Narrative
Gem plants flowered on average 57.4 days after planting, which is not different from Sterling (57.4 days after planting). Gem plants were on average 117.6 cm tall, which was not significantly taller than Sterling (115.3 cm). Gem plants reached full maturity on average 94 days after planting, which was not significantly different from Sterling which reaches maturity, on average 96 after planting. Average 1000-seed weight was 3.1 g, similar to Sterling at 3.0g. Gem was grown in replicated yield trials alongside Sterling and Hero at a total of 79 year-sites between 2001 and 2007. None of these yield evaluation trials had imazamox herbicide applied. Average overall years and sites, Gem seed yield was 1,650 kgha-1, which was not significantly higher than Sterling (1,625 ka ha-1) but significantly higher yield than Hero (1,494 ka ha-1) Gem was tested 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 (105 g a.i. ha -1) of imazamox herbicide at the 4-5 leaf stage. Average over year s and sites, seed yield of Gem was identical with 0X herbicide rate (1,762 kg ha-1) compared to 2X herbicide rate (1,731 kg ha-1), and only slightly reduced yield at the 3X herbicide rate (1,640 kg ha-1). Average seed oil content of Gem is 404 g kg-1. The primary oil in Gem is erucic acid, accounting for 463 g kg-1, which is significantly higher erucic acid content compared to Sterling. Total glucosinolate content of Gem seed meal was low (12.4 ?mol g-1 of defatted seed meal).

Pedigree
Description:
Gem is a near pure-line spring rapeseed cultivar which as high resistance to imidazolinone class herbicides including imazamox. This cultivar was developed from the cross `CFSN.39.9?/`Sterling?///?Sterling?. CFSN.39.9 is a canola-quality line that was selected from a F3 population from a cross `Profit?/`Springfield?, after progeny from the cross where accidentally planted into soil with a high imazamox residue. Sterling 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)
