Esm Cantata Rose Cultivar Breeding Novel Colors Longevity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cut flower Rose varieties lack novel and attractive flower colors and exhibit inadequate postproduction longevity, necessitating the development of new freely-flowering varieties with improved characteristics.
Innovation Solution
The Rosa hybrida cultivar 'Esm Cantata' is bred through controlled cross-pollination, exhibiting unique traits such as long upright stems, durable foliage, yellow-green-red flower colors, and excellent postproduction longevity, distinguishing it from its parent selections and comparable cultivars like Golden Gate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional Rose varieties are used for cut flowers, then they are readily available, but they lack novel and attractive flower colors and have inadequate postproduction longevity
Solution Approach 1:
The patent applies parameter changes by developing new Rose cultivars with modified genetic parameters that result in novel flower colors (yellow-green-red combinations) and extended postproduction longevity. The breeding program specifically selected for these altered parameters, creating varieties that simultaneously achieve both novel colors and improved longevity beyond conventional varieties.
Solution Approach 2:
The patent employs composite materials by creating hybrid Rose varieties through controlled cross-pollination that combine desirable traits from different parent selections. The resulting cultivars integrate multiple genetic characteristics including novel color pigments and longevity-enhancing traits, effectively combining multiple beneficial properties into a single improved variety.
2Reliability
If new Rose cultivars are developed through breeding programs, then novel flower colors and improved longevity are achieved, but the breeding and development process becomes complex and time-consuming
Solution Approach 1:
The patent applies preliminary action by conducting controlled cross-pollination and selecting specific parent selections with desired traits before the breeding process begins. The inventor pre-selected parent plants code 93 and code 95 based on their promising characteristics, and performed the cross-pollination in a controlled environment to streamline the development process and reduce subsequent complexity.
Solution Approach 2:
The patent employs self-service by allowing the selected Rose plant to self-propagate through asexual reproduction by cuttings. Once the desired cultivar characteristics were established through controlled breeding, the variety demonstrated stable inheritance and true-to-type reproduction through vegetative propagation, eliminating the need for continued complex breeding interventions.
3Area of moving object
If Rose varieties are selected for large flower size, then aesthetic value is improved, but stem length and overall plant structure may be compromised
Solution Approach 1:
The patent applies parameter changes by developing a new cultivar that simultaneously alters multiple growth parameters. The resulting Rose variety achieves both increased flower size (larger than parent selections) and maintained or improved stem length, demonstrating that parameter changes can produce multiple beneficial outcomes rather than trade-offs when proper genetic selection is applied.
