Canola is a high value export crop from Australia, and an important rotational crop which improves sustainability of agriculture through a disease and weed break for cereal crops. While breeders have improved quality, disease resistance and adaptation of canola to Australian conditions over the past 30 years, this has reduced genetic variation to dangerously low levels. Wide crossing with drought tolerant Brassica carinata (Ethiopean mustard) will help to alleviate this problem. New uses of biotechnology, combined with molecular genetics, will help to overcome species barriers to introduce useful new genes into canola for Australian canola breeders.

油菜籽是澳大利亚的一种高附加值出口作物，也是一种重要的轮作作物，通过谷类作物的病害和杂草破坏来提高农业的可持续性。尽管在过去的30年里，育种者提高了油菜籽的质量、抗病能力和对澳大利亚条件的适应能力，但这将遗传变异减少到了危险的低水平。与耐旱的隆起甘蓝(埃塞俄比亚芥菜)远缘杂交将有助于缓解这一问题。生物技术的新用途，结合分子遗传学，将有助于克服物种障碍，为澳大利亚油菜育种者将有用的新基因引入油菜籽。
