  Comparison of Univariate and Multivariate Models to Analyze Stability of Common Bean (Phaseolus vulgaris L.) Genotypes in Ethiopia
  Author(s): Demelash Bassa*, Fekadu Gurmu and Hussein Mohammed
  
  Data of sixteen Andean red common bean genotypes were evaluated across six environments using seven univariate and two multivariate models to study Genotype by Environment Interaction (GEI) and stability in Ethiopia. There was significant (P<0.01) genotype, environment and GEI that necessitated estimation of the stability of the genotypes. According to the multivariate analysis of Additive Main Effects and Multiplicative (AMMI), Red kidney, DAB 478 and Melkadima were stable. According to Genotype plus Genotype by Environment (GGE) interaction bi-plot analysis, DAB 544, Red kidney, DAB 478, DAB 532 and DAB 478 were found stable. The univariate models identified stable genotypes DAB 478 and DAB 544 in common whereas the multivariate models AMMI and GGE identified best performing and stable genotypes Red kidney and DAB 478 across the six test environments. Therefore, one of the five u.. View more»
