Buddleja Hybrid 'Bosedaze' Cross-Pollination for Repeat Blooming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Buddleja cultivars lack distinctive flower coloration and well-branched habits with repeat blooming, limiting their ornamental appeal and versatility in landscaping.
Innovation Solution
The development of Buddleja hybrid cultivar 'Bosedaze' through controlled cross-pollination between 'Attraction' and 'Miss Ruby', resulting in dark red-purple flowers, dark green foliage, and a moderately vigorous, upright growth habit with larger inflorescences and leaves, enhancing its branching and flowering characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing Buddleja cultivars are used, then they have simple growth habits and smaller inflorescences, but they lack distinctive flower coloration and well-branched habits with repeat blooming
Solution Approach 1:
The patent combines multiple desirable traits from two parent cultivars through controlled cross-pollination. The female parent 'Attraction' contributes dark red-purple flower coloration and vigorous growth, while the male parent 'Miss Ruby' contributes compact-upright habit and repeat blooming. The resulting hybrid 'Bosedaze' merges these characteristics to achieve distinctive ornamental appeal with well-branched habits and repeat blooming capability.
2Quantity of substance
If the new cultivar 'Bosedaze' is developed through cross-pollination, then it has larger inflorescences and distinct dark red-purple coloration, but it requires controlled breeding programs and asexual reproduction for propagation
Solution Approach 1:
The patent performs preliminary controlled cross-pollination in a controlled breeding program to establish the desired genetic combination before large-scale propagation. The new cultivar was discovered and selected as a single flowering plant within the progeny during August 2012, then propagated asexually through terminal stem cuttings since August 2012. This preliminary development phase ensures the cultivar reproduces true to type with all characteristics firmly fixed and retained through successive generations.
3Adaptability or versatility
If Buddleja cultivars are bred for distinctive flower coloration and well-branched habits, then they achieve improved ornamental value, but they require controlled breeding programs and time for development
Solution Approach 1:
The controlled breeding program was initiated in September 2011 with the specific objective of developing Buddleja having distinctive flower coloration, good repeat blooming, and well-branched habits. The cross-pollination between 'Attraction' and 'Miss Ruby' was performed in advance, and the new cultivar was discovered and selected during August 2012. This preliminary breeding phase, though time-consuming, establishes the genetic foundation for improved ornamental value that is then preserved through asexual propagation.
