Celery Cultivar TBG 39 Bolting Tolerance Breeding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Celery cultivars face challenges such as bolting, disease susceptibility, and market defects due to seed stems, which affect yield and quality, and existing breeding methods struggle with synchronizing vernalization and pollination processes.
Innovation Solution
Development of the celery cultivar TBG 39, which includes specific morphological and physiological traits like bolting tolerance, disease resistance, and improved agronomic qualities, achieved through advanced breeding techniques like backcrossing, genetic marker enhanced selection, and transformation, enabling the production of stable, high-yielding celery plants.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If celery is transplanted early to extend growing season and increase yield, then productivity improves, but vernalization occurs causing bolting and market defects
Solution Approach 1:
The patent applies parameter changes by selecting and breeding celery varieties with modified vernalization requirements. Specifically, the invention identifies and utilizes genetic variations that allow celery to tolerate extended cold exposure without bolting, changing the physiological parameters of vernalization sensitivity and bolting threshold to enable early transplanting without the harmful bolting effect
2Reliability
If celery varieties with high bolting tolerance are selected, then reliability improves, but the length of growing season is limited
Solution Approach 1:
The patent changes the physiological parameters of celery varieties through selective breeding to achieve both high bolting tolerance and extended growing season capability. The invention identifies genetic markers and breeding lines that have fundamentally altered their vernalization response, allowing them to accumulate cold exposure units without triggering bolting, thereby extending the safe transplanting window and growing season duration
3Device complexity
If conventional breeding methods are used, then device complexity is low, but synchronization of vernalization and pollination is difficult
Solution Approach 1:
The patent applies feedback principles by using bolting incidence as a measurable indicator to monitor and adjust breeding programs. The method involves tracking bolting rates in different varieties under controlled vernalization conditions, using this feedback information to select parent lines with desired traits, and iteratively improving the breeding strategy based on observed synchronization outcomes between vernalization and pollination events
