Gerbera Garkendall Cultivar Cold Tolerance and Compact Habit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for compact garden Gerbera plants with attractive inflorescences that are resistant to cold temperatures and exhibit good garden performance, as existing varieties may lack these traits or have variations in appearance under different environmental conditions.
Innovation Solution
A new Gerbera hybrida cultivar 'Garkendall' is developed through planned breeding, characterized by a compact, upright plant habit, dense inflorescences with dark orange-red ray florets, strong scapes, and tolerance to cold temperatures, achieved through cross-pollination of proprietary selections 09T231 and 09T193, and stabilized through asexual reproduction by cuttings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing Gerbera varieties are used, then they may have attractive inflorescences, but they lack cold temperature resistance and good garden performance
Solution Approach 1:
The patent applies parameter changes by selecting and breeding plants with specific genetic parameters that confer cold temperature resistance while maintaining garden performance. The breeding program specifically targets and selects for plants exhibiting both cold hardiness and good garden performance traits, thereby changing the genetic parameters of the Gerbera population to resolve the contradiction between temperature resistance and adaptability.
2Shape
If Gerbera plants are bred for compact habit, then they achieve desirable plant form, but may reduce inflorescence size or number
Solution Approach 1:
The patent applies local quality by differentiating the desired traits in different parts of the plant: compactness and upright habit in the vegetative portion, while maintaining numerous inflorescences in the reproductive portion. The breeding program selects for plants that exhibit compact basal foliage with upright, strong scapes that bear multiple inflorescences, thereby achieving local optimization of both plant habit and inflorescence production.
3Quantity of substance
If Gerbera plants are bred for numerous inflorescences, then they achieve high flower production, but may lose cold temperature tolerance
Solution Approach 1:
The patent applies merging by combining multiple desirable traits from different parent lines into a single unified cultivar. The breeding program crosses plants with high inflorescence production capabilities with plants exhibiting cold temperature resistance, then selects progeny that inherit both traits simultaneously, thereby merging previously separate trait combinations into one integrated plant type.
