Hemerocallis 'Huhe01' Hybrid with Extended Flower Duration
Solution Overview
Problem
There is a need for a new cultivar of Hemerocallis that offers longer-lasting flowers with unique coloration and healthy foliage, as existing cultivars like 'Summer Dragon', 'Green Flutter', and 'Condilla' have limitations such as short-lasting flowers and different flower characteristics.
Innovation Solution
The development of Hemerocallis 'Huhe01', a hybrid cultivar resulting from pollination between 'Summer Dragon' and proprietary plants, which exhibits flowers lasting over 7 days, unique lime-green-yellow to orange coloration, and blue-green foliage, achieved through asexual propagation by division and tissue culture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If existing Hemerocallis cultivars like 'Summer Dragon' are used, then breeding programs have available material, but the flowers last only 1 day
Solution Approach 1:
The patent applies parameter changes by crossing cultivars with different flowering duration parameters to produce offspring with extended flower longevity. The cross between 'Summer Dragon' (1-day flowers) and the proprietary plant resulted in 'Huhe01' with 7+ day flowers, demonstrating change in the duration parameter through controlled breeding.
2Duration of action of moving object
If existing cultivars like 'Green Flutter' are used, then yellow-green flowers with green throat are obtained, but they last only 1 day
Solution Approach 1:
The patent changes the coloration parameter from simple yellow-green with green throat to a complex gradient of lime-green-yellow transitioning to orange. This parameter change in flower coloration is achieved through hybridization and results in the unique multi-stage coloration of 'Huhe01' that lasts throughout the extended flowering period.
3Duration of action of moving object
If existing cultivars like 'Condilla' are used, then double orange flowers are obtained, but they last only up to 30 hours
Solution Approach 1:
The patent changes the flower structure parameter from double flowers to single flowers, and simultaneously changes the duration parameter from 30 hours to 7+ days. The single flower structure of 'Huhe01' with its specific petal arrangement and throat morphology represents a parameter change that correlates with the extended flowering duration.
4Duration of action of moving object
If existing cultivars are used, then standard foliage is obtained, but unique coloration and extended flower duration are not achieved
Solution Approach 1:
The patent applies multiple parameter changes simultaneously: flower duration (1 day to 7+ days), coloration (standard to lime-green-yellow to orange gradient), and foliage characteristics (standard to blue-green). These coordinated parameter changes in the 'Huhe01' cultivar achieve the desired improvements while maintaining plant health and vigor.
