Aurora Cannabis Inc. has announced a breakthrough in plant genetics with the discovery of PM2, a novel genetic resistance source against powdery mildew (PM) in cannabis sativa. This development is the result of Aurora’s deep investment in genetic research and is now integrated into its breeding program. The company plans to release cultivars with this resistance trait later this year, enhancing the plant’s resilience to one of the most persistent pathogens in cannabis cultivation. The proprietary marker technology tied to PM2 represents a significant advancement in disease-resistant breeding strategies.

The discovery is backed by peer-reviewed research conducted in collaboration with the University of British Columbia, led by Aurora’s Principal Scientist Jose Celedon. The study supports the premise that breeding for genetic resistance is a sustainable alternative to chemical treatments, particularly in regulated medical cannabis markets where synthetic pesticides are not viable. Aurora’s focus on strengthening biosecurity, reducing production costs, and improving quality places this development at the intersection of scientific innovation and commercial viability.

Aurora Coast, the company’s research and development facility, plays a key role in breeding innovation and advancing proprietary cultivars. Vice President Lana Culley emphasized that this achievement showcases Aurora’s leadership in research-driven cultivation and sets the company apart from competitors. The PM2 trait is expected to become a cornerstone in next-generation cultivars, allowing the company to scale production more effectively while maintaining high standards for product consistency and safety.

Powdery mildew is one of the most widespread and damaging pathogens affecting cannabis crops globally, often leading to major financial losses and compromised quality. By embedding genetic resistance at the cultivar level, Aurora not only addresses a top-tier cultivation challenge but also sets a new standard for sustainability in the industry. This breakthrough highlights the direction in which high-performing cannabis companies must move—toward biosecurity, innovation, and scalable, compliant cultivation practices.
