Twenty-seven genotypes and three varieties of wheat were grown in four locations in the medium and low plains since June-October 2009. The experiments were arranged using a randomized complete block design repeated three times. Analysis of variance performed at each location followed by a test of homogeneity of error range, the combined analysis of variance and yields stability analysis. Genotype x environment interaction significantly affecting yield. Stable genotypes and widely adaptable across locations were G-1 (1.94 t.ha -1 ), G-20 (1.24 t.ha -1 ), H-14 (1.85 t.ha -1 ), H-19 (1.59 t.ha -1 ), H-20 (1.69 t.ha -1 ), H-21 (1.48 t.ha -1 ), 162 (1.62 t.ha -1 ), 80 (1.63 t.ha -1 ), 82 (1.78 t.ha -1 ), 91 (1.49 t.ha -1 ), and 142 (1.45 t.ha -1 ). Genotypes adapted in productive environment were G-18 (1.23 t.ha -1 ), G-19 (1.63 t.ha -1 ), 185 (1.30 t.ha -1 ), 40 (1.33 t.ha -1 ) and 42 (1.52 t.ha -1 ). Genotypes adapted in marginal environments were 28 (2,22 t.ha -1 ), H-1 (1.61 t.ha -1 ), H-8 (1.65 t.ha -1 ) and H-16 (1.68 t.ha -1 ). Genotype was selected as an improvement material in the wheat breeding in medium and lowland of tropical regions.   Keywords: wheat selection, tropical, yield stability and adaptability
