摘要:  用AMMI 模型双标图对国家第六轮甘蔗品种区域试验5 个试点的12 个甘蔗品种试验数据进行分析,研究甘蔗区试中不同品种的产量稳定性问题。结果表明,参试品种的6 个产量性状在品种间和地点间差异显著,品种与地点的互作效应差异显著;FN30、YG16 蔗茎产量和含糖量高,稳定性强,属于高产、稳产性较好的品种。AMMI 模型很好地解释了甘蔗品种产量性状的基因型效应、环境效应和GE 互作效应。

Abstract:  The yield stability and adaptability of twelve sugarcane lines in five locations at the sixth national regional trials were studied by using AMMI (additive main effects and multiplicative interaction) biplot method. The results showed that there were significant differences in six yield traits among genotypes and environments, so did the interaction effects between genotype and environment. FN30 and YG16 had high stem yield and sugar content with strong yield stability. However, the overall stability of the two sugarcane lines was not high, which indicated that they should be promoted in a certain region. AMMI model could clearly explain the genotype effect, environment effect and genotype-environment interaction effect on yield trait.
Key words:  Sugarcane  Biplot  Stability analysis  Line adaptability  AMMI model
