Leading Genetics in Canola

Our Strategic Canola Breeding Partner

With their extensive testing network and local expertise in disease resistance, DL Seeds is delivering solutions that are profitable for North American growers. DL Seeds is our canola breeding partner and the source of our high-performance, industry-leading varieties BY 6207TF and BY 5125CL and proven performers like 6074 RR and 6090 RR. DL Seeds, along with its Germany-based parent companies, DSV and NPZ Lembke, is truly a global oilseed breeding powerhouse, with more than 15 oilseed and canola breeders operating in North America, Europe and Australia. The breeding program has unrivalled access to diverse germplasm that year after year produces industry-leading canola varieties. DL Seeds brings this worldwide technology to farmers by utilizing a large trial network dedicated to testing top-performing canola hybrids for the North American market.

FIRST-CHOICE ACCESS

Access to first-tier genetics and traits from a breeding program is important. That's why BrettYoung receives preferential, first-choice access to the top hybrids across all canola herbicide tolerance segments produced by DL Seeds’ canola breeding program. This allows us to deliver the bottom-line impact that farmers are looking for.

Outstanding Genetic Resistance to Pod Shattering

BrettYoung’s DefendR platform was developed to highlight the superior disease resistance genetics developed by our strategic canola breeding partner, DL Seeds Our nextgeneration clubroot-resistant hybrids are industry-leading and our strong R, multi-genic blackleg resistance packages have been a key aspect of many DefendR-rated products

Pod DefendR Shatter Resistance – Flexibility and Peace of Mind

The introduction of pod shatter-resistant hybrids to canola growers several years ago led to a significant increase in adoption of both direct harvesting and delayed swathing of canola crops BrettYoung canola growers can now enjoy this same flexibility because of our new pod shatterresistance trait, which is non-GMO and delivers dependable levels of shattering tolerance

Physiology of Pod Shatter

Pod shattering and the seed dispersion associated with it is a survival mechanism found in nature Yet, despite decades of breeding and domestication, canola pods still have a natural tendency to split and open at maturity, with the goal of scattering seeds Breeders and researchers, however, have been working to understand the physiology of pod maturation and pod shatter mechanisms Some canola breeding programs have been able to identify hybrids with higher levels of natural pod shatter resistance through screening and selection However, this approach has had limited effectiveness relative to the levels of pod shatter resistance achieved with a true genetic trait

DL Seeds and its parent companies have been researching other solutions, and what has emerged is an understanding of a complex pathway of gene interaction that controls pod valve function (see figure) Much of the work has meant isolating specific genes from other Brassica species and breeding them into canola to interrupt these shatter-inducing pathways; mustard growers are well aware of the substantial shatter resistance a similar mechanism provides The result is Pod DefendR, a specific genetic trait that reduces tensions built up at maturity and, ultimately, the tendency for pods to split at the pod dehiscence zone (or pod seam) that holds both sides of the pod (valves) together

Testing

Canola hybrids with the Pod DefendR trait are evaluated in both lab and field, and over different protocols to ensure the presence of the trait and that the reduction of shattering in the hybrid is stable, consistent and effective Visit brettyoung.com to learn more about the canola hybrids that feature this exciting new trait
