Sunny Robyn Lily Cultivar Compact Habit Longevity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing cultivars of Oriental Hybrid Lilies lack compact, attractive flower options with good post-production longevity, which limits their commercial appeal and adaptability in diverse environmental conditions.
Innovation Solution
A new cultivar, 'Sunny Robyn', is developed through planned breeding, characterized by a compact upright habit, vigorous growth, short leaves, freely flowering habit, pink-colored flowers with white margins, and excellent post-production longevity, distinguishing it from parent selections and similar cultivars like 'Sunny Borneo'.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If existing Oriental Hybrid Lily cultivars are used, then they have certain flower size and color characteristics, but they lack compactness and have poor post-production longevity
Solution Approach 1:
The patent applies parameter changes by selectively breeding for specific morphological parameters including plant height (45-60 cm), flower diameter (12-18 cm), and petal color intensity. The cultivar 'Sunny Robyn' achieves improved post-production longevity through optimized genetic parameters while maintaining compact dimensions of 45-60 cm plant height, representing a deliberate parameter transformation from parent cultivars
2Productivity
If existing Oriental Hybrid Lily cultivars are used, then they have certain growth habits, but they lack vigorous growth and freely flowering habit
Solution Approach 1:
The cultivar exhibits self-service characteristics through its vigorous growth habit that requires minimal intervention. The plant naturally maintains healthy foliage, produces multiple flowers per stem (3-5 flowers), and recovers well from flowering without extensive cultural requirements, embodying the self-service principle where the plant sustains itself with standard care
3Shape
If existing Oriental Hybrid Lily cultivars are used, then they have certain leaf characteristics, but they lack short broad leaves with attractive appearance
Solution Approach 1:
The patent applies local quality by optimizing specific leaf characteristics including length (7-12 cm), width (2-4 cm), and color (dark green, glossy). The leaves exhibit differentiated properties with serrated margins, prominent venation, and varying dimensions along the stem, creating localized aesthetic quality that enhances overall plant appearance without requiring complex breeding protocols
