Roslinsky: Pod Shatter Resistant Canola
Researchers are using standard molecular biology protocols to generate a genetic framework map and to try to develop lines that include genetic control of pod shatter.

Fusarium wilt resistance in Brassica napus was found to be conferred by a single dominant gene, the A-genome. This means that B. rapa and B. oleracea may be sources of resistance to fusarium wilt available to B. napus breeders.
The development of early maturing canola is crucial to the northern canola growing areas of western Canada. Although B. rapa has several advantages over B. napus, producers currently have very few cultivars from which to choose, and only one with resistance to blackleg.
Flexibility in rotation planning allows canola and field pea producers to adapt to changing management practices and marketing opportunities. Current recommendations are to follow a one in four year rotation for canola or field pea on a particular field.
Technologies have been developed to control the extensive feeding that occurs in Canola (Brassica napus) due to the crucifer flea beetle.
Sclerotinia sclerotiorum is the causal agent of Sclerotinia stem rot (SSR), and can cause severe economic damage to Argentine canola. Researchers know that if it were available, genetic resistance to SSR would be an attractive option to canola growers.
Leptosphaeria maculans, the cause of blackleg, causes significant yield loss in canola crops. In this study, researchers compared pathogen survival and inoculum production of infested residues in both blackleg resistant cultivars and blackleg susceptible herbicide tolerant cultivars.
