Anthurium Plant Breeding for Durable Spathes and Continuous Flowering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new variety of Anthurium andraeanum L. with specific characteristics such as weakly blistered and medium glossy, green, cordate spathes, white spadices with green tips, dark green, medium glossy, ovate-cordate leaves, and a unique spathe position relative to the leaves, which are durable and consistent across generations.
Innovation Solution
A new variety, 'AN2429660', was developed through a breeding program in Bleiswijk, Netherlands, by crossing '18374-04' and '21958-07', and reproduced via tissue culture, exhibiting the desired traits including upright growth habit, specific leaf and spathe characteristics, and continuous flowering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional breeding methods are used to develop new Anthurium varieties, then genetic diversity is improved, but breeding time and complexity increase significantly
Solution Approach 1:
The patent applies preliminary action by conducting multiple cross-pollination experiments in advance (2010-2012) to establish suitable parental combinations before selecting the final variety. The breeder pre-screened parental plants for desired traits (spath e durability, color, shape) and performed preliminary crosses to identify promising progeny lines, thereby reducing the overall breeding timeline while maintaining genetic diversity exploration.
Solution Approach 2:
The patent employs copying through asexual reproduction via tissue culture to propagate the selected variety 'AN2429660'. Once the ideal genotype was identified through breeding, it was cloned multiple times to produce identical copies, preserving the specific combination of traits (weakly blistered spathes, green color, cordate shape, durability) without requiring continued sexual breeding.
2Manufacturing precision
If selective breeding is performed to achieve specific spathe characteristics, then spathe quality is improved, but the complexity of the breeding program increases
Solution Approach 1:
The patent applies local quality by focusing selection criteria on specific local characteristics of the spathe rather than requiring excellence in all traits. The breeder targeted specific attributes: weakly blistered surface texture, green coloration, cordate (heart-shaped) form, and enhanced durability. By concentrating on these particular local qualities rather than overall plant performance, the breeding program achieved precise spathe quality improvement with manageable complexity.
Solution Approach 2:
The patent employs parameter changes by systematically varying breeding parameters including parental plant selection criteria, pollination timing, and environmental conditions during flowering. The breeder adjusted these parameters across multiple breeding cycles (2010-2014) to optimize the expression of desired spathe characteristics in the progeny, thereby improving spathe quality while managing program complexity through controlled parameter modification.
3Stability of the object's composition
If multiple breeding cycles are conducted to stabilize traits, then trait consistency is improved, but the duration of the breeding program increases
Solution Approach 1:
The patent applies feedback by systematically evaluating progeny plants against the target trait profile after each breeding cycle and using this information to guide subsequent breeding decisions. The breeder assessed spathe characteristics (blistering, color, shape, durability) in the 2014 progeny selection, compared results to desired outcomes, and adjusted the breeding approach accordingly to stabilize the trait combination more efficiently across generations.
Solution Approach 2:
The patent employs this principle by using temporary parental plants and early-generation progeny as disposable materials in the breeding process. Less ideal parental plants or progeny that did not meet the target criteria were discarded and replaced in subsequent crosses, allowing the breeder to quickly eliminate unsuccessful trait combinations without investing excessive time in stabilizing them, thereby reducing overall program duration while achieving trait consistency in the final variety.
