PCT11204V Cannabis Variety Elevating THCV Levels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cannabis plants naturally have low levels of varin cannabinoids, such as THCV and CBDV, limiting research and product development due to their rarity, which hampers the creation of high-margin medical and recreational products with distinct pharmacological profiles.
Innovation Solution
A novel Cannabis sativa variety, 'PCT11204V', is developed through selective breeding and marker-assisted selection to elevate THCV levels, achieved by crossing high THCV pollen receiver and THC pollen donor plants, ensuring consistent and high production of varins through asexual propagation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If conventional Cannabis plants are used, then cultivation is simple and well-established, but varin levels (THCV, CBDV) are naturally low limiting product development
Solution Approach 1:
The patent applies preliminary action by pre-establishing a structured breeding program with defined parental lines (high THCV receiver × high THC donor) and marker-assisted selection protocols before large-scale production. This preliminary setup enables systematic elevation of varin levels across generations without ad-hoc complexity during production
Solution Approach 2:
The patent implements feedback through marker-assisted selection where molecular markers are used to track and select for elevated THCV and CBDV levels in progeny. This feedback mechanism ensures that breeding efforts consistently achieve the desired varin concentration targets, resolving the contradiction between increased varin levels and breeding complexity
2Quantity of substance
If selective breeding and marker-assisted selection are used to elevate THCV levels, then varin production increases, but breeding and selection time increases
Solution Approach 1:
The patent replaces traditional mechanical/phenotypic selection methods with marker-assisted selection using molecular markers. This substitution accelerates the breeding process by enabling early-generation selection based on genetic markers rather than waiting for phenotypic expression, significantly reducing the time required to develop high-THCV varieties while maintaining selection precision
Solution Approach 2:
The patent changes the selection parameter from phenotypic observation to molecular marker detection. By using DNA markers linked to THCV synthesis genes, the breeding program can select for elevated THCV content at the molecular level, accelerating the breeding timeline while achieving the desired parameter changes in varin production
3Stability of the object's composition
If asexual propagation is used to fix genetic loci, then genetic stability is improved, but propagation infrastructure requirements increase
Solution Approach 1:
The patent applies self-service by using asexual propagation through vegetative cuttings that naturally maintain genetic fidelity without requiring complex intervention. The cloned plants inherently preserve the fixed genetic loci for THCV synthesis, achieving genetic stability through the biological self-service of clonal reproduction rather than requiring elaborate external control systems
