Blueberry Variety C14-409 Breeding for Early Cropping and Large Fruit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a blueberry variety that combines early cropping time, low chilling requirement, medium vigour, non-deciduous type, large fruit size, good fruit flavor, and firm fruit, which existing blueberry varieties have not adequately addressed.
Innovation Solution
The new blueberry variety 'C14-409' was developed through controlled breeding, combining traits such as evergreen, very early cropping, low chilling requirement, large fruit size, strong bloom, and small picking scar, achieved by crossing 'FL09-315' and 'FL07-285', and has been stably propagated through cuttings, maintaining its characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If a blueberry variety is selected for early cropping time, then the cropping time is improved, but the fruit size may be reduced
Solution Approach 1:
The patent applies parameter changes by selecting and breeding plants with specific genetic parameters that simultaneously achieve early cropping time and large fruit size. The variety 'C14-409' was selected from a population of seedlings based on multiple parameters including very early cropping time and large fruit size, demonstrating that parameter optimization through selective breeding can resolve this contradiction.
2Weight of stationary object
If a blueberry variety is selected for large fruit size, then the fruit size is improved, but the chilling requirement may increase
Solution Approach 1:
The patent uses parameter changes by identifying and selecting plants with optimized genetic parameters that achieve both large fruit size and low chilling requirement. The variety 'C14-409' exhibits average fruit weight of 3.3 g (large fruit size) and chilling requirement of only 0-300 hours (low chilling requirement), demonstrating successful parameter optimization through controlled breeding programs.
3Productivity
If a blueberry variety is selected for medium vigour, then the plant growth is controlled, but the yield may be reduced
Solution Approach 1:
The patent applies parameter changes by selecting plants with optimized vigour parameters that balance growth control and yield production. The variety 'C14-409' exhibits medium vigour with semi-upright growth habit and produces high yield of approximately 6.0 Kg per plant, demonstrating that parameter optimization can simultaneously achieve growth control and high productivity.
