Previously trialed under pre-commercial designation DRTH1027. Characteristics are based on a 2-year crop cycle in Canada (2019 and 2020) and trial data from the Netherlands (2020).

Anticipated Disease Resistance Package
- HR: ToMV:0-2/ToTV/Ff:A-E/Fol:0,1/For/Va:0/Vd:0
- IR: On/Ma/Mi/Mj
- Given its strong vigor and its vegetative start, this variety is suited to long crop cycles. However, though it was developed for longer cycles, it is possible for it to go non-grafted for short cycles due to its resistance to Fusarium crown and root rot and Verticillium wilt.
