| A morphophysiological characterization of 19 accessions within an artichoke germplasm collection was conducted with the aim of determining genetic variability and to select materials suitable for in natura consumption to be used in genetic breeding. The collection was composed of commercial accessions, materials collected in South Brazil, and of foreign origin. Twenty quantitative, five multicategorical and two binary traits were evaluated. Quantitative data were submitted to a multivariate analysis. Genetic variability was observed for almost all characteristics. The traits with the greatest relative contribution to genetic divergence, which accounted for 79.54% of the variability, were as follows: the thickness and diameter bottom, bottom fresh mass/head... |
