Estabilidad fenotípica de arveja (Pisum sativum L.) en la zona productora de Nariño, Colombia

Introduction. The pea (Pisum sativum L.) is a legume crop of great importance for the peasant economy in the high Andean zone of the department of Nariño, Colombia. Most of the pea production in this department is marketed as fresh pods; however, it is necessary to strengthen the local dry bean market, which requires varieties adapted to regional conditions. Objective. To evaluate fifteen pea genotypes for phenotypic stability of dry grain yield, in the Nariño production zone. Materials and methods. Between 2013 and 2014, fifteen pea genotypes were evaluated in three Nariño environments. The experiments were established with a randomized complete block design and four replicates. The GGE biplot model was used for dry grain yield stability analysis. Results. In the analysis of variance across the three environments, there were significant effects (p
