Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cut flower Rose varieties often lack attractive flowers with excellent postproduction longevity and are susceptible to environmental variations and pathogens like Botrytis, limiting their stability and market appeal.
Innovation Solution
The development of Rosa hybrida cultivar 'ESM R136' through controlled breeding, which exhibits upright and strong flowering stems, bright red-colored spray-type flowers, high productivity, and tolerance to Botrytis, maintaining longevity both on the plant and as a cut flower.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional cut flower Rose varieties are used, then they may have acceptable flower appearance, but they lack excellent postproduction longevity and are susceptible to Botrytis
Solution Approach 1:
The patent applies parameter changes by developing a new Rose cultivar with modified genetic parameters that simultaneously improve postproduction longevity and Botrytis tolerance. The breeding program selected for specific traits including extended vase life and pathogen resistance, resulting in a cultivar that maintains freshness longer and withstands Botrytis infection better than conventional varieties.
2Stability of the object's composition
If conventional Rose varieties are used, then they may have acceptable growth habits, but they lack stability under environmental variations
Solution Approach 1:
The patent employs parameter changes through selective breeding to modify the Rose cultivar's genetic parameters for environmental stability. The new cultivar exhibits consistent growth habits, flowering patterns, and flower quality across varying environmental conditions, demonstrating improved reliability and performance consistency compared to conventional varieties.
3Productivity
If existing Rose varieties are used, then they may have moderate productivity, but they lack attractive flowers with excellent postproduction longevity
Solution Approach 1:
The patent applies parameter changes by breeding a Rose cultivar with optimized genetic parameters that simultaneously enhance productivity and flower longevity. The new cultivar produces abundant flowers with extended vase life, resolving the trade-off between production volume and postproduction durability that limits conventional varieties.
