Petunia DANRAY5 Cultivar Breeding for Mounded Habit and Red Flowers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new Petunia cultivar with a mounded plant habit and large, uniquely colored inflorescences that can thrive in various environments and maintain its characteristics through asexual reproduction.
Innovation Solution
The development of the Petunia cultivar 'DANRAY5' through controlled breeding, combining traits such as a mounded growth habit, large red flowers, high floriferousness, early blooming, and long bloom period, achieved by crossing Petunia sensu Wijsman 'PE-1705' and 'PE-99', which is propagated via vegetative cuttings and demonstrates stability across generations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If Petunia sensu Wijsman 'PE-1705' and 'PE-99' are crossed to create a new cultivar, then unique flower coloration and mounded growth habit are achieved, but the complexity of breeding program increases
Solution Approach 1:
The breeding program is segmented into controlled crosses between specific parent lines ('PE-1705' and 'PE-99') with defined objectives, allowing systematic development of desired traits (mounded habit and unique coloration) while managing complexity through structured approach
2Reliability
If vegetative cuttings are used for propagation, then true-to-type reproduction is achieved, but the time required for propagation increases
Solution Approach 1:
The cultivar 'DANRAY5' is designed to reproduce true-to-type through vegetative cuttings, where the plant's own genetic characteristics are preserved and propagated without external intervention, ensuring reliability while the process is optimized for timing
3Shape
If large inflorescence with unique coloration is developed, then aesthetic value increases, but the plant size and space requirements increase
Solution Approach 1:
The cultivar concentrates large inflorescence with unique red and white coloration at specific locations (flower clusters) while maintaining compact mounded growth habit, allowing aesthetic prominence without proportional increase in overall plant space requirements
