Origin & Breeding History: 'Kengo' (experimental designation D165315) originated from the cross between G 53-T1 and 'Novella', with a subsequent backcross to 'Novella', conducted in 2004 in Enkhuizen, Netherlands. In 2004, the BC1F1 and BC1F2 generations were planted. In 2005, selections made from BC1F3 were selfed. The BC1F4, BC1F5 and BC1F6 generations were planted from 2005 to 2006 and in 2007, selections made from the BC1F7 were selfed. In 2008, the BC1F8 generation was planted and in 2009, the BC1F9 was bulked as breeder seed. Selection criteria was based on downey mildew, powdery mildew, Pea Enation Mosaic Virus and Fusarium (Race1) resistances, adaptation, yield, leaf type, stem fasciation, seed type and maturity class.
Tests & Trials: The detailed description of 'Kengo' is based on the UPOV report of Technical Examination, reference number ERW1169, purchased from the Naktuinbouw in Roelofarendsveen, Netherlands. Two trials were conducted in one growing cycle, at the Naktuinbouw in Roelofarendsveen, Netherlands and at the Central Institute for Supervising and Testing in Agriculture, Brno, Czech Republic in 2017.
