Begonia Bbmil Cultivar Compact Growth Double Yellow Flowers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a distinct cultivar of Begonia×hiemalis that exhibits unique characteristics such as compact growth, abundant double yellow flowers, and tolerance to varying environmental conditions, which are not met by existing cultivars like Bbnes and Nadine.
Innovation Solution
A naturally occurring mutation of Begonia×hiemalis, designated as 'Bbmil', which features a compact, upright growth habit, freely branching stems, and bright yellow double flowers, distinguished by its genotype stability across environmental variations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a Begonia cultivar is selected for abundant flower production, then the number of flowers increases, but the plant size becomes larger and less compact
Solution Approach 1:
The patent applies parameter changes by selecting a mutant plant with altered genetic parameters that result in a compact growth habit while maintaining abundant flower production. The mutant 'Bbmil' exhibits changed parameters in plant architecture (compact, upright form) and flower production (abundant double flowers), resolving the contradiction between plant size and flower quantity through natural mutation and selection rather than traditional breeding or chemical intervention.
2Area of moving object
If a Begonia cultivar is selected for large flower size, then individual flower dimensions increase, but the number of flowers per plant decreases
Solution Approach 1:
The patent resolves this contradiction through parameter changes in the mutant plant 'Bbmil', which exhibits altered developmental parameters allowing simultaneous production of numerous double flowers with adequate size. The mutant's changed genetic parameters enable increased flower density and double flower formation without sacrificing individual flower dimensions, achieving both large flower size and high flower number.
3Productivity
If a Begonia cultivar is selected for vigorous growth, then growth rate increases, but the plant becomes less compact and harder to manage
Solution Approach 1:
The patent applies parameter changes by selecting a mutant with altered growth parameters that produce a compact, upright plant habit. The mutant 'Bbmil' exhibits changed parameters in growth architecture (compact form, upright habit, freely branching) that maintain moderate growth rate while improving manageability and reducing plant complexity, making the plant easier to cultivate and market.
4Device complexity
If a Begonia cultivar is selected for single flowers, then flower structure is simpler, but aesthetic value and market appeal decrease
Solution Approach 1:
The patent resolves this contradiction through parameter changes in the mutant plant that naturally produces double flowers. The mutant 'Bbmil' exhibits changed parameters in flower development resulting in double flower formation (multiple floral whorls), which increases aesthetic value and market appeal while maintaining a compact plant habit that is easy to manage, thus improving both attractiveness and manageability simultaneously.
