Abstract

Multi-environments trials are effort in agriculture research to identify superior cultivars by examining adaptability of many genotypes of a cultivar in different environments. The expectation fiom these multi-environments trials is to find genotypes which highly adaptive in many environments (stable genotypes) and genotypes which only adaptable in certain environments (specific genotypes). Statistical method generally used for analysis of stability towards multi-environmeilts trials is AMMT (Additive Main Effect and Multiplicative Interaction) analysis. This method combines additive analysis of variance for treatments main effect and principal components analysis for interaction effect. Multi-responses become a special problem in AMMI analysis since this analysis can only works in single response. Thus, in many years analysis for multi-environments trials merely focused in one single response. There are infomation unexplained by rely on one only response.
