Pink Pepper Is the New Rosetta Stone of Cannabis

Pink Pepper, a visually arresting cannabis variety with rich magenta tones, is turning heads for more than its aesthetic. In early 2025, scientists at Colorado State University Pueblo’s Institute of Cannabis Research (ICR), in collaboration with Kangwon National University in South Korea, unveiled a nearly gapless genomic map of the cultivar—now the most complete Cannabis sativa genome on record.

Clocking in at 99.6% completeness with over 30,000 annotated protein-coding genes, the Pink Pepper genome has become the new reference standard, officially recognized by the National Center for Biotechnology Information. It replaces the patchy and inconsistent assemblies that have held cannabis research back for years.

According to researchers at Kangwon National University, the Pink Pepper genome “serves as a valuable resource for advancing genetic research on hemp,” providing “more precise fundamental information for not only cannabis breeding but also studies on the biological characteristics” of the plant.

A Clean Blueprint at Last

Cannabis genome sequencing has had a long history of false starts. The first widely recognized map, published in 2011 from the Purple Kush strain, left large gaps and unresolved scaffolds. Others followed, but none provided the level of resolution needed to support large-scale breeding or pharmaceutical development.

The team behind Pink Pepper solved this by integrating three advanced sequencing methods: PacBio SMRT for structural depth, Oxford Nanopore for long reads, and Illumina for high-accuracy polishing. The final product consists of just 17 chromosomal scaffolds, a sharp contrast to the thousands found in earlier assemblies.

“Such assemblies create confusion for data users in distinguishing between real genome differences and assembly errors,” noted the Kangwon team in their study. “Our assembly demonstrated the highest complete BUSCO scores among the reported cannabis genomes.”

This is undoubtedly a huge win for computational biology, offering a foundational tool for applied science. High-continuity genomic maps allow researchers to track gene expression with unprecedented accuracy, enabling studies on how cannabis interacts with environmental stressors, pathogens, and nutrients. With this level of resolution, it’s possible to anticipate how different growing conditions might influence cannabinoid production.

Data With Direction

Pink Pepper is a Type III cannabis cultivar bred for high CBD and minimal THC. The breeding process, which drew on genetics from 26 hemp varieties, was designed for therapeutic consistency. Its bold color—ranging from hot pink to deep plum—was an unexpected byproduct.

The genome includes detailed annotations of the genes responsible for synthesizing cannabinoids like CBD and THC, as well as terpene pathways that influence aroma and therapeutic effects. Kangwon researchers note that the assembly allows “understanding the cannabinoid and terpene biosynthesis mechanisms in cannabis [that] could ultimately contribute to the development and application of medical cannabis.”

For those interested in the plant’s pharmacological value, this data could be transformative. Identifying key regulatory genes for CBDA synthase and THCA synthase lays the groundwork for biotechnological interventions—whether that’s enhancing therapeutic potency, reducing unwanted compounds, or even developing new formulations altogether.

Setting the Bar

With its BUSCO score—the gold standard for genome completeness—leading the field across all three plant databases tested, Pink Pepper has redefined what’s possible in cannabis genetics. It gives labs across the globe a common, verified dataset to build on.

Breeders now have a foundation to develop cultivars with greater consistency in yield, cannabinoid expression, and resilience. For pharmaceutical developers, Pink Pepper’s map accelerates the path to targeted formulations. Even regulators and testing labs stand to benefit from a clearer genomic picture.

The researchers also conducted synteny comparisons with related species like Humulus lupulus (hops), revealing strong genetic parallels that could influence both evolutionary biology and cross-species insights. This kind of work not only deepens understanding of cannabis itself but also broadens its relevance across plant science.

Cultivar Meets Commerce

ICR and its Korean research partners are launching Pink Pepper Biotech, a genetics company that will steward commercial licensing. Seeds will initially be released to certified institutions and industrial stakeholders, with revenue funneled back into research.

According to the ICR press release, “Seeds of Pink Pepper will eventually be available for scientific research and industrial cannabinoid production.”

The genomic data, however, is open-source and already in use. Scientists can access the full genome via NCBI or through linked datasets at Figshare, allowing public and private researchers alike to explore its potential. With this level of transparency, the Pink Pepper project is poised to accelerate not just proprietary development, but the public good.

A Global Reference Point

Already, Pink Pepper’s data is being used in projects from Europe to South America. For countries navigating complex cannabis laws, having a CBD-rich, genetically stable cultivar backed by public science offers an accessible starting point.

In South Korea, where medical cannabis research remains tightly regulated, the Pink Pepper project has opened new academic and commercial avenues for genomic research under strict oversight. In the U.S., it’s reinforcing the role of land-grant institutions like CSU Pueblo in advancing agricultural biotechnology.

Back at CSU Pueblo, students in the university’s cannabis science program are learning genomics using Pink Pepper, becoming part of the curriculum. “This genome is a teaching tool, a research engine, and a launchpad for innovation,” Park shared in internal university communications.

Toward a Standardized Future

The cannabis industry has long been shaped by folklore and intuition. Pink Pepper injects hard data into the mix. It clarifies, verifies, and simplifies the work of everyone from plant scientists to policymakers.

Its significance can’t be overstated. It’s a genomic scaffold that could support generations of research, cultivation, and product innovation.

In a space that often over-promises, Pink Pepper delivers the infrastructure needed to move from anecdote to analysis, from guesswork to genomics.
