The next frontier for corn breeding in North America is the shorter season growing environments of Canada, specifically Manitoba, Saskatchewan, and parts of Ontario. Hybrids specifically developed for these environments are extremely limited, retarding the expansion of corn acreage in these regions. This proposal represents the collaborative efforts of the sole University corn breeder in Canada, the largest Canadian-owned seed corn company (Maizex Seeds Inc.), and DLF Pickseed which until recently was a Canadian-owned company specializing in forages and turf for Eastern and Western Canada. Collectively our aim is to develop inbred parents and hybrid combinations that are designed for the unique extremely short season environments of Manitoba, Ontario and the other Western Provinces. Beyond the development of inbred lines and hybrids, our research focuses on 3 key questions, which will greatly facilitate future breeding efforts. (1) What features of the environment and of the corn plant limit productivity and increase risk of crop failure? (2) What are the ideal characteristics of a successful corn hybrid in these extremely short season environments? (3) How are these ideal characteristics inherited? Finally, this highly collaborative proposal creates a unique opportunity for both undergrad and graduate students to acquire hands-on experience working side-by-side with commercial corn breeders and product managers.

北美玉米繁殖的下一个边界是加拿大较短的季节生长环境，特别是曼尼托巴省，萨斯喀彻温省和安大略省的部分地区。专门针对这些环境开发的杂种非常有限，在这些地区延伸了玉米面积的扩展。该提案代表了加拿大唯一的大学玉米饲养员的合作努力，加拿大是加拿大最大的种子玉米公司（Maizex Seeds Inc.）和DLF Pickseed，直到最近才是加拿大拥有的公司，专门为东方和西部和草皮提供的公司和草皮加拿大西部。 总的来说，我们的目标是开发近交父母和混合组合，这些组合是为曼尼托巴省，安大略省和其他西方省份独特的非常短的季节而设计的。 除了近交和杂种的发展之外，我们的研究还集中在3个关键问题上，这将极大地促进未来的繁殖工作。 （1）环境的哪些特征和玉米植物限制了生产力并增加农作物衰竭的风险？ （2）在这些非常短的季节环境中，成功的玉米混合动力车的理想特征是什么？ （3）这些理想特征如何继承？ 最后，这项高度协作的建议为本科和研究生提供了与商业玉米育种者和产品经理并排工作的独特机会。
