| Six ogu INRA CMS canola hybrids, their parents and three open pollinated check cultivars were grown in replicated yield trials at 6 locations in 2006 and 4 locations in 2008 and assessed for seedling vigour, plot uniformity, days to 50% flower, days to maturity, plant height, oil content, protein content, sum of oil and protein content, glucosinolate content and saturated fatty acid content. The hybrids displayed mid-parent heterosis for seedling vigour, uniformity, days to 50% flower, days to maturity, plant height, seed oil content, sum of oil and protein content and glucosinolate content. The hybrids also displayed high-parent heterosis for seedling vigour, uniformity, plant height, seed oil content and glucosinolate content. Heterosis for seed oil content was frequently observed and suggests that it may be possible to develop high seed yield, high oil content B. napus hybrids to grow in western Canada. |
