Variety Description

Varieties used for comparison: 'AC Parkland' and 'Tobin'

Summary: 'ACS-C16' has longer pedicels than both reference varieties, 'AC Parkland' and 'Tobin'. The leaves of 'ACS-C16' are not as lobed as they are in 'AC Parkland'. The plants of 'ACS-C16' are taller than those of 'Tobin'.


'ACS-C16' is an open-pollinated spring Polish canola population. The cotyledons are narrow. The leaves are light green with few to a medium number of leaf lobes. The leaf margins are rounded with very shallow to shallow dentation. The flowers of 'ACS-C16' are yellow. The silique is very short, the beak is long to very long and the pedicel is short to medium in length. Plants are short and seed colour is mixed yellow-brown. 'ACS-C16' has low glucosinolate and erucic acid levels. It is susceptible to Alternaria black spot (Alternaria brassicae and Alternaria raphani), susceptible to Blackleg (Leptosphaeria maculans), highly susceptible to Sclerotinia stem rot (Sclerotinia sclerotiorum) and moderately resistant to white rust (Albugo candida race 7a).

Origin & Breeding History: 'ACS-C16' was derived through natural sexual crosses between 'Tobin' and a strain closely related to the variety, 'Horizon'. The initial cross was made in 1985. The F2 seed was sown in a composite crossing block in Melfort, Saskatchewan in 1993. Following three years of recurrent selection, an equal bulk of 500 seeds from 23 individual plants were screened for low erucic acid content using the half-seed method. 'ACS-C16' was selected based on plant vigour, seed oil and meal protein contents, and low glucosinolate content.

Tests & Trials: Tests and trials for 'ACS-C16' were conducted at the Elora Research Station, Elora, Ontario during the summers of 2000 and 2002. Trials consisted of 4 rows per plot, 2 replicates per entry with each replicate 1.5 metres wide by 5 metres long.
