Advancing High Erucic Acid Rapeseed Research and Development in Canada

加拿大油菜/油菜籽产业每年为加拿大经济贡献267亿美元。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和滑脱剂，芥酸具有石油基产品所不具备的特性。目前的杂交HEAR品种是基于授粉控制系统，在加拿大西部生产大量商业杂交种子时可能会带来挑战和不一致。开发具有Ogu INRA授粉控制系统的HEAR杂交种对于保持加拿大HEAR的盈利生产是必要的，因为HEAR和油菜品种在同一生产区域竞争。拟议的HEAR合作研究与开发项目侧重于使用Ogu INRA授粉控制系统开发HEAR杂交品种，并使用新的耐除草剂系统（TruFlex）对这些杂交种进行转化。我们将通过将来自行业合作伙伴的改良的Ogu INRA亲本与马尼托巴大学先前开发的HEAR种质相结合来实现这一目标。在总体研究目标中，除了基因编辑之外，我们将有多个目标，重点是利用常规育种方法提高种子质量，提高非生物胁迫和抗病性。这项研究将结合植物育种、遗传学、基因组学、抗病性和植物生理学方面的专业知识。Duncan, Li， Stasolla和Hill)， Nutrien的杂交开发专业知识和Bunge的种子/油/粉加工传统。我们的团队将生产世界上第一个TruFlex HEAR混合动力车。使用Ogu INRA授粉控制系统和新的除草剂耐受性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。这项创新研究还将为培养植物育种、植物基因组学和植物生理学方面的高素质人才提供一个独特的综合教育场所。

The Canadian canola/rapeseed industry contributes $26.7 billion annually to Canada's economy. 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 and slip agents and erucic acid offers properties that petroleum-based products do not. Current hybrid HEAR cultivars are based upon a pollination control system that can pose challenges and inconsistencies when producing large amounts of commercial hybrid seed for western Canada. Developing HEAR hybrids with the Ogu INRA pollination control system 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 hybrid HEAR cultivars using the Ogu INRA pollination control system and the conversion of these hybrids using a new herbicide tolerance system (TruFlex). We will accomplish this by combining improved Ogu INRA parents from our industry partners with the previously developed HEAR germplasm from the University of Manitoba. Within the overall research goal, we will have multiple objectives focusing on the improvement of seed quality, abiotic stress and disease resistance using conventional breeding approaches in addition to gene-editing. This research will incorporate expertise in plant breeding, genetics, genomics, disease resistance and plant physiology at the UofM (Drs. Duncan, Li, Stasolla and Hill), expertise in hybrid development from Nutrien and a tradition of seed/oil/meal processing from Bunge. Our team will produce the world's first TruFlex HEAR hybrid. The use of the Ogu INRA pollination control system and new herbicide tolerance will add significant annual value to the Canadian economy, benefiting farmers, the seed industry and seed processors. This innovative research will also provide a unique, integrated educational venue for training highly qualified personnel (HQP) in plant breeding, plant genomics and plant physiology.
