Variety Description

Variety used for comparison: 'S16-F5'

Summary: The colour of the hairs on the middle third of the main stem of 'S14-H3' are light tawny while they are grey for 'S16-F5'. When 95 % of the pods are ripe, the plants of 'S14-H3' are taller than those of 'S16-F5'. The 100 seed weight of 'S14-H3' is less than that of 'S16-F5'. The plants of 'S14-H3' are earlier maturing than those of 'S16-F5'.

STEM: light tawny pubescence on middle third

LATERAL LEAFLET: pointed ovate shape

FLOWER: violet

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

Origin & Breeding History: 'S14-H3' (experimental designation AR1102956) originated from the cross 10806/85436 conducted in 2009 in Arva, Ontario. The F1 and F2 generations were grown in a winter nursery in Kekaha, Hawaii in 2009-2010. The F3 generation was grown in Hawaii in 2010. In the winter of 2010/2011, single plants were selected from the F4 generation, with the F5 generation being grown out in single row yield trials at Arva, Ontario during the 2011 growing season. One of these lines, identified as AR1102956, was selected for further testing based on superior agronomic characteristics. In 2012, a progeny row increase was planted and carefully rogued for off-types, harvested individually and bulked after each individual row was observed. AR1102956 was evaluated in wide area testing during the 2013 to 2014 growing seasons. Selection criteria included yield performance, disease resistances and quality characteristics.

Tests & Trials: The comparative trials for 'S14-H3' were conducted at Syngenta Canada, Inc., Arva, Ontario during the 2015 and 2016 growing seasons. The plots consisted of 3 replications per variety containing 4 rows per replicate with a row length of 5 metres and a row spacing of 0.8 metres. Each plot was sown with approximately 500 seeds. For each trial year, the measured characteristics were based on 20 height measurements per variety, and 10 seed weight measurements per variety. Means are based on a two year average. Mean differences were significant at the 5% probability level based on a paired Student t-test.
