Cluster analysis of environments based on grain yield of 84 hybrids from 11 lines and seven testers and seven checks grown at 10 stress and non-stress environments in Zimbabwe. Optimum environments were 1 = ART Farm; 2 = CIMMYT; 4 = RARS; 7 = Gwebi. Managed LN environments were 3 = CIMMYT LN; 6 = DR&SS and combined heat and drought environments were 8 = Chiredzi; 10 = Chisumbanje. Well-watered environments were 9 = Chiredzi; 11 = Chisumbanje.
