Origin & Breeding History: 'H92004-1' was developed from the cross between the varieties 'Purplediol CBD' and 'Katani' conducted at LaSalle, Manitoba by Haplotech Inc. (acquired by Farmers Business Network Canada) in the spring of 2019. The cross was followed by two generations of full-sib mating with negative selection for maturity, CBD content, and CBD to THC ratio. One hundred seeds were harvested from each of three selected full sib families and bulked to form breeder seed in 2020.

Tests & Trials: The comparative trials of 'H92004-1' were conducted during the 2022 and 2023 growing seasons in Carman, Manitoba. The trials consisted of four replicates in a randomised complete block design with each replicate consisting of 6 rows approximately 6.6 metres long. Each plot was 10 metres squared with a seeding density of 40 seeds per square metre resulting in approximately 1600 plants per variety per year. The measurements were taken from 20 plants, or parts of 20 plants, of each variety. Mean differences were significant at the 5% confidence probability level based on a paired Student's t-test.
