Origin & Breeding History: 'NQ19R' is a sister line to the variety 'NQ94PT' and was selected as a single plant from 'NQ94PT' in the spring of 2017 in Saskatoon, Saskatchewan. Over the next three generations, the line was increased and purified for plant type and seed color.

Tests & Trials: The comparative trials for 'NQ19R' were conducted in Elm Creek, Manitoba during the summers of 2020 and 2021. There were 3 replicates per variety arranged in an RCB design. Plots were 9 square metres and consisted of 6 rows measuring 6 metres in length with a row spacing of 23 centimetres. The seeding density resulted in at least 1700 plants per plot per variety per year. Measured characteristics were based on a 60 measurements per variety except seed weight with 21 measurements per variety. Mean differences were significant at the 5% probability level based on paired Student's T-tests.
