High-yielding, superior quality, disease-resistant, herbicide-tolerant hybrid high erucic acid rapeseed research at the University of Manitoba

2007-2009年期间，加拿大油菜/油菜籽产业每年为加拿大经济贡献154亿美元。高芥酸油菜籽（HEAR）生产是加拿大菜籽/油菜籽产业的一个小而有利可图的组成部分，加拿大每年生产的芥酸油约占全球供应量的一半。芥酸油及其衍生物用于润滑剂、防滑剂、塑料、油漆、涂料、化妆品、尼龙和药品。目前开放授粉的HEAR品种产量约为2200公斤/公顷，而目前的杂交油菜品种产量约为2500公斤/公顷。在加拿大，由于小麦和油菜籽品种在同一生产区域竞争，发展小麦杂交品种对于维持小麦生产的盈利是必要的。拟议的HEAR合作研究与开发项目侧重于在马尼托巴大学开发高产、优质、抗病、耐除草剂（HT）的HEAR杂交品种。我们将通过两种不同的授粉控制系统、增加甘蓝型油菜多样性的产生、利用标记辅助选择、进一步表征加拿大西部黑腿病变异和黑腿抗性遗传来实现这一目标。该项目将整合马尼托巴大学（dr . Manitoba）在植物育种、基因组学和抗病方面的专业知识。Duncan， Fernando和Li)， DL Seeds在育种和杂交开发方面的专业知识以及加拿大Bunge的种子/油/粉加工传统。我们的团队将生产出世界上第一个杂交HT HEAR品种，在短期内，杂交HT HEAR研究和开发将使HT HEAR产量至少提高10%至15%。这种独特而有利可图的作物的杂交产量优势将为加拿大经济增加显著的年度价值，使农民、种业和种子加工商受益。该研究将为培养植物育种、植物基因组学和植物病理学方面的高素质人才提供一个独特的教育场所。这些地区对卫生服务人员的需求很大，而且在稳步增长，而培训这类卫生服务人员的能力却在下降。

The Canadian canola/rapeseed industry contributed $15.4 billion annually to Canada's economy in the 2007-2009 period. High Erucic Acid Rapeseed (HEAR) production is a small but profitable component of the Canadian canola/rapeseed industry, with Canada producing approximately half of the annual global supply of erucic acid oil. Erucic acid oil and its derivatives are used in lubricants, slip agents, plastics, lacquers, coatings, cosmetics, nylons and pharmaceuticals. Current open pollinated HEAR cultivars yield approximately 2200 kg/ha, while current hybrid canola cultivars yield approximately 2500 kg/ha. Developing HEAR hybrids is necessary to maintain profitable HEAR production in Canada, since HEAR and canola cultivars compete for the same production area. The proposed HEAR Collaborative Research and Development Project focuses on the development of high-yielding, superior quality, disease-resistant, herbicide-tolerant (HT) hybrid HEAR cultivars at the University of Manitoba. We will accomplish this using two different pollination control systems, generation of increased Brassica napus diversity, utilization of marker-assisted selection and further characterization of blackleg disease variation in western Canada and the genetics of blackleg resistance. This project will incorporate expertise in plant breeding, genomics, and disease resistance at the University of Manitoba (Drs. Duncan, Fernando and Li), expertise in breeding and hybrid development from DL Seeds and a tradition of seed/oil/meal processing from Bunge Canada. Our team will produce the world's first hybrid HT HEAR cultivar, and in the short-term, hybrid HT HEAR research and development will increase HT HEAR yields by at least 10 to 15%. The hybrid yield advantage of this unique and profitable crop will add significant annual value to the Canadian economy, benefiting farmers, the seed industry and seed processors. This research will provide a unique educational venue for training highly qualified personnel (HQP) in plant breeding, plant genomics and plant pathology. The demand for HQP in these areas is large and growing steadily, while the capacity to train such HQP is declining.
