[Objective] The paper analyzed production adaptability and stability of 4 hybrids of castor, so as to explore the application method of AMMI model in variety evaluation. [Method] AMMI model and biplot were used to carry out stability analysis on 4 castor combinations in multi-point test during 2008 and 2009, and further evaluated the stability and adaptability of various tested combinations. [Result] AMMI model analysis showed that the singular values IPCA1 and IPCA2 in principal component axis of interaction totally explained 92.24% of the interaction variance. AMMI model not only maximizes the reflection on variation of interaction, but also can accurately analyze the adaptability and yield stability of varieties. [Conclusion] AMMI model integrates variance analysis and principal component analysis together, which improves accuracy compared with the traditional method. Even the adaptability of female line without fertility could be indirectly evaluated through the identification on the genotype and environment interaction effects in F1 generation.
