利用AMMI模型分析草菇区域品比试验研究

Preliminary Study on the Regional Variety Comparison Test of Volvariella volvacea by AMMI Model

借助加性主效应乘积交互作用(AMMI)模型分析草菇(Volvariella volvacea)6个品种在漳州地区的区域栽培试验结果。结果表明,不同品种间的产量表现达到了极显著差异;本次试验区的不同环境对产量的影响不显著;但互作效应主成分较好地解释了品种与环境的交互作用,IPC1与IPC2的P值分别达到极显著水平和显著水平。品种G3稳定性最好,品种G1在试验地点E1中具有特殊的适应性,同样品种G2在试验地点E2、E5和品种G4在试验地点E3、E4栽培可达到较高的产量,产量的综合分析结果表明,产量由高到低的顺序为品种G2、G1、G3、G4、G6、G5。

The AMMI model was used to analyze the result of regional cultivation experiment of six varieties of Volvariella volvaeea in Zhangzhou. The results showed that there were significant differences in yield performance among different varieties, and the effects of different environments on yield were not significant in this experiment area. However, the principal component of interaction could explain the interaction between variety and environment. The P values of IPC1 and IPC2 reached very significant level and significant level, respectively. The variety G3 had the best stability, the variety G1 had special adaptability in the test site El, the variety G2 in the experiment place E2 and ES, the variety G4 cultivated in E3 and E4 could reach higher yield. The result of comprehensive analysis of the yield showed that the order of yield from high to low was G2, G1, G3, G4, G6, G5.
