将国内外引进的5个牛蒡品种分别布置在3个不同生态点种植,采用AMMI模型对影响牛蒡产量的基因型、环境、基因型与环境(G×E)互作进行了分析。结果表明:PCA1轴解释了92.91%的互作平方和,“白肌大长”、“东京白肌”属高产稳产型;“东京理想”产量较高,但稳定性较差;“柳川理想”稳定性较好,但产量一般;“地皇早生”产量一般,稳定性一般。从AMMI模型互作效应值可看出,桂林试点对品种的分辨力最强,合浦试点分辨力最弱。“白肌大长”具有广泛的适应性,“东京理想”、“东京白肌”在南宁具有特殊适应性。 Five burdock cultivars introduced at home and abroad were planted in three different ecological spots. The AMMI model was used to analyze the genotype, environment, genotype and environment (G × E) interaction of burdock yield. The results showed that the PCA1 axis explained 92.91% of the square of the interaction, “white muscle length”, “Tokyo white muscle” is a high and stable production; “Tokyo ideal” high yield, but poor stability; “Yanagawa ideal ” the stability is better, but the output is general; “emperor early birth ” The yield is general, the stability is general. It can be seen from the interaction effects of the AMMI model that the pilot of Guilin is the strongest in breed discrimination and the weakest of the pilot in Hepu. “White muscle long ” has a wide range of adaptability, “Tokyo ideal”, “Tokyo white muscle ” has special adaptability in Nanning.
