Cannabis Variety Breeding for Stable 1:1 THC-THCV Profiles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new and distinct Cannabis varieties with specific cannabinoid and terpene profiles for medicinal use, particularly for products with unique chemical characteristics suitable for extracts and isolates, which existing technologies have not adequately addressed.
Innovation Solution
The development of a new Cannabis variety, designated 'ESB-1', which is a sexual cross of 'P6-69' and 'P6-B1', exhibiting a THC:THCV ratio of about 1:1, purple leaf stem, and stable chemotypic characteristics, suitable for asexual propagation and breeding programs, with cannabinoid and terpene profiles within specific ranges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a new Cannabis variety with specific cannabinoid profile (THC:THCV ratio of 1:1) is developed through sexual cross, then the chemical characteristics suitable for medicinal use are improved, but the complexity of breeding programs and propagation stability requirements increase
Solution Approach 1:
The patent applies preliminary action by conducting multiple generations of selective breeding and evaluation before finalizing the variety. The breeding program performed preliminary crosses between parent plants with specific chemotypes, followed by systematic selection and evaluation over multiple generations to establish the stable 1:1 THC:THCV ratio before asexual propagation, ensuring the desired chemical characteristics are fixed prior to commercial production
Solution Approach 2:
The patent applies parameter changes by deliberately selecting and maintaining specific cannabinoid concentration ratios (THC:THCV = 1:1) through controlled breeding. The breeding program manipulated chemical composition parameters by crossing parent plants with different chemotypes and selecting progeny that exhibited the target parameter range, thereby achieving the desired medicinal profile
2Reliability
If asexual propagation is used to reproduce true-to-type plants, then the reliability of chemotypic characteristics is improved, but the time required for variety development and evaluation increases
Solution Approach 1:
The patent applies preliminary action by completing multiple generations of sexual breeding and selection before initiating asexual propagation. The variety underwent preliminary evaluation including chemotype characterization, morphological assessment, and propagation testing to ensure stability of characteristics before being released for commercial production, thereby reducing future development time
Solution Approach 2:
The patent applies copying by transitioning from sexual reproduction to asexual propagation (cloning) to reproduce the variety. Once the desired chemotypic characteristics were established through breeding, the variety was propagated asexually to create genetically identical copies that reliably reproduce the target THC:THCV ratio and other characteristics without further breeding cycles

AI summary
The unique annual herbaceous Cannabis plant variety ‘ESB-1’ is provided. The variety can be distinguished by its outstanding features of a THCV cannabinoid content ratio of about 1 part THC to 1 part THCV and purple leaf stem, when grown under certain growing conditions.
