Dataset for selection of promising potato (solanum tuberosum L.) using multi-traits index

· The analysis of variance showed significant differences for most traits, except for the economic tuber weight and leaf width. · The correlation analysis exhibited the considerable positive association of tuber weight per plot with the traits of tubers per plot, tubers per plant, economic tuber weight, stem diameter, tuber diameter, and economic amount of tubers. · The MGIDI analysis successfully identified the highest heritability in leaf length (92.7%) and accumulated the PCA variance of 89.4%. The MGIDI analysis also succeeded in identifying the two leading potato genotypes (G7 and G11) with the desired traits profile.
