Phygelius CROSNOQUE Cultivar Pure-White Flower Color
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a lack of Phygelius varieties with pure-white flowers, and existing cultivars often have varying flower colors and habits that do not meet specific horticultural requirements for compact upright growth and hardiness in USDA Zone 8.
Innovation Solution
A new Phygelius cultivar, 'CROSNOQUE', is developed through controlled cross-pollination between Phygelius aequalis and 'Yellow Trumpet', resulting in compact upright habit and pure-white flowers, suitable for USDA Zone 8, with stable characteristics maintained through asexual propagation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If existing Phygelius cultivars are used, then various flower colors are available, but pure-white flowers are not available and growth habit varies
Solution Approach 1:
The invention changes the genetic parameters of Phygelius aequalis through controlled cross-pollination to produce a new cultivar with pure-white flowers. By selecting specific parents and controlling the breeding process, the inventor achieved a stable pure-white flower color that distinguishes this cultivar from all other existing Phygelius varieties.
Solution Approach 2:
The invention applies local quality by focusing on specific traits (pure-white flower color and compact upright habit) while allowing other characteristics to vary. The new cultivar 'CROSNOQUE' was selected specifically for these localized qualities rather than attempting to optimize all characteristics simultaneously.
2Shape
If Phygelius varieties are bred for compact upright habit, then growth form is improved, but flower color consistency varies
Solution Approach 1:
The inventor performed preliminary selection of parent plants with desirable traits before conducting the cross-pollination. By pre-selecting parents with good upright habit and then selecting offspring with both upright habit and pure-white flowers, the inventor ensured trait uniformity in the final cultivar through advance planning and selection.
Solution Approach 2:
The breeding process incorporated feedback through multiple generations of selection and evaluation. The inventor assessed F1 plants and performed back-crosses, continuously evaluating plants for both growth habit and flower color consistency, and selecting only those that met both criteria for the final cultivar.
3Adaptability or versatility
If Phygelius is bred for hardiness in USDA Zone 8, then environmental adaptability is improved, but flower color and habit consistency may vary
Solution Approach 1:
The inventor pre-selected parent plants that demonstrated hardiness in USDA Zone 8 conditions before conducting the cross. By ensuring parents were adapted to the target environment, the F1 offspring inherited both hardiness and consistent phenotypic traits, resolving the contradiction between adaptability and consistency.
