Meizambaizt Rose Plant Breeding via Preliminary Parent Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new variety of Rosa hybrida Grandiflora rose plant that combines strong vegetation, dense dark green foliage, abundant and continuous double cup-shaped yellow blossoms, and excellent disease tolerance, particularly to black spot, while offering distinctive ornamental value for horticultural use.
Innovation Solution
The new variety 'Meizambaizt' was created through artificial pollination of 'Macivy' and 'Wekamanda' rose parents, resulting in a bushy growth habit with dense glossy foliage and exceptional blooming capabilities, suitable for asexual propagation and disease resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If artificial pollination is performed to combine desired characteristics from parent varieties, then the ornamental value and disease tolerance are improved, but the breeding complexity and time required are increased
Solution Approach 1:
The patent applies preliminary action by carefully selecting and preparing parent plants with specific desired characteristics before performing the cross-pollination. The female parent was selected for strong vegetation and disease tolerance, while the male parent was selected for yellow blossom coloration. This preliminary selection and preparation of parental materials with predetermined traits allows the breeding process to efficiently produce offspring with the desired combination of characteristics, reducing overall breeding complexity.
2Manufacturing precision
If selective study is performed to identify a single plant from multiple seedlings, then the quality and distinctiveness of the new variety is improved, but the time and resources required for selection are increased
Solution Approach 1:
The patent applies color changes as a selection criterion by focusing on the distinctive yellow blossom coloration with golden-yellow outer petals and lighter yellow inner petals that differentiates the new variety from its parents. The female parent had red blossoms with yellow near the base, and the male parent had light yellow blossoms with greenish hue on outer petals. The new variety's unique color pattern served as a clear visual marker for identification and selection, enabling efficient distinction of the desired phenotype among seedlings.
3Stability of the object's composition
If the new variety is propagated asexually through budding, grafting, or cuttings, then the stability and transmissibility of characteristics are improved, but the propagation complexity is increased
Solution Approach 1:
The patent applies copying through asexual propagation methods where exact genetic copies of the selected plant are produced. Through budding, grafting, or cuttings, the new variety's distinctive characteristics (yellow cup-shaped blossoms, dense glossy foliage, disease tolerance) are replicated faithfully without genetic variation. This copying process ensures that the unique combination of traits identified in the selected plant is precisely transmitted to subsequent generations, maintaining characteristic stability.
