Petunia Dopetsuspabl 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 characteristics, as existing varieties may lack vigor, branching, and unique flower patterns.
Innovation Solution
A new cultivar of Petunia X hybrida, 'DOPETSUSPABL', was developed through controlled cross-pollination, exhibiting a compact, upright to hanging habit, moderately vigorous growth, freely branching, and large violet flowers with random white spots, differing from parent selections in flower color and leaf characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional Petunia varieties are used, then existing varieties may lack vigor and branching, but they also lack unique flower patterns and attractive characteristics
Solution Approach 1:
The patent applies parameter changes by selecting and breeding plants with specific genetic parameters that result in improved growth habits. The new cultivar exhibits modified parameters including compact plant size (15-25 cm diameter), increased branching frequency, and enhanced flower production (5-15 flowers per plant), resolving the contradiction between garden performance and vigor/branching characteristics
Solution Approach 2:
The patent creates a composite genetic structure by cross-breeding different Petunia hybrids to combine desirable traits. The new cultivar 'Supa Blue' integrates characteristics from multiple parent lines, combining compact growth habit with vigorous branching and unique blue flowers with white spots, thereby achieving both adaptability and vigor simultaneously
2Volume of moving object
If Petunia plants are bred for compact size, then plant habit becomes manageable, but flowering time may be delayed
Solution Approach 1:
The patent uses parameter changes to achieve early flowering in compact plants by selecting for specific growth rate parameters. The new cultivar maintains a compact size (15-25 cm diameter) while exhibiting accelerated development parameters that result in flowering within 10-14 weeks from planting, eliminating the trade-off between size and flowering time
Solution Approach 2:
The patent applies preliminary action through controlled greenhouse propagation and rooting treatments before field planting. Cuttings are rooted in controlled environments with optimized temperature and humidity, establishing vigorous root systems in advance that enable rapid growth and early flowering once planted, thus achieving both compact size and early flowering
3Loss of time
If Petunia plants are bred for early flowering, then market readiness is improved, but flower size and attractiveness may be reduced
Solution Approach 1:
The patent applies parameter changes by selecting for independent genetic parameters controlling flowering time and flower size. The new cultivar achieves early flowering (10-14 weeks) while simultaneously developing large flowers (5-8 cm diameter) with unique blue coloration and white spotting patterns, breaking the traditional trade-off between these parameters
Solution Approach 2:
The patent applies local quality by enhancing specific floral characteristics while maintaining overall compact plant size. The flowers exhibit unique local features including blue petals with distinctive white spots concentrated in specific patterns, and a flared corolla shape, providing high visual impact despite the plant's compact dimensions
