Assessment of Tuber Yield Stability and Adaptability of Some Elite Yam Genotypes in the Guinea Savannah Ecology of Northern Ghana

Figure 3

The average-environment coordination (AEC) view of GGE biplot to show the mean performance and stability of the genotypes. The biplots were based on scaling = 0, centering = 2, and SVP = 1. Genotypes: G1 = 95/0194, G2 = 95/18544, G3 = 95/18922, G4 = 95/18949, G5 = 95/19156, G6 = 95/19158, G7 = 95/19177, G8 = 96/00594, G9 = 96/02025, G10 = 96/02610, and G11 = Laribako; environments: E1 = Mbowura 2010, E2 = Lantinkpa 2011, E3 = Lantinkpa 2012, E4 = Yendi 2012, and E5 = Nyankpala 2012.
