Origin & Breeding History: 'DL Nevado' (experimental designation NPZ 18.7602) originated from the cross made between the varieties 'Tiffany' and 'DL Tesoro' at the Norddeutsche Planzenzucht breeding station in Hohenlieth, Germany in 2012. The variety was developed using the pedigree breeding method with isolation cages to maintain genetic purity. The line was selected and purity confirmed in 2015. Selection criteria included low vicine and convicine content, straw stiffness, maturity and protein content. In 2017, at the F10 and later generations, 'DL Nevado' seed was trialed in Morden, Manitoba and Edmonton, Alberta and was subsequently trialed in 2019 and 2020 in the Western Canada Faba Bean Cooperative Trials at 9 locations across Western Canada.
Tests & Trials: The comparative trials for 'DL Nevado' were conducted at the DL Seeds Research Station in Morden, Manitoba during the 2020 and 2021 growing seasons. The trials were arranged in a RCB design consisting of 3 replications per variety. Plots consisted of 6 rows 4 metres in length with a row spacing of 17 cm and a planting density of 50 plants per square metre. Measured characteristics were based on 100 measurements of each variety per year. Mean differences were significant at the 5% probability level based on a Student's t-test.
