Begonia KRBEVPE02 Cultivar Breeding for Postproduction Longevity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new Begonia plant cultivars with improved post-production longevity and attractive flower color that can thrive under various environmental conditions while maintaining stable genetic traits through asexual reproduction.
Innovation Solution
The development of Begonia x hiemalis cultivar 'KRBEVPE02' through controlled breeding, combining traits such as upright to spreading plant habit, moderately vigorous growth, semi-double light orange and light red flowers, and excellent post-production longevity, achieved through cross-pollination of proprietary Begonia x tuberhybrida and Begonia socotrana selections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If cross-pollination breeding is conducted to create new Begonia cultivars with improved flower color and longevity, then the postproduction longevity and flower color are improved, but the breeding time and complexity increase
Solution Approach 1:
The patent applies preliminary action by conducting controlled cross-pollination breeding in advance to develop cultivars with predetermined improved traits. The breeding program was initiated beforehand to create 'KRBEVPE02' with enhanced postproduction longevity, allowing the cultivar to be ready for commercial production with these pre-established superior characteristics.
2Reliability
If cross-pollination breeding is conducted to create new Begonia cultivars with improved flower color and longevity, then the flower color and attractiveness are improved, but the breeding complexity increases
Solution Approach 1:
The patent applies feedback by implementing a controlled breeding program where the outcomes of cross-pollination are systematically evaluated. The inventor assessed the progeny for desired traits including flower color (light orange and light red), flower type (semi-double), and postproduction longevity, using this feedback to select and propagate the superior 'KRBEVPE02' cultivar.
3Productivity
If new Begonia cultivars are developed through breeding to achieve excellent postproduction longevity, then the commercial value is improved, but the manufacturing precision and trait stability requirements increase
Solution Approach 1:
The patent applies copying by using asexual reproduction methods to create genetically identical copies of the 'KRBEVPE02' cultivar. Through tissue culture and vegetative propagation, the inventor produced multiple plants that are true-to-type replicas, ensuring consistent inheritance of desirable traits such as semi-double flower type, light orange and light red coloration, and excellent postproduction longevity across commercial production.
