Velluto Blue Rabbiteye Blueberry Yield and Quality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing blueberry varieties lack desirable traits such as larger fruit size, higher Brix levels, improved plant vigour, later fruit flowering, and higher yields, which are essential for enhanced agricultural productivity and consumer appeal.
Innovation Solution
The development of the 'Velluto Blue' blueberry variety, which is a result of crossing 'Maru' and 'Briteblue', exhibiting larger oblate fruit, higher Brix levels, greater plant vigour, later fruit flowering, and higher yields, along with resistance to certain diseases and pests, and suitable for medium to late harvest seasons.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If existing blueberry varieties are used, then cultivation is straightforward, but fruit size, Brix level, plant vigour, and yield remain suboptimal
Solution Approach 1:
The patent applies parameter changes by crossing two parent varieties with different genetic parameters to produce offspring with improved characteristics. The F128 plant exhibits changed parameters including larger fruit size (14-18mm diameter), higher Brix levels (12-15%), greater plant vigour, and higher yields compared to parent varieties, while maintaining adaptability through stable inheritance of these improved traits
2Volume of moving object
If blueberry varieties with larger fruit size are selected, then consumer appeal increases, but harvest timing and disease resistance may be compromised
Solution Approach 1:
The patent applies composite materials principle by combining genetic traits from two parent varieties ('Maru' and 'Briteblue') to create a composite genotype in F128. This genetic composite provides both large fruit size (14-18mm diameter, oblate shape) and disease resistance through the combined genetic heritage, including resistance to common blueberry diseases while maintaining the desired fruit characteristics
3Loss of time
If early harvest varieties are planted, then market timing is optimized, but fruit quality and Brix level may be reduced
Solution Approach 1:
The patent applies dynamics principle by providing growers with flexibility in harvest timing through a variety that maintains high fruit quality across different harvest windows. The F128 variety produces fruit with consistent high quality characteristics (12-15% Brix, large size, oblate shape) whether harvested in medium or late season, allowing optimization of harvest time based on market conditions without sacrificing fruit quality

AI summary
A new and distinct rabbiteye blueberry variety is described. The variety results from selection among a population of seedlings derived from the controlled crossing of the blueberry varieties ‘Maru’ (not patented) and ‘Briteblue’ (not patented). The fruit of this new variety has an attractive appearance characterised by outstanding fruit quality with a good bloom and little grittiness, and medium to late fruiting season. The new variety appears suitable for the medium to late fresh fruit market and has been named ‘Velluto Blue’.
