Variety Description

Variety used for comparison: 'S14-H3'

Summary: When 95% of the pods are ripe, the pubescence on the middle third of the stem of 'S12-J7' is grey whereas it is light tawny for 'S14-H3'. The plants of 'S12-J7' are taller and earlier maturing than those of 'S14-H3'. At maturity, the 100 seed weight for 'S12-J7' is less than the 100 seed weight for 'S14-H3'.


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

HYPOCOTYL: medium anthocyanin colouration

LEAF: pointed ovate lateral leaflet

FLOWER: violet

SEED: spherical, yellow ground colour of testa
HILUM: yellow

Origin & Breeding History: 'S12-J7' (experimental designation EE1600331) originated from the cross between 12DL000130 and 12D000122 conducted in the winter of 2013 in a contra season nursery in Graneros, Chile. Using a single seed descent method, the F2-F3 generations were grown in Arica, Chile. Single F4 plants were selected for yield using plant appearance in the summer of 2014 in Owatonna, Minnesota, USA and the resulting F5 generation was evaluated in a single replication trial in 2015. The F6 and F7 generations were further evaluated in multiple trial locations in Canada and the United States in 2016 and 2017. A bulk increase of 'S12-J7' occurred at the F8 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 'S12-J7' 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.
