Petunia Duegpwi Breeding for Compact Habit and Early Flowering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new semi-upright to trailing Petunia plants with unique and attractive flowers that offer improved compact growth habits and early flowering capabilities, as existing cultivars may lack these desirable traits.
Innovation Solution
A new cultivar of Petunia×hybrida, designated 'Duegpwi', was developed through cross-pollination, exhibiting a compact, semi-upright to trailing growth habit, freely branching, and large white-colored flowers, which are stable and reproduce true to type through asexual reproduction by terminal cuttings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If existing Petunia cultivars are used, then they may have upright growth habit, but they lack compactness and early flowering capabilities
Solution Approach 1:
The patent applies parameter changes by selectively breeding Petunia plants to modify growth habit parameters (from upright to compact semi-upright) and flowering time parameters (to achieve early and continuous flowering). This is accomplished through controlled cross-pollination and selection of plants exhibiting desirable parameter combinations.
2Ease of operation
If Petunia plants are bred for compact growth habit, then they may lose flowering productivity or attractiveness
Solution Approach 1:
The patent applies local quality by creating plants with differentiated regional characteristics: compact overall plant habit combined with large flower size and continuous flowering capability. The plant exhibits localized compactness in foliage and stem structure while maintaining localized abundance in flower production.
3Productivity
If Petunia plants are bred for large flower size, then they may lose compact growth habit or trailing characteristics
Solution Approach 1:
The patent applies segmentation by separating the plant into distinct functional zones: compact trailing vegetative growth (stems and leaves) and large flowering structures. This allows the plant to exhibit compact overall habit while producing large flowers as separate prominent features.
