Apples are one of the most important fruit crops in Ontario with nearly 16 000 acres in production worth over $87 000 000/year. Apples are typically propagated by grafting onto specific root stocks to maintain desired characteristics and the rootstock must be asexually propagated to maintain these traits. Ontario growers currently obtain rootstock from American, European, and some Canadian producers. The dependence on foreign sources introduces the potential for introduction/spread of insects and disease and supply could be delayed or interrupted at any given time. A domestic supply of rootstock would reduce the chance of pest/disease introductions, ensure a continuous supply, and create jobs in Ontario.

苹果是安大略省最重要的水果作物之一，种植面积近16000英亩，年产值超过8700万美元。苹果通常是通过嫁接到特定的砧木上来繁殖，以保持所需的特性，而砧木必须无性繁殖才能保持这些特性。安大略省的种植者目前从美国、欧洲和一些加拿大生产商那里获得砧木。对外国来源的依赖带来了引进/传播昆虫和疾病的可能性，供应在任何特定时间都可能延迟或中断。在国内供应砧木将减少病虫害传入的机会，确保持续供应，并在安大略省创造就业机会。
