Diversity in local cultivars of Pisum sativum collected from home gardens in Sweden
Abstract Although one would assume that finding any local cultivars in home gardens in a modern society such as Sweden is unlikely, such cultivars were in fact found. More than 170 seed accessions of vegetables, pulses and other seed-propagated garden crops maintained in home gardens and dating back at least to the 1950s have been assembled following the nationwide ‘Seed Call’. Of these, 32 garden pea accessions were taxonomically characterized and compared with 43 accessions already present in the gene bank. In addition to morphological descriptors, SSR and retrotransposon-based iPBS markers were applied. Based on five SSR markers, potential duplicates could be located within nine pair/gro…
Morphological Characterization of Nordic Horseradish (Armoracia rusticana)
AbstractMorphological diversity was studied in 101 accessions of horseradish (Armoracia rusticana) collected from old gardens in Denmark, Norway, Finland and Sweden. The characterization work was performed over three years, where a total of 19 descriptors from the UPOV guidelines TG/191/2-2001 were recorded each year. The results showed high diversity among the studied accessions, both for leaf and rhizome characters. A morphotype with long leaves and a high leaf length/leaf width quota was the most common, but also elliptic and heart-shaped leaf types were found. Some characters showed stability over the years, although there were variations in the results. Correlations between descriptors…
