Cranberry NJS98-35 Breeding for Yield and Anthocyanin
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The cranberry industry faces challenges with a narrow genetic base and limited varieties, leading to reduced yields and anthocyanin content, as well as susceptibility to disease and environmental stresses, which affects productivity and fruit quality.
Innovation Solution
The development of a new cranberry variety, 'NJS98-35', resulting from crossing 'Franklin' and 'Ben Lear', which exhibits higher yields, increased anthocyanin content, and improved disease resistance, selected under stressful conditions in New Jersey.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a narrow genetic base of clonally-propagated varieties is used for cranberry production, then ease of cultivation and established farming practices are maintained, but productivity and anthocyanin content are reduced
Solution Approach 1:
The patent changes the genetic parameter of cranberry varieties by introducing new genetic combinations through controlled crossing of parent varieties 'Franklin' and 'Ben Lear', creating variety 'NJS98-35' with improved productivity and anthocyanin content while maintaining clonal propagation for ease of cultivation
Solution Approach 2:
The patent creates a composite genetic structure by combining traits from two distinct parent varieties ('Franklin' as seed parent and 'Ben Lear' as pollen parent) to produce a hybrid variety that exhibits superior yield and anthocyanin content compared to either parent alone
2Productivity
If older cranberry varieties selected from native populations are cultivated, then adaptability to local conditions is maintained, but yields and anthocyanin content are limited
Solution Approach 1:
The patent improves the productivity parameter by developing variety 'NJS98-35' with significantly higher yields and anthocyanin content through controlled breeding, while maintaining reliability through rigorous multi-year testing across different locations to ensure consistent performance
3Speed
If high stolon vigor varieties are planted to establish rapid growth, then bed establishment speed is improved, but transition to optimal sexual reproduction mode is delayed
Solution Approach 1:
The patent applies dynamics by balancing stolon vigor with upright density in variety 'NJS98-35', allowing rapid bed establishment followed by timely transition to optimal sexual reproduction mode, achieving both fast establishment and high crop production without the delayed transition seen in high-stolon-vigor varieties
4Reliability
If cranberry varieties are selected under low stress conditions, then ease of cultivation is maintained, but resistance to disease and environmental stresses is reduced
Solution Approach 1:
The patent applies preliminary anti-action by selecting and breeding variety 'NJS98-35' under high disease pressure and heat stress conditions in New Jersey, pre-adapting the variety to resist these stresses before commercial deployment, thereby reducing susceptibility to harmful factors while maintaining reliability

AI summary
A new cranberry variety distinguished by significantly higher yields, higher anthocyanin content (red pigment), lower titratable acidity, and larger fruit size. In addition, high TAcy values in September provide for an earlier harvest window for processed fruit, especially relative to ‘Stevens’ (unpatented), a primary commercial variety.
