Petunia Dopetsuspare Cultivar Breeding for Compact Habit and Early Flowering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new compact, freely branching, and early-flowering Petunia plants with attractive flowers that offer improved garden performance and distinct flower colors, as existing varieties may lack these characteristics or have limited adaptability to environmental conditions.
Innovation Solution
A new Petunia cultivar, 'Dopetsuspare', resulting from a cross-pollination between proprietary selections of Petunia X hybrida, exhibiting a compact, upright to hanging habit, freely branching, and early flowering with large bright purplish red flowers featuring random white spots, demonstrating stability through asexual reproduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If existing Petunia varieties are used, then basic flowering is achieved, but compact growth habit and early flowering are not simultaneously achieved
Solution Approach 1:
The patent applies parameter changes by selecting and breeding plants with specific genetic parameters that control growth habit and flowering time. The cross-pollination between parent plants with desirable traits (compact growth, early flowering) produces offspring with optimized combinations of these parameters, achieving both compact habit and early flowering simultaneously.
2Adaptability or versatility
If traditional Petunia varieties are used, then flowering is achieved, but distinct flower color patterns are not obtained
Solution Approach 1:
The patent applies local quality by introducing specific color patterns (white spots on purplish-red flowers) through controlled cross-pollination. The breeding process selectively combines parental traits to create distinct local color characteristics in specific flower regions, achieving both color variation and consistent spot patterns across the cultivar.
3Productivity
If Petunia varieties with vigorous growth are selected, then plant size increases, but compact habit is lost
Solution Approach 1:
The patent applies dynamics by creating a balanced growth pattern where the plant exhibits compact overall size while maintaining vigorous local growth in flowering branches. The cultivar achieves this through selective breeding that promotes lateral branching and controls main stem elongation, allowing high flower production within a compact form.
