Furano 0902D Go Hop Variety Breeding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new and distinct variety of hop that exhibits specific characteristics such as cylindrical plant shape, high alpha acid content, balanced beta to alpha acid ratio, and unique flavor profile, which are not met by existing hop varieties.
Innovation Solution
The development of the hop variety 'Furano 0902D go' through controlled cross-pollination of proprietary female and male hop parents, resulting in a plant that reproduces true to type via vegetative propagation, with characteristics including 13.4% alpha acid content, 0.6 beta to alpha ratio, 32% cohumulone content, and a flowery and fruity flavor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If controlled cross-pollination is performed to achieve specific chemical characteristics (13.4% alpha acid, 0.6 beta to alpha ratio), then the brewing quality is improved, but the breeding process complexity increases
Solution Approach 1:
The patent applies preliminary action by performing controlled cross-pollination between specifically selected parent lines ('990340' and '000210') before harvesting to ensure the desired chemical characteristics are established in the F1 generation. The parent lines were pre-selected for their complementary traits, and the cross-pollination was conducted under controlled conditions to guarantee the target alpha acid content of 13.4% and beta to alpha ratio of 0.6.
2Stability of the object's composition
If vegetative propagation is used to maintain genetic stability, then the variety reproduces true to type, but the propagation time and labor requirements increase
Solution Approach 1:
The patent applies self-service by utilizing vegetative propagation through cuttings that naturally root and develop into true-to-type plants without requiring complex tissue culture facilities or sophisticated propagation techniques. The cuttings self-root and develop into complete plants, maintaining genetic stability through natural asexual reproduction mechanisms while minimizing external intervention and time investment.
3Quantity of substance
If the hop variety is optimized for high alpha acid content (13.4%), then the brewing utility is improved, but the yield per hectare may be reduced
Solution Approach 1:
The patent applies parameter changes by optimizing multiple chemical parameters simultaneously in the 'Furano 0902D go' variety: alpha acid content is set at 13.4%, beta acid content at 5.9% (giving a beta to alpha ratio of 0.6), and cohumulone content at 32% of total alpha acids. This multi-parameter optimization approach balances brewing utility with productivity, ensuring the variety meets both quality specifications and commercial yield requirements.
