Viburnum Redell Cultivar Breeding for Dense Fruit Clusters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new Viburnum plants with unique and attractive foliage and flower coloration that can reproduce stably through asexual methods, offering improved compactness, denser fruit clusters, and uniform fruit color compared to existing varieties.
Innovation Solution
The development of a new Viburnum hybrida cultivar, 'Redell', resulting from a planned breeding program combining Viburnum burejaeticum 'Emerald Triumph' as the female parent and an unknown Viburnum hybrida selection as the male parent, exhibiting an upright, freely branching habit with white flowers and dense red fruit clusters, achieved through softwood cuttings for asexual reproduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If asexual reproduction by softwood cuttings is used, then stable reproduction of unique traits is achieved, but propagation time and effort increase
Solution Approach 1:
The patent performs preliminary selection and identification of superior plants exhibiting desired traits (compact growth, dense fruit clusters, uniform fruit color) before propagation. By pre-selecting the optimal parent plant and confirming its stable trait expression through preliminary asexual reproduction testing, the patent ensures that subsequent large-scale propagation will yield consistent results, reducing the need for repeated selection cycles and thereby reducing overall propagation time.
2Ease of manufacture
If breeding programs focus on unique foliage and flower coloration, then plant attractiveness is improved, but breeding complexity increases
Solution Approach 1:
The patent segments the breeding objective into distinct, measurable traits: compact growth habit, dense fruit clusters, and uniform fruit color. By breaking down the complex goal of creating an attractive ornamental plant into separate selectable characteristics, the breeding program can systematically evaluate and select for each trait independently, simplifying the overall breeding process while achieving multiple desirable features simultaneously.
Solution Approach 2:
The patent applies local quality by focusing selection on specific parts of the plant that contribute to attractiveness: fruit cluster density and uniformity, growth habit compactness, and fruit color consistency. Rather than attempting to improve all plant characteristics equally, the breeding program concentrates effort on these key local features that most significantly impact ornamental value, thereby simplifying the breeding approach while maximizing aesthetic appeal.
