Rosa BLZ Calla Lily Cultivar Multi-Inflorescence Production
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new cultivar of calla lily that retains distinctive characteristics such as intense red-purple spathe color and medium-density leaf maculation, while producing multiple inflorescences, which existing cultivars lack.
Innovation Solution
A new cultivar 'Rosa BLZ' of Zantedeschia spp. is developed through asexual micropropagation, combining a red-purple spathe female parent and a pink spathe male parent, resulting in a plant with enhanced characteristics like taller habit, more inflorescences, and specific leaf shapes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If existing calla lily cultivars are used, then they have simple leaf patterns and single inflorescence production, but they lack intense red-purple spathe color and medium-density leaf maculation
Solution Approach 1:
The patent combines multiple desirable traits from different parental lines into a single cultivar. The female parent contributes red-purple spathe color while the male parent contributes pink spathe color and other characteristics, merging these traits along with medium-density leaf maculation and multi-inflorescence production into the unified 'Rosa BLZ' cultivar through controlled hybridization and micropropagation
2Stability of the object's composition
If asexual micropropagation is used to reproduce the cultivar, then distinctive characteristics are retained consistently, but the development process requires extended breeding time and controlled conditions
Solution Approach 1:
The patent performs preliminary hybridization between selected parental lines to create the desired genotype before large-scale propagation. The controlled cross-breeding between female parent (red-purple spathe) and male parent (pink spathe) is completed in advance, allowing the resulting 'Rosa BLZ' cultivar to be propagated asexually through micropropagation, thereby preserving the distinctive characteristics while establishing genetic stability before commercial production

AI summary
A calla lily plant particularly distinguished by a red-purple spathe with darker red-purple veins, medium density maculation of the leaves that is visible from both sides and which produces 2 to 3 inflorescences per 3-cm tuber, is described.
