Phlox Barphspribluimp Cultivar Breeding for Cold Tolerance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Phlox subulata cultivars lack attractive flower color and early flowering habits, and are not tolerant to low temperatures, limiting their garden performance and adaptability.
Innovation Solution
A new cultivar, 'Barphspribluimp', resulting from a controlled cross-pollination of proprietary Phlox subulata selections, exhibits a vigorous growth habit, upright and spreading plant habit, light violet blue flowers with darker centers, and improved low-temperature tolerance, distinguishing it from parent and similar cultivars like 'Emerald Cushion Blue'.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If existing Phlox subulata cultivars are used, then they are available for gardening, but they lack attractive flower color and early flowering habits
Solution Approach 1:
The patent applies parameter changes by systematically varying breeding parameters including selecting specific parent plants with desirable traits, controlling pollination timing, and selecting offspring with improved flower color intensity and earlier flowering habits. This resolved the contradiction by creating cultivars that maintain availability while significantly improving color attractiveness and flowering timing reliability
2Ease of manufacture
If existing Phlox subulata cultivars are used, then they are available for gardening, but they are not tolerant to low temperatures
Solution Approach 1:
The patent applied parameter changes by selecting parent plants with varying temperature tolerance characteristics, controlling breeding conditions to favor cold-hardy traits, and systematically evaluating offspring for low-temperature survival. This produced cultivars that maintain garden availability while significantly improving tolerance to freezing temperatures and cold weather conditions
3Reliability
If new cultivar 'Barphspribluimp' is developed through controlled cross-pollination, then attractive flower color and early flowering habits are achieved, but breeding program complexity increases
Solution Approach 1:
The patent applied segmentation by dividing the breeding program into distinct phases: parent selection, controlled pollination, seed propagation, and offspring evaluation. This systematic segmentation made the complex breeding process more manageable and reproducible, achieving reliable flower color and flowering timing improvements while organizing the complexity into standardized operational steps
