Mandevilla Sunparapibra Cultivar Branch Mutation Traits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new and distinct cultivar of Mandevilla hybrida that exhibits unique characteristics such as upright and vining plant habit, small glossy foliage, light pink-colored flowers, and a long flowering period, which are not met by existing cultivars like Sunmandecrim, Sunparabeni, and Sunparavel, and differs significantly from Sunmandecos in leaf length, flowering frequency, and flower color.
Innovation Solution
The cultivar 'Sunparapibra' is a naturally occurring branch mutation of Mandevilla hybrida's Sunmandecrim, characterized by its stable reproduction through cuttings, displaying distinct traits like darker green leaves, light pink flowers, and a prolonged flowering period, distinguishing it from other Mandevilla cultivars.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a new Mandevilla cultivar is developed with upright and vining habit, then plant form is improved, but breeding complexity increases
Solution Approach 1:
The invention utilizes a naturally occurring branch mutation that changed the plant habit parameters from the original Sunmandecrim cultivar. This mutation resulted in an upright and vining habit while maintaining other desirable traits, achieving the desired plant form through natural variation rather than complex breeding programs
2Shape
If flower color is changed to light pink, then aesthetic appeal is improved, but genetic stability becomes more challenging
Solution Approach 1:
The invention captures a naturally occurring mutation that changed the flower color parameter from red to light pink. This color variation was identified and selected from a population of Sunmandecrim plants, and subsequent asexual reproduction has demonstrated stable inheritance of this color trait
Solution Approach 2:
The invention utilizes asexual reproduction by cuttings to propagate the new cultivar. This copying method ensures genetic stability and true-to-type reproduction of the light pink flower color without the variability associated with sexual reproduction
3Duration of action of moving object
If flowering period is extended, then ornamental value is improved, but physiological stress increases
Solution Approach 1:
The new cultivar exhibits a naturally extended flowering period parameter compared to the parent cultivar. This prolonged flowering duration is achieved through the branch mutation while the plant maintains healthy physiology and shows no signs of increased stress
4Shape
If leaf color is changed to darker green, then foliage appeal is improved, but photosynthetic efficiency may be reduced
Solution Approach 1:
The invention captures a natural mutation that changed the leaf color parameter to a darker green shade. The plant maintains vigorous growth and healthy foliage, suggesting that the photosynthetic efficiency is sufficient to support the darker pigmentation without compromising overall plant health
