Fig. 1. Results of query for cultivar ‘Marion (USA)’ in database "Pedigrees of Oat Lines" (http://avena.agr.gc.ca). Passport data includes entry ID (specific to this database), a preferred name, alternate names, species information, cross date, origin, and a reference for the origin. Comments may include anecdotal information about performance, alternate pedigree information and any comments that the database curator feels might help with the interpretation of the data. References for names are documented separately from the reference for the origin, and these are provided as "ref" links beside each name. In this case, the preferred name ‘Marion (USA)’ has been designated by the database curator to distinguish this germplasm from another variety ‘Marion (Canada)’ which is clearly a distinct variety with a different pedigree. By default, each passport is accompanied by a three- or four-generation pedigree. The pedigree is presented in tabular format which can be copied and pasted into a spreadsheet. The final generation of the pedigree is staggered downward to save space in the table. The number of generations can be changed using the selector beside "Ancestry." Alternatively, the reverse pedigree of an entry ("Descendancy") can be listed.
