Peni Vio09 Penstemon Cultivar Breeding for Compact Growth
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new Penstemon hartwegii cultivar that exhibits earlier flowering, medium-compact growth habit, and strong stems, as existing varieties like 'Pheni Vio' are taller, later to flower, and have less vigor.
Innovation Solution
The development of 'Peni Vio09' through controlled hybridization in a breeding program, combining the desirable traits of a patented hybrid seedling 'Pheni Vio' with an unpatented hybrid seedling '104-1', resulting in a cultivar with darker purple flowers, more compact growth, and enhanced flowering habit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the variety 'Pheni Vio' is used, then the plant has a taller habit and lighter purple color, but it flowers later and has less vigor
Solution Approach 1:
The patent applies parameter changes by hybridizing two parent varieties with different genetic parameters to produce offspring with improved characteristics. The cross between 'Pheni Vio' and '104-1' resulted in 'Peni Vio09' which exhibits earlier flowering and stronger vigor, demonstrating changes in biological parameters through selective breeding.
2Length of stationary object
If the variety 'Pheni Vio' is used, then the plant has a taller habit, but it is less compact and later to flower
Solution Approach 1:
The patent applies local quality by creating a variety with differentiated growth characteristics - 'Peni Vio09' has a medium-compact growth habit with strong stems and upright posture, distinguishing different parts of the plant structure. The variety maintains appropriate height while improving compactness and flowering timing through selective breeding.
3Manufacturing precision
If hybridization between 'Pheni Vio' and '104-1' is performed, then darker purple flowers and medium-compact growth are achieved, but the breeding process requires controlled environment and multiple generations
Solution Approach 1:
The patent applies preliminary action by conducting controlled hybridization in a regulated breeding program, performing pollination and seed collection in advance under controlled conditions. The preliminary crossing of 'Pheni Vio' and '104-1' in 2005, followed by selection and vegetative propagation, ensured the fixation of desirable traits including darker purple flower color and medium-compact growth before commercial release.
