Variety Description

Variety used for comparison: 'S20-G7'

Summary: When 95% of the pods are ripe, the plants of 'S20-M1' are shorter than those of 'S20-G7'. 'S20-M1' has a light brown pod whereas it is dark brown for 'S20-G7'. At maturity, the 100 seed weight for 'S20-M1' is less than the 100 seed weight for 'S20-G7'.


PLANT: oilseed type, indeterminate growth type, semi-erect growth habit, grey pubescence on middle third of main stem, begins flowering mid-season, matures mid to late season

HYPOCOTYL: medium anthocyanin colouration

LEAF: pointed ovate lateral leaflet

FLOWER: violet

POD: light brown
SEED: spherical, yellow ground colour of testa
HILUM: yellow

Origin & Breeding History: 'S20-M1' (experimental designations AR1502197 and XC2087) originated from the cross between 12ALL000045 and 12ALL000149 conducted in 2012 in Arva, Ontario. The resulting seed was increased in a contra season nursery in Graneros, Chile in 2012-2013. Using the single seed descent method, the F2-F3 generations were also grown in Arica, Chile. Single F4 plants were selected in Graneros, Chile in the winter of 2013-2014. The resulting F5 generation was evaluated in a single replication trial in Arva, Ontario in 2014. The F6 and F7 generations were further evaluated in multiple trial locations in Canada and the United States from 2015 to 2017. A bulk increase of 'S20-M1' occurred at the F9 generation in Chillan, Chile in the winter of 2017-2018. Selection criteria included hilum colour, protein content and yield.

Tests & Trials: The comparative trials for 'S20-M1' were conducted at Syngenta Canada, Inc., Arva, Ontario during the 2018 and 2019 growing seasons. The plots consisted of 2 replicates per variety containing 2 rows per replicate with a row length of 5 metres and a row spacing of 0.75 metres. The plant height was based on 20 measurements per variety per year whereas the seed weight was based on 10 measurements per variety per year. Mean differences were significant at the 5% probability level based on LSD values.
