Canola clubroot disease: Winning the fight has never been closer

Date:07-12-2023

NRGene Canada, an AI genomics company, has reached a  major milestone in the development of new canola lines harboring high resistance against the devastating clubroot fungal disease.

NRGene Canada has now successfully mapped the unique genomic locations of a previously-identified novel high-resistance trait for clubroot disease in canola. DNA markers were also developed by the company to facilitate efficient trait integration into elite canola seeds. By growing resistant seeds, farmers can reduce yield loss by up to 90% in infected areas^[1]. This translates into potential savings of billions of dollars.

In addition, the company has developed DNA markers to enable the identification of clubroot resistance plants using simple PCR tests. NRGene’s Canola-SNPro™ genotyping kit, developed in 2021, allowed the DNA markers to be developed in just a few weeks. Since then, leading seed developers have used the kit for trait mapping and the development of new canola varieties. Canola seed producers can thus utilize the identified DNA markers to develop and commercialize novel disease-resistant canola seeds in a rapid and cost-efficient manner and provide farmers with an efficient and sustainable solution.

A provisional patent was recently filed by NRGene Canada to protect these high-resistance traits.

Canola is one of Canada’s most valuable crops, contributing over CAD$29.9 billion annually towards the Canadian economy^[2]. Unfortunately, clubroot has been expanding exponentially throughout the Canadian prairies since 2003. To date, no chemical treatment is available to eliminate clubroot from the soil, leaving farmers with fewer and less desirable options in their rotation schedule.

The disease affects the plant root structure and its ability to uptake nutrients, thus harming yield output. If left untreated, the significant decline in crop yields will severely impact global food security^[3].

This development has created a new defense strategy for Canadian farmers against this disease.

″NRGene’s activity in the heart of the Canadian Prairies for over 3 years is already paying off with the development of a natural and efficient solution to overcome this most devastating disease in canola and save local farmers billions of dollars from yield loss,″ said Dr. Gil Ronen, NRGene founder and CEO. ″We look forward to partner with leading seed producers and supply farmers novel, disease-resistant seeds.″

With the support of the Canada Industrial Research Assistance Program (IRAP), NRGene Canada expects to complete the project by 2025. The company is presently seeking Canadian and global partners to ensure that varieties bearing these resistance genes are available to farmers and producers.

″Innovation and AI-Genomics empower us to provide farmers with resilient Clubroot resistance in Canola, safeguarding both crop health and the environment. By deploying cutting-edge technologies, we are building a sustainable future for Canola before the next agricultural pandemic strikes. We recognize the importance of preparing for future challenges in crop security, driven by emerging pathogens. It’s not a question of if, but rather when.″ said Dr, Masood Rizvi, General Manager, NRGene Canada
