Description:

PLANT: very early to early flowering, medium green foliage

LEAFLET: maximum width located at middle

Origin & Breeding History: '186s-11' originated from a cross conducted in 2004 at the Crop Development Centre of the University of Saskatchewan in Saskatoon, Saskatchewan. The cross was made between the varieties 'Reina Blanca' and 'Puebla'. '186s-11' was selected from an F8 sub-line derived from a single plant. Selection of '186s-11' was based on yield, seed weight, seed size, seed coat colour, days to flowering, days to maturity, lodging and plant height.

Tests & Trials: The comparative trials for '186s-11' were conducted during the summer of 2014 and 2015 at the Preston field site of the University of Saskatchewan in Saskatoon, Saskatchewan. The trials consisted of two replications in a RCB design. Planting density was 40 seeds per metre square, planted in three rows. The rows were 3.66 metres long with a row spacing of 0.30 metres. The observations and measurements were taken randomly from 60 plants of each variety.
