DrisBlueTwentyOne Blueberry Yield and Stability via Preliminary Action
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new, stable, high-yielding, and agronomically sound blueberry plant varieties that can thrive in various latitudes and produce medium to large, sweet-flavored fruit with specific characteristics such as elliptic leaves and dark blue mature fruit.
Innovation Solution
The development of the blueberry plant variety 'DrisBlueTwentyOne', which was created by crossing proprietary plants '136D 2' and '181C 1', exhibits elliptic leaf shape, light green unripe fruit color, and dark blue mature fruit, and is propagated via softwood cuttings, showing stability and high productivity with a mid-range chill hour requirement suitable for latitudes between 30 to 40 degrees.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If new blueberry varieties are developed through crossing, then fruit quality and yield are improved, but stability and true-to-type reproduction may be compromised
Solution Approach 1:
The patent performs preliminary testing over eleven years (2008-2019) through multiple asexual propagations via softwood cuttings to establish variety stability before commercial release. This preliminary action ensures that the new variety 'DrisBlueTwentyOne' reproduces true-to-type and maintains consistent characteristics, resolving the contradiction between improving yield through crossing and maintaining variety stability.
2Productivity
If blueberry varieties are bred for high yield, then productivity increases, but adaptability to various latitudes and chill hour requirements may be reduced
Solution Approach 1:
The patent creates a blueberry variety with localized optimal characteristics for specific geographic regions. 'DrisBlueTwentyOne' has a mid-range chill hour requirement specifically suited for latitudes between 30 to 40 degrees, allowing high productivity (8,000-12,000 kg/ha/season) in its target region without compromising adaptability to the intended growing conditions.
3Productivity
If fruit size is increased, then marketability and yield improve, but fruit firmness and sweetness may be compromised
Solution Approach 1:
The patent achieves optimal fruit parameters through controlled crossing and selection. 'DrisBlueTwentyOne' produces medium to large sized fruit that simultaneously maintains firmness and sweetness, resolving the contradiction between increasing fruit size for higher yield and preserving fruit quality attributes. The variety achieves 8,000-12,000 kg/ha/season yield with fruit that is both large and firm.
