An analysis of regression
among the genotypes from the same crop was performed and the
R2 values were obtained.High correlations between antioxidant activity
and total phenolics (R2 > 0.7) were obtained for genotypes
of sweet potatoes, peaches, and mashua and oca tubers, while low
correlations (R2 < 0.7) were obtained for plums and native potatoes
from Per ´u.
