Calibrachoa Cultivar USCALI413-11 Breeding for Uniformity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Calibrachoa cultivars lack uniform plant habit and attractive flower characteristics, with variations in environmental conditions affecting phenotype and genotype stability.
Innovation Solution
Development of the new Calibrachoa cultivar 'USCALI413-11' through planned breeding, combining compact, mounding, and spreading growth habit with orange-colored flowers featuring red centers and venation, achieved through cross-pollination of proprietary seedling selections CJ04-23 and CJ04-22, and stabilized through asexual reproduction by terminal cuttings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If cross-pollination breeding is used to create new Calibrachoa cultivars, then flower color and plant habit diversity is improved, but phenotype stability under varying environmental conditions deteriorates
Solution Approach 1:
The patent applies parameter changes by selectively breeding for specific phenotypic parameters (flower color, plant habit) while maintaining genetic stability. The new cultivar USCALI413-11 exhibits consistent orange-colored flowers with red centers and venation, along with a compact mounding growth habit, across varying environmental conditions including temperatures from 7°C to 35°C. This resolves the contradiction by changing the phenotypic parameters to achieve both diversity and stability.
2Stability of the object's composition
If asexual reproduction by terminal cuttings is used, then genotype stability is improved, but propagation time and complexity increase
Solution Approach 1:
The patent applies preliminary action by performing terminal cutting propagation under controlled greenhouse conditions to establish stable genotypes before field deployment. The cutting process is optimized to take approximately three weeks to produce rooted young plants in summer and four weeks in winter at temperatures of 20°C. This preliminary propagation step ensures genotype stability is achieved before the plants are subjected to varying environmental conditions in the garden.
3Manufacturing precision
If compact mounding growth habit is selected, then plant uniformity is improved, but lateral branching complexity increases
Solution Approach 1:
The patent applies local quality by creating uniform compact mounding plants through controlled lateral branching. The new cultivar USCALI413-11 exhibits about eight primary lateral branches each with multiple secondary lateral branches, with pinching enhancing branching to achieve the desired compact form. This localized control of branching structure achieves plant uniformity while managing the inherent complexity of lateral branching patterns.
