Hypericum Kolmapuki Cultivar Stem Strength and Rust Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Hypericum cultivars lack strong stems, uniform flowering, high fruit density, and resistance to Puccinia rust, particularly in pot-type plants.
Innovation Solution
The development of a new Hypericum×inodorum cultivar, 'Kolmapuki', resulting from a controlled cross-pollination, which exhibits upright growth, small dark green leaves, orange fruits, and resistance to Puccinia rust, with stable asexual reproduction via vegetative cuttings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing Hypericum cultivars are used, then they are available for cultivation, but they lack resistance to Puccinia rust and have weak stems
Solution Approach 1:
The patent applies composite breeding by crossing two different Hypericum×inodorum selections (code 261-01 and code 229-04) to combine desirable traits. The resulting cultivar 'Kolmapuki' exhibits both strong stems and Puccinia rust resistance, resolving the contradiction between these two features that were absent in existing cultivars.
2Productivity
If existing Hypericum cultivars are used, then they can be grown, but they lack uniform flowering and high fruit density
Solution Approach 1:
Through composite breeding of two parent selections, the patent achieves both uniform flowering habit and high fruit density in cultivar 'Kolmapuki'. The cross-pollination combined genetic traits that ensure uniform flower distribution and dense fruit set, resolving the contradiction between productivity and compositional stability.
3Use of energy by moving object
If larger leaves are present, then more photosynthesis can occur, but the plant loses its compact pot-type appearance
Solution Approach 1:
The patent applies parameter changes by selecting for smaller leaf size in cultivar 'Kolmapuki' while maintaining adequate photosynthetic capacity through increased leaf density or surface area-to-volume ratio. This resolves the contradiction between energy production and compact shape suitable for pot-type cultivation.
