Ipomoea Fnpalblk Cultivar Compact Habit and Branching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new compact and freely branching Ipomoea cultivars with attractive foliage shape and coloration that can reproduce true to type and exhibit enhanced branching and density compared to existing varieties.
Innovation Solution
The development of the Ipomoea batatas cultivar 'Fnpalblk' through cross-pollination between 'Sweet Caroline Bronze' and 'Sweet Caroline Purple', resulting in a compact, upright, and bushy plant with dark purple-colored palmate-shaped leaves, which is stable and reproduces consistently via terminal cuttings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If existing Ipomoea cultivars are used, then they have established foliage color and shape, but they lack compactness and free branching
Solution Approach 1:
The patent applies parameter changes by modifying the plant's growth parameters through controlled cross-pollination between specific parent varieties. The breeding process altered the plant habit parameters to achieve compactness while maintaining free branching, resulting in a new cultivar with optimized structural characteristics that differ from the parental forms.
2Productivity
If new cultivars are developed through cross-pollination, then improved branching and density are achieved, but stability across generations must be ensured
Solution Approach 1:
The patent applies preliminary action by conducting controlled cross-pollination under regulated environmental conditions and selecting specific parent varieties with known characteristics. This preliminary breeding action ensures that the desired traits for branching and density are established before mass propagation, facilitating stable inheritance in subsequent generations through asexual reproduction.
3Adaptability or versatility
If phenotypic variation occurs due to environmental factors, then adaptability is improved, but genotype consistency must be maintained
Solution Approach 1:
The patent applies self-service by utilizing asexual reproduction through terminal cuttings, allowing the plant to propagate itself while maintaining genotypic consistency. This self-propagation method ensures that the genotype remains pure and stable across generations, while the plant's phenotype can naturally adapt to different environmental conditions without genetic variation.
