At GTR Seeds, progress has always started with science. From the very beginning of our modern hemp breeding efforts, our work has been guided by applied genetics, plant pathology, and agronomic research designed to address real-world challenges faced by farmers and the cannabis industry as a whole.
Over the years, this approach has led to several meaningful breakthroughs. Our team has been at the forefront of stabilizing cannabinoid expression, advancing polyploid and triploid plant development, exploring novel cannabinoid pathways, and releasing elite cultivars bred for reliability, field performance, and regulatory compliance. These innovations have helped transform cannabis from an inconsistent, high-risk crop into a more predictable agricultural system built on data, repeatability, and trust.
Our scientific commitment extends well beyond internal R&D. Members of our team have co-authored 11 peer-reviewed scientific publications, contributing directly to the broader understanding of cannabis genetics, disease resistance, and cultivation. Notably, this body of work includes a paper published in Nature, one of the most respected and influential scientific journals in the world.

This body of published research places us among a very small group of cannabis breeders actively contributing to peer-reviewed science. It reflects our belief that the long-term success of hemp and cannabis depends on transparency, reproducibility, and openly shared knowledge. As the industry continues to evolve, we remain committed to advancing the science and raising the bar for what modern cannabis breeding can achieve.
