      Powdery mildew is a worldwide major fungal disease for grapevine, which adversely affects both crop yield and produce quality. Disease identification is based on visible signs of a pathogen once the plant has already been ...
    • Integration of expert knowledge in the definition of Swiss pear core collection 

      Urrestarazu Vidart, Jorge Upna; Kägi, C.; Bühlmann, A.; Gassmann, Jennifer; Santesteban García, Gonzaga Upna; Frey, Juerg E.; Kellerhals, Markus; Miranda Jiménez, Carlos Upna (Nature Research, 2019)   Artículo / Artikulua  OpenAccess
      Core collections (CCs) constitute a key tool for the characterization and management of genetic resources (GR). When the institutions involved in GR preservation decide to define a CC, they frequently prefer to select ...
    • Oenological significance of vineyard management zones delineated using early grape sampling
