Iberis Doibewhisha Cultivar Breeding for Flower Size and Timing
Solution Overview
Problem
Current Iberis sempervirens cultivars lack desirable traits such as large flowers, late flowering, and robust growth habits, which are essential for improved horticultural performance and aesthetic appeal.
Innovation Solution
A new cultivar, 'Doibewhisha', resulting from a breeding program that combines compact, upright growth with freely branching and dense inflorescences, featuring larger white flowers and improved container and garden performance, achieved through open-pollination and subsequent vegetative propagation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If traditional Iberis sempervirens cultivars are used, then early flowering is achieved, but flower size remains small and growth habit is less vigorous
Solution Approach 1:
The breeding program systematically altered genetic parameters through controlled open-pollination between selected parent plants, resulting in progeny with modified flowering time and flower size characteristics. The new cultivar exhibits both later flowering and larger flowers simultaneously, resolving the trade-off between these two parameters.
2Volume of moving object
If compact growth habit is selected, then plant size is controlled, but branching density and inflorescence density may be reduced
Solution Approach 1:
The new cultivar exhibits differentiated local qualities within its compact form: the overall plant maintains a controlled mounding habit suitable for containers, while specific regions (branching zones) display enhanced freedom of branching and dense inflorescence formation. This local differentiation allows simultaneous achievement of compact size and high inflorescence density.
