Use of genetic resources from Jerusalem artichoke collection of N. Vavilov Institute in breeding for bioenergy and health security

The VIR Collection contains 313 varieties and hybrids of Jerusalem artichoke Heliantus tuberosus L. The material originated from several countries of America and Europe represents a potential source of valuable traits for breeding, including yield and precocity. Clones of 70 varieties and hybrids of Jerusalem artichoke from 11 countries were evaluated for yield and precocity. The selection of valuable for breeding accessions was carried out. As result of five years screening new perspective genetic sources of valuable commercial traits for breeding were singled out.
