Dataset for: Stability analysis for nutritional contents (Vitamin C) on 40 native potato cultivars

Knowledge of genotype by environment interaction effects on the micronutrient concentrations of different genotypes is needed to identify cultivars that show high and stable concentrations and to inform breeding and selection schemes. Stability analysis for micronutrient content has been applied to biofortification and varietal dissemination strategies.

Forty native potato cultivars were evaluated to: assess the magnitude and nature of Genotype (G), Environment (E), and GxE interaction effects for Vitamin C (Ascorbic Acid) in the tropical highlands of Peru and study the contribution of soil fertility to the micronutrient content of potato tubers. Tubers were taken from plots grown in randomized complete block designs with three replications of one hill per plot in each of 6 sites of the central Peruvian Andes in 2010: Ccasapata (3765 m.a.s.l); Sotopampa (3754 m.a.s.l); Ccollpaccasa (4067 m.a.s.l); Conayca (4178 m.a.s.l), la Victoria (3265 m.a.s.l) and Rangra (3323 m.a.s.l).
