PACfive Miniature Rose Breeding for Greenhouse Uniformity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing commercial miniature rose cultivars lack uniform and abundant flowers with good keepability, attractive long-lasting foliage, compact growth, year-round flowering under glasshouse conditions, and suitability for production from softwood cuttings, making them unsuitable for commercial greenhouse culture and the floral industry.
Innovation Solution
Development of a new miniature rose variety, 'PACfive', achieved through artificial pollination, characterized by medium double red flowers, compact growth, and resistance to diseases, specifically bred for commercial greenhouse culture to meet the requirements of uniform flowers, attractive foliage, and year-round flowering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing commercial miniature rose cultivars are used, then they are available for market, but they lack uniform and abundant flowers with good keepability, attractive long-lasting foliage, compact growth, year-round flowering capability, and suitability for production from softwood cuttings
Solution Approach 1:
The patent applies parameter changes by selectively breeding for specific traits including flower uniformity, abundance, keepability, foliage attractiveness, compact growth habit, year-round flowering capability, and cutting propagation suitability. The variety 'PACfive' represents a optimized combination of these parameters that resolves the contradiction between reliability and adaptability for commercial greenhouse production
2Stability of the object's composition
If existing miniature rose cultivars are used, then they can be propagated, but they do not demonstrate true-to-type characteristics in asexual reproduction
Solution Approach 1:
The patent employs softwood cutting propagation method which is a cost-effective and efficient asexual reproduction technique. The variety 'PACfive' is specifically selected to demonstrate true-to-type characteristics when propagated through this method, ensuring both genetic stability and commercial productivity
3Duration of action of stationary object
If existing rose varieties are used, then they may have some flowering capability, but they lack year-round flowering under glasshouse conditions
Solution Approach 1:
The variety 'PACfive' possesses inherent traits that enable year-round flowering under glasshouse conditions without requiring complex management interventions. The plant self-regulates its flowering cycle to produce uniform blooms throughout the year, reducing the need for sophisticated environmental control systems
