Buddleja Balchryran Cultivar Compact Growth Habit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Buddleja cultivars lack distinct coloration, repeat blooming, and a highly branched, compact-mounded growth habit, which are desirable traits for horticultural applications.
Innovation Solution
The development of a new Buddleja hybrid cultivar, 'Balchryran', resulting from cross-pollination between proprietary breeding selections 3855-M and 3923-A, exhibiting deep reddish-purple flowers, dark green foliage, and a compact-mounded growth habit with lower growth vigor, achieved through asexual reproduction by terminal stem cuttings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If existing Buddleja cultivars are used, then they have moderate to high growth vigor, but they lack distinct coloration, repeat blooming, and compact-mounded growth habit
Solution Approach 1:
The patent applies parameter changes by selectively breeding to modify growth vigor and growth habit parameters. The new cultivar 'Balchryran' exhibits reduced growth vigor and a compact-mounded growth habit compared to parent plants, achieving the desired shape characteristics while maintaining health through controlled breeding parameters
2Shape
If Buddleja cultivars with distinct coloration and compact growth habit are developed, then aesthetic value is improved, but breeding complexity increases
Solution Approach 1:
The breeding program was segmented into distinct phases: selecting parent plants with specific traits (3855-M and 3923-A), controlled cross-pollination, progeny evaluation, and asexual propagation. This segmentation of the breeding process into manageable stages reduced overall program complexity while achieving the desired compact-mounded growth habit and distinct coloration
Solution Approach 2:
Once the desired traits were achieved in the flowering plant, the invention uses asexual reproduction by terminal stem cuttings to create exact copies of the cultivar. This copying method ensures true-to-type reproduction of the compact-mounded growth habit and deep reddish-purple flower color without requiring continued complex breeding operations
