Origin & Breeding History: In 2008, a population of plants from private and public collections were grown in Salem, Oregon, USA. Within the populations, 6 plants survived and were subsequently planted in an isolated crossing block. Each plant was harvested and the seed was kept separately. In the winters of 2010 and 2011, all lines were evaluated for cold hardiness in Birmingham, Iowa. Seed from a line designated as 'GO-8-72-4' was identified as the only line that exhibited no cold damage. Progeny of 'GO-8-72-4' was subjected to 3 cycles of recurrent selection and further evaluated for 4 years. 'GO-BER-10' was selected in 2012 based on dry matter yield, crude protein content, and plant vigour and was further propagated by seed.

Tests & Trials: The comparative trials for 'GO-BER-10' were conducted in Chilliwack, British Columbia during multiple growing seasons in 2020 and 2022. Trials were conducted in field plots and potted trials. All trials were arranged in a RCB design with 3 replicates. Field and potted plants were sown, maintained using drip irrigation and placed in rows measuring 5 metres in length and spaced 0.5 metres apart. Potted containers were thinned to 3 plants per 1 gallon pot. A minimum of 60 to 180 plants per variety were included in each trial year. Observations and measured characteristics reported from the potted trials were based on 60 plants or 60 parts of plants. Mean differences were significant at the 5% probability level based on Student's t-tests.
