Selection of quantitative variables and classification of 22 accesions of shrubby bean (Phaseolus vulgaris L. )
Evaluation of 22 collections and three tests of shrubby beans Phaseolus vulgaris L. From the germ plasm bank of the Colombian Corporation of Agricultural Research (Corpoica), allowed the selection of variables to discriminate the existing variability and to identifier the besta ccesions by means of quantitative morphological parameters and yield components. Variables with high heredabilitywere chosen based on repetibility coefficients graterthan one (Goodman and Paterniani,1969); and as a result, 14 varieties out of 24 were selected. Analysis conduced by principal components showed that the first three components explained 88.49% of the total variation. Characters such as days to flowering, days to harvest, weight of 100 seeds, seeds for pod, length and wide of pod, canopy cover, number of knots, length of epicotile and hypocotile explained most of the total variation collections from the mesoamerican pool :Antioquia 2l (Tenzano), Cauca 34 and Tolima 16, aswell as the Andeanpool : Perú5 { PorotoLargo) and Cundinamarca 148, presented the best agronomic performance and high genetic variabiliti and as a result, these collections were considered outstanding as source of genetic variability and for improvement programs.
