Caladium PSY LAV 2322-566B Breeding for Disease Tolerance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge is to develop a new Caladium plant cultivar with uniform plant habit, exceptional container and garden performance, and unique leaf coloration, while also providing tolerance to environmental variations and specific diseases like Xanthomonas Leaf Spot.
Innovation Solution
The cultivar 'PSY LAV 2322-566B' is bred from a cross between Caladium×hortulanum 'Carolyn Whorton' and 'Gingerland', exhibiting a compact, upright growth habit, lavender pink leaves with red purple venation, and above-average tolerance to Xanthomonas Leaf Spot, achieved through asexual reproduction by 'chipping' tubers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a new Caladium cultivar is developed through cross-pollination to achieve unique leaf coloration and uniform plant habit, then the aesthetic quality and plant form are improved, but the breeding time and complexity increase
Solution Approach 1:
The inventor performed preliminary cross-pollination breeding work in April 2010 between Caladium×hortulanum 'Carolyn Whorton' and 'Gingerland' to pre-establish the genetic foundation for the desired uniform mounded habit and leaf coloration traits before formal cultivar development and selection processes
2Adaptability or versatility
If the Caladium plant is bred for exceptional container and garden performance, then the adaptability to different environments is improved, but the breeding complexity and resource requirements increase
Solution Approach 1:
The breeding program targeted specific local quality traits including tolerance to Xanthomonas leaf spot disease, adaptability to container growth conditions, and performance in garden environments, developing these characteristics selectively in the Caladium×hortulanum cultivar through controlled cross-pollination and selection
3Productivity
If the Caladium plant is selected for rapid growth rate, then the productivity is improved, but the plant may become less compact
Solution Approach 1:
The inventor selected and bred for specific parameter combinations in the Caladium×hortulanum cultivar that simultaneously achieve rapid growth rate and compact mounded habit, adjusting the balance between growth speed and plant form through controlled cross-pollination between 'Carolyn Whorton' and 'Gingerland' and subsequent selection of superior progeny
