Strawberry Cultivar FS 1705 Yield and Postharvest Longevity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current strawberry cultivars face challenges in achieving a balance of good fruit quality, ease of harvesting, high yield, and postharvest longevity, with existing varieties often compromising on one or more of these traits.
Innovation Solution
The development of the new strawberry cultivar 'FS 1705', resulting from a cross-pollination between Fragaria x ananassa 'Calinda' and a proprietary selection, exhibits a compact, upright growth habit, early and uniform fruit ripening, medium to large-sized conical fruits with a pleasant aroma and sweet taste, and excellent postharvest longevity, addressing the limitations of its parent varieties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional strawberry cultivars are grown to achieve high yield, then fruit quantity increases, but postharvest longevity deteriorates
Solution Approach 1:
The patent applies parameter changes by developing a new cultivar with modified genetic parameters that simultaneously improve both yield and postharvest longevity. The breeding program selected for specific traits including higher yielding capability combined with enhanced firmness and slower ripening characteristics, resulting in a cultivar that achieves both improved productivity and extended shelf life without the traditional trade-off
2Volume of moving object
If strawberry plants are bred for large fruit size, then fruit dimensions increase, but ease of harvesting deteriorates
Solution Approach 1:
The patent applies local quality by developing fruits with non-uniform firmness distribution - the calyx end maintains higher firmness for easier handling and harvesting, while the blossom end is softer for improved eating quality. This localized differentiation of mechanical properties allows large fruits to be easily harvested while maintaining consumer-desired softness in the edible portion
3Loss of time
If strawberry cultivars are selected for early fruit ripening, then time to market decreases, but fruit quality deteriorates
Solution Approach 1:
The patent applies dynamics by creating a cultivar with variable and extendable ripening periods. The strawberries exhibit a progressive ripening pattern where fruits can be harvested at different stages from early to late in the season, with quality maintained throughout. The cultivar's physiological characteristics allow extended ripening duration while preserving flavor, aroma, and texture qualities that are typically compromised in early-ripening varieties
