Plapink 1004 Raspberry Breeding for Consistent Yield
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current raspberry varieties lack consistent and abundant fruit production across multiple seasons, with limited spine density and specific fruit color characteristics, making them less desirable for commercialization.
Innovation Solution
The development of the 'Plapink 1004' raspberry variety, which is a result of crossing two unpatented raspberry parents, exhibits a combination of traits such as medium spine density, abundant light red fruit production, and a unique greyed-green leaf underside color, distinguishing it from its parents and closest varieties like 'Adelita'.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If current raspberry varieties are used, then fruit production is limited and inconsistent, but increasing spine density and fruit production abundance would improve variety distinction and commercial value
Solution Approach 1:
The patent applies parameter changes by selectively breeding for specific quantitative traits including medium spine density (7-9 spines per cm), light red fruit color (RHS red group near 41 A to 42 A), and conical fruit shape. These parameter optimizations result in Plapink 1004 producing 1285.5g of fruit per plant from September to December, demonstrating improved productivity and consistent production reliability.
2Quantity of substance
If fruit production abundance is increased, then yield improves, but maintaining specific fruit color characteristics and quality becomes more challenging
Solution Approach 1:
The patent applies local quality by maintaining distinct fruit color characteristics (light red, RHS red group near 41 A to 42 A) and conical shape while achieving high yield. The variety produces 1285.5g of fruit per plant with consistent light red coloration, demonstrating that local quality traits can be preserved alongside increased quantity through targeted breeding.
3Reliability
If spine density is increased for variety distinction, then plant defense and identification improve, but excessive density may affect fruit production and plant vigor
Solution Approach 1:
The patent optimizes spine density to a medium range of 7-9 spines per cm, which provides sufficient variety distinction and plant defense without excessive density that would hinder fruit production. This optimized parameter setting allows Plapink 1004 to achieve high fruit yield of 1285.5g per plant while maintaining clear variety identification through spine characteristics.
