Analysis of the discriminating power of agro/morphological and biochemical descriptors in a sample of the Spanish collection of barley (Hordeum vulgare L.) Discriminating power of agro/morphological and biochemical descriptors in barley
A sample representative of the national collection of barley (Hordeum vulgare L.) has been evaluated with different agro/morphological and biochemical descriptors in order to determine their usefulness for discriminating accessions. Multivariate analysis performed on three sets of traits (agro/morphological traits, biochemical traits and agro/morphological plus biochemical traits) showed that, in general, the relationships between agro/morphological and biochemical descriptors were low. Cluster analysis revealed that the classification of the accessions by the agro/morphological data was different from the classification obtained according to the biochemical data, indicating that the two types of markers reflect different patterns of diversity. However, neither agro/morphological nor biochemical characters identified all the accessions as unique phenotypes. Conversely, all the accessions were individually separated using a combination of agro/morphological and biochemical traits since the two types of markers provided complementary information.
