上的垂足较靠近正方向,表明其丰产性能优良;与平均环境轴垂直的轴距离平均环境轴较近,表明其稳产性能较好;在适应性功能图扇形区中所处位置较靠近坐标轴原点,表明该品种的适应性较广,是谷子生产上具有推广价值的优良品种,适宜在河南、山东、河北等相似生态区夏播种植。

In order to accurately evaluate the high and stable yield and adaptability of the new millet variety 'Yugu28',the yield data of the national millet variety regional trial(conventional group in summer millet area of North China) in 2015-2016 were used for analysis by using the GGE biplot double plot.The results showed that 'Yugu28' increased by 9.43% and 8.82% compared with the control in 2015 and 2016,respectively.The analysis of GGE double plot showed that the vertical of 'Yugu28' on the average environmental axis was closer to the positive direction,indicating that its high yield performance was excellent;the axis perpendicular to the average environmental axis is close to the average environmental axis,indicating that its stable production performance is good;the position in the sector of the adaptive function map is closer to the origin of the coordinate axis,indicating that the variety has a wide adaptability,is a good variety with promotion value in millet production,and is suitable for summer planting in Henan,Shandong,Hebei and other similar ecological areas.
