Description:
PLANT: open pollinated, allotetraploid, short to medium height at flowering, flowers late in the season
LEAF: wide elliptic shape, medium green, few lobes, rounded to sharp margin, shallow to medium dentations of margin
FLOWER STALK: high degree of branching
PETALS: yellow
SILIQUE: medium width, short to medium length, short beak, short pedicel
SEED: medium number per silique, medium sized, yellow
AGRONOMIC CHARACTERISTICS: fair to good resistance to lodging
Origin & Breeding History: 'DH146842' originated from a cross between a selection from the Australian Temperate Crop collection, Accession 93972, designated AU041-11J, and a Nuseed line designated DH001.080. The cross was conducted in December 2013 and each resulting F1 plant was used for the development of a family of double haploid lines. In 2015-2016, seed from the double haploid lines were grown in rows in Temuco, Chile where one line, designated 'DH146842', was selected based on agronomic properties and seed quality.
Tests & Trials: The comparative trials for 'DH146842' were grown during the summers of 2018 and 2019 at a Mustard (B.carinata) breeding nursery, in Outlook, Saskatchewan. Plots were arranged in a RCB design with 4 replicates per variety each year. Each 6.0 by 1.5 metre plot had a seeding density of 100 seeds per metre squared. Each plot consisted of 5 rows with 0.31 metre spacing between rows. The measured characteristics were based on a minimum of 30 measurements per variety, except cotyledon width in 2019, which was based on a minimum of 24 measurements. Mean differences were significant at the 5% probability level based on a Student`s t-test.
