Notes:
Summary Four methods were used to determine stability and adaptation of sweet potato (Ipomoea batatas L. Lam.). Data from 14 sweet potato clones evaluated over 14 environments were used. Regression coefficients provided little information with regard to stability but did provide information on response of individual clones. Stability parameters using three of the four methods were highly correlated. The fourth presented different ranking patterns of stability than the other methods. However, the top five stable clones identified by the four methods were almost the same. Two methods were more effective and convenient in discriminating sweet potato clones based on their stabilities. Clones W151, ‘Resisto’, and W192 were more stable for no. 1 root yields. W151 and W192 were also stable for total root yields.
