Correlation analysis results between selection criteria (STI, SSI, TOL, MP, YSI) and genotype mean yield under
non stress (YP) and under stress (YS1 and YS2) were shown in Table 2. It was elucidated that the parameter
selection STI and MP have significant correlation with YP, YS1, and YS2, in tuber yield, starch yield and tuber dry
