Résumé
INRA hosted the national Jerusalem artichoke collection in Rennes and Clermont-Ferrand until 2005. It now takes place in Montpellier. The list of cultivar-clones and of wild accessions is provided as well as main data on expected yield, earliness, female fertility, and disease susceptibility to viruses and Oidium. Descriptions of some traits (anthocyanin, ramification, chlorophyll) were reported. Data was collected from a hydroponic experimental design which was set up with two repeats at Mauguio and Montpellier. The experimental yields are shown for nine clones chosen for agronomic production of tubers and the pictures of tubers are given.
