Mandevilla Gendipsa Double Flower Compact Habit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Mandevilla cultivars lack double flowers and compact growth habits, which are desirable traits for horticultural applications.
Innovation Solution
The development of the Mandevilla×amabilis cultivar 'Gendipsa' through hybridization of proprietary selections 'DP 524' and 'DP 100', resulting in double red-purple flowers and a compact growth habit, achieved through asexual reproduction by terminal cuttings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If conventional Mandevilla cultivars are used, then the plants are easy to propagate and maintain, but they lack double flowers and compact growth habits
Solution Approach 1:
The patent applies parameter changes by hybridizing two proprietary Mandevilla selections (DP 524 and DP 100) to create a new cultivar with fundamentally different floral parameters - specifically producing double flowers with multiple petal whorls instead of single or semi-double flowers, and achieving a compact growth habit with shorter internodes. This parameter transformation resolves the contradiction by creating a cultivar that simultaneously achieves the desired double flower structure and compact form while maintaining horticultural adaptability.
Solution Approach 2:
The patent employs composite materials by combining genetic material from two distinct Mandevilla parental lines to create a composite cultivar. The hybridization of DP 524 (female parent) and DP 100 (male parent) produces a composite genetic structure that integrates traits for double flower formation and compact growth habit, resolving the technical contradiction by synthesizing multiple desirable characteristics into a single unified cultivar.
2Shape
If Mandevilla cultivars with double flowers are developed, then aesthetic appeal is improved, but growth habit becomes less compact
Solution Approach 1:
The patent resolves this contradiction through parameter changes by establishing a new genetic parameter set in the Gendipsa cultivar where double flower complexity and compact stature coexist. The hybridization process created a cultivar with internodes measuring 5-10 cm (compact) while simultaneously producing double flowers with 2-3 whorls of petals. This dual parameter transformation overcomes the typical trade-off between flower complexity and plant size.
Solution Approach 2:
The patent applies local quality by differentiating the expression of traits in different parts of the plant - the flowering structures exhibit high complexity with multiple petal whorls while the vegetative structures (stems and internodes) maintain compact dimensions. This spatial differentiation of trait expression allows the plant to simultaneously achieve elaborate flowers and compact overall size, resolving the contradiction between these two characteristics.
3Manufacturing precision
If proprietary parental selections are hybridized, then unique cultivar characteristics are achieved, but breeding complexity increases
Solution Approach 1:
The patent applies self-service by developing a breeding program where the proprietary parental selections (DP 524 and DP 100) were specifically chosen and crossed to automatically produce the desired double flower and compact habit traits in the progeny. The Gendipsa cultivar emerged through this controlled hybridization process with uniform expression of target characteristics, allowing the breeding system to self-generate the desired cultivar properties without requiring complex external intervention or ongoing maintenance of breeding infrastructure.
