Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cranberry varieties face challenges in achieving high yield, disease tolerance, and consistent productivity, especially under stressful climate and soil conditions, with limited resistance to heat stress and fruit rot, and varying fruit quality for both processed and fresh markets.
Innovation Solution
The development of the cranberry variety 'CNJ99-9-25', derived from 'NJS98-23' and '#35', exhibits high yield potential, mid-season ripening, and adaptability to peat soils, with stable genetic reproduction and improved resistance to environmental stresses, meeting specific fruit quality criteria for both processed and fresh markets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If varieties with high stolon vigor are used to establish rapidly, then establishment speed is improved, but after stolon colonization, the transition to optimal sexual reproduction mode and upright density becomes difficult to achieve for high crop production
Solution Approach 1:
The patent applies parameter changes by selecting and breeding cranberry varieties with optimized genetic parameters that balance stolon vigor with upright density and sexual reproduction capacity. The variety CNJ99-9-25 was developed through controlled crosses (NJS98-23 x #35) to achieve specific genetic combinations that maintain rapid establishment while ensuring high crop production through optimal upright density and fruit set parameters.
2Productivity
If varieties are selected for high yield potential, then crop productivity is improved, but disease tolerance and resistance to environmental stresses such as heat stress and fruit rot become compromised
Solution Approach 1:
The patent applies composite materials by creating a composite genetic structure through crossbreeding. The variety CNJ99-9-25 combines desirable traits from parent varieties NJS98-23 and #35, integrating high yield potential with disease tolerance genes. This composite genetic makeup enables the variety to achieve both high productivity and reliability across multiple stress conditions including heat stress and fruit rot.
Solution Approach 2:
The patent applies local quality by developing varieties with specific localized adaptations to different growing conditions. The variety CNJ99-9-25 was particularly adapted to peat soils and moderate oceanic climates, with specific genetic traits that provide localized resistance to diseases and stresses prevalent in these environments while maintaining high yield potential.
3Loss of time
If varieties with mid-season ripening are developed, then harvest timing flexibility is improved, but fruit quality consistency for both processed and fresh markets becomes more difficult to maintain
Solution Approach 1:
The patent applies parameter changes by precisely controlling ripening parameters through selective breeding. The variety CNJ99-9-25 was developed with specific genetic parameters that achieve mid-season ripening while maintaining consistent fruit quality. The cross between NJS98-23 and #35 was selected to produce offspring with optimized anthocyanin content, acidity, and sugar content that remain consistent across mid-season harvests, satisfying both processed and fresh market requirements.
