Field Evaluation of Twelve Clones of Oregano Grown in the Main Production Areas of Argentina: Identification of Quantitative Trait with the Highest Discriminant Value

Figure 2

Biplot plane formed by the two first principal components (CP1 and CP2), where the dots represent the 12 clones of oregano evaluated and the vectors, quantitative characteristics measured in Potrero de Garay (Córdoba). C₁-FCA: clone 1 C₂-FCA: clone 2, C₃-FCA: clone 3, C₈-FCA: clone 8; Me-Mza: clone “Mendocino,” Cm-Mza: clone “Compacto,” Cd-Mza: clone “Cordobés,” Cr-Mza: clone “Criollo,” Me-TS: clone “Mendocino,” NB-TS: clone “Negrito B,” VL-TS: clone “Verde Limón,” Ne-SJ: clone “Negrito,” LBL: longest branch length, IL: internode length, LA: leaf area, FW: fresh weight, LDW: leave dry weight, SDW: stem dry weight, L/S: ratio LDW/SDW, EO: essential oil content, *measured at 1st harvest (three month after sowing), **measured at 2nd harvest (one year after sowing).
