SAN RAFAEL Raspberry Yield and Cold Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing raspberry varieties face challenges in yield, cold tolerance, post-harvest storage, and shelf life, with 'Tulameen' and 'Malling Exploit' showing lower yields and poor cold storage characteristics, and 'Glen Lyon' having smaller fruit and less favorable organoleptic qualities compared to 'SAN RAFAEL'.
Innovation Solution
The 'SAN RAFAEL' raspberry variety, developed through controlled breeding, exhibits higher yields, improved cold tolerance, larger fruit size, better post-harvest storage, and enhanced shelf life, characterized by its conical-elongated shape, firmness, and excellent taste and aroma, achieved through asexual propagation and tissue culture methods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If existing raspberry varieties like 'Tulameen' and 'Malling Exploit' are used, then cultivation is straightforward, but yield is lower and cold storage characteristics are poor
Solution Approach 1:
The patent applies parameter changes by developing a new raspberry variety with fundamentally improved physiological parameters - higher yield (39 tons/ha vs lower yields of parent varieties) and superior cold storage characteristics with extended shelf life up to 10 days at room temperature and 21 days in cold storage, resolving the contradiction between productivity and storage reliability
2Volume of moving object
If 'Glen Lyon' variety is used, then cultivation is established, but fruit size is smaller and organoleptic qualities are less favorable
Solution Approach 1:
The patent achieves parameter changes by creating fruit with superior dimensions (3.0-3.5 cm length, 2.0-2.5 cm width, 4.0-5.0 g weight) and enhanced organoleptic qualities including excellent taste, aroma, and firmness, significantly outperforming 'Glen Lyon' and resolving the contradiction between fruit size and quality precision
3Volume of moving object
If 'Malling Exploit' is used, then thorny protection is provided, but fruit size is smaller and post-harvest storage is poor
Solution Approach 1:
The patent implements parameter changes by producing fruit with larger size (4.0-5.0 g average weight vs smaller parent varieties) and dramatically extended shelf life (up to 10 days at room temperature and 21 days in cold storage), resolving the contradiction between fruit volume and storage duration
4Productivity
If 'Tulameen' is used, then fruit production is achieved, but cold temperature tolerance is insufficient
Solution Approach 1:
The patent applies parameter changes by developing a variety with high yield (39 tons/ha) combined with superior cold hardiness, able to tolerate temperatures down to -34.4°C and maintain productivity in cold climates, resolving the contradiction between productivity and cold temperature resistance
