Compact Asiatic Lily Cultivar Breeding for Flower Longevity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new compact potted Asiatic Hybrid Lily plants with large attractive flowers and improved postproduction longevity, as existing varieties may not meet these criteria effectively.
Innovation Solution
The development of a new Asiatic Hybrid Lily cultivar, 'Tiny Nugget', which results from a controlled breeding program, exhibiting a compact and upright growth habit, vigorous growth, early flowering, yellow orange-colored flowers with greyed red spots, and good postproduction longevity, distinguishing it from its parent selections and other varieties like 'Tiny Sensation'.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If existing Asiatic Hybrid Lily varieties are used, then they may have acceptable flower size and color, but they lack improved postproduction longevity and compact growth habit
Solution Approach 1:
The patent applies parameter changes by selecting and breeding lily plants with specific quantitative traits: compact plant height (15-30 cm), increased postproduction longevity (10-15 days), and optimized flower size (8-15 cm diameter). These parameter modifications resolve the contradiction by creating a new cultivar that extends flower longevity while maintaining compact growth, directly addressing the limitation of existing varieties.
2Volume of moving object
If lily plants are made more compact for potted growth, then they become suitable for container gardening, but flower size may be reduced
Solution Approach 1:
The patent resolves this contradiction through careful parameter optimization: plant height is controlled at 15-30 cm for compactness, while flower diameter is maintained at 8-15 cm through selective breeding. The cultivar achieves this balance by changing the scaling relationship between plant and flower parameters, allowing large flowers to develop on compact plants rather than requiring proportional reduction.
3Volume of moving object
If breeding programs focus on compact growth habit, then potted plant suitability improves, but flowering time may be delayed
Solution Approach 1:
The patent addresses this contradiction by independently optimizing growth habit parameters and flowering time parameters through multi-generation selective breeding. The cultivar maintains early flowering (60-90 days from bulb planting) while achieving compactness (15-30 cm height), resolving the time loss issue by decoupling the relationship between compact growth and flowering timing through careful gene selection.
