Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing blackberry varieties lack desirable traits such as thornless stems, high fruit yield, long shelf life, and resistance to common diseases, making them unsuitable for commercial fresh fruit markets.
Innovation Solution
Development of the 'MEF-2022.1' blackberry variety through cross-pollination, characterized by thornless stems, strong canes, large fruit, high vigor, easy harvesting, and resistance to common blackberry diseases, achieved through asexual reproduction and selection in a controlled environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional blackberry varieties are used, then they have thorned stems for natural protection, but they cause difficulty in harvesting and reduced productivity
Solution Approach 1:
The invention extracts and removes the thorns from the blackberry plant through selective breeding, eliminating the harmful protective feature while maintaining the plant's ability to protect itself through other means. The selected plant 'MEF-2022.1' naturally lacks thorns on its stems, allowing easy harvesting without the negative effects of thorny stems.
2Productivity
If conventional blackberry varieties are used, then they have smaller fruit size, but they require more plants to achieve high fruit yield
Solution Approach 1:
The invention combines multiple desirable traits into a single blackberry variety: large fruit size (13-16 grams), high vigor, thornless stems, and disease resistance. By merging these characteristics in one plant, the variety achieves both high productivity and large fruit size simultaneously, eliminating the need for more plants to compensate for small fruit size.
3Duration of action of stationary object
If conventional blackberry varieties are used, then they have shorter shelf life, but they require faster harvest and distribution
Solution Approach 1:
The invention performs preliminary selection and breeding to establish inherent shelf life characteristics in the plant variety before commercial production. The selected plant 'MEF-2022.1' has been pre-selected for long shelf life and vigorous growth, allowing it to maintain quality for extended periods after harvest without requiring accelerated harvest and distribution schedules.
4Reliability
If conventional blackberry varieties are used, then they are susceptible to common diseases, but they require more intensive disease management
Solution Approach 1:
The invention enables the blackberry plant to protect itself against common diseases through inherent resistance traits selected during breeding. The variety 'MEF-2022.1' has been selected for high tolerance to common blackberry diseases, allowing it to resist pathogens without requiring intensive external disease management interventions.
