Diversidad morfológica del fréjol (Phaseolus sp. y Vigna sp.) distribuido en el sur de Ecuador: Implicaciones para su conservación, como resiliencia al cambio climático y para la seguridad alimentaria.

Abstract

Abstract: The present work was developed with the objective of studying the morphological and phenological diversity of three bean species (P. vulgaris, P. lunatus and Vigna sp.) Represented by 12 accessions from the UTPL seed bank and one commercial accession. We evaluated 52 quantitative characters, of which 32 are morphological and the rest belong to the phenological subscales. The data were subjected to multivariate analysis (Main Components and groupings). The evaluated accessions presented a wide variability with respect to the morphological characters, being the most representative those related to flowers, pods and seeds; which has allowed to clearly differentiate the materials of Vigna sp. of the Phaseolus. As far as phenological characterization is concerned, the most representative main scales are 10 % of open flowers, the first visible pods and 100 % of mature pods, resulting in the accessions of P. vulgaris and Vigna sp. have been the earliest materials, both in protected conditions and in the open field, respectively; a differentiation between species has been generated just like what happened with morphology.
