Narrative
Clearwater plants flowered on average 58.8 days after planting, which is not significantly different from Sunrise. Clearwater plants are significantly taller (127.8 cm) than Sunrise (118.9 cm). Clearwater plants reached full maturity on average 97 days after planting, which was not significantly different from Sunrise. Average 1000-seed weight of Clearwater is 3.4 g, similar to Sunrise at 3.3 g. Clearwater was grown in replicated yield trials alongside Sunrise and Hyola.401 at a total of 79 year-sites between 2001 and 2007. None of these yield evaluation trials had imazamox herbicide applied. Average over all years and sites, Clearwater seed yield was 1,748 kg ha-1 compared to 1,646 ka ha-1 for Sunrise and 1,986 ka ha-1 for Hyola Clearwater also was grown in yield trials at two locations in 2004 and 2005 where seedlings in the trials were sprayed with 0X, 2X (70 g a.i. ha-1), and 3X rates (equivalent to 105 g a.i. ha -1) rates of imazamox herbicide at the 4-5 leaf stage. Average over year s and sites, seed yield of Clearwater was almost identical with 0X herbicide rate (1,748 kg ha-1) compared to 2X herbicide rate (1,730 kg ha-1). Average oil content of Clearwater is 391 g kg-1. Seed oil fatty acid composition of Clearwater was very similar to Sunrise, where the primary fat was oleic acid. Clearwater seed oil consistently contained less than 3 g kg-1 euric acid, less than 80 g kg-1 linolenic acid and more than 620 g kg-1 oleic acid. Total glucosinolate content of Clearwater seed meal was 9.1 ?mol g-1 of defatted seed meal. Primary glucosinolate was 2-hyroxy-3-butenyl (average 3.7 ?mol g-1) followed by 3-butenyl (average 2.9 ?mol g-1).

Pedigree
Description:
Clearwater is a near pure-line spring canola cultivar which as high resistance to imidazolinone class herbicides including imazamox. Clearwater was developed from the cross `CFSN.39.9?/`Sunrise?///?Sunrise?. CFSN.39.9 is a breeding line that was selected from a segregating F3 population from a cross `Profit?/`Springfield?, where progeny were accidentally planted into soil with a high imazamox residue. Sunrise is a canola-quality spring rapeseed cultivar developed and released by the University of Idaho in 1997 (Brown et al. 1997 Crop Sci. 38:542-543)
