Variety Description

Varieties used for comparison: 'Arid', 'Dahinda', 'Estlin' and 'Xceed 8571'

Summary: 'Oasis CL' has fewer leaf lobes than 'Arid' and 'Xceed 8571'. The dentations on the margin of the leaf of 'Oasis CL' are shallow while they are medium depth for 'Arid', 'Estlin' and 'Xceed 8571'. 'Oasis CL' flowers earlier than 'Arid' and 'Estlin'. The flower petal of 'Oasis CL' is larger than the reference varieties. 'Oasis CL' has a shorter silique than 'Estlin' and narrower than 'Dahinda'. The beak of 'Oasis CL' is shorter than 'Arid'. 'Oasis CL' has a longer pedicel than 'Arid', 'Dahinda' and 'Xceed 8571'. 'Oasis CL' is resistant to clearfield herbicides while 'Arid', 'Dahinda' and 'Estlin' are not.

Description:

QUALITY CHARACTERISTICS: erucic acid is 0.15% of total fatty acids, medium glucosinolates (15.56 µmol/g)

Origin & Breeding History: 'Oasis CL' (experimental designation J05Z-8920) was derived from a cross that occurred in 2004. An F1 plant from the cross was used as a donor plant to produce microspore derived doubled haploids in 2005. One doubled haploid line was selected during tissue culture based on Imi resistance. The line was developed using nurseries in Saskatchewan and Chile. Selection criteria included resistance to Imi herbicides, maturity, lodging resistance, yield, disease resistance and seed quality characteristics. It was entered into yield trials in Canada during the years from 2006-2008.

Tests & Trials: Trials were conducted during the summers of 2010 and 2011 in Watrous, Saskatchewan. Plots consisted of 6 rows with a row length of 5.5 meters and a row spacing of 20cm. There were 3 replicates arranged in a RCB design. There were 30 measurements each year for leaf, flower and plant height characteristics and 60 for the silique characteristics. Means are based on a two year average. Differences are significant at the 2% probability level based on LSD values.
