Solution Overview

Problem

Current strawberry cultivars lack resistance to Fusarium wilt and exhibit lower yields and fruit firmness compared to 'UC Eclipse', which also faces challenges in maintaining consistent flowering and fruit quality across varying day lengths.

Innovation Solution

The development of 'UC Eclipse', a day-neutral strawberry cultivar resulting from a cross between 'Portola' and 'UCD Mojo', which is resistant to Fusarium wilt, exhibits higher yields, firmer fruit, and consistent flowering across different day lengths, utilizing marker-assisted selection and asexual propagation to enhance genetic distinctness and disease resistance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional strawberry cultivars are used, then they are easier to cultivate, but they lack resistance to Fusarium wilt and exhibit lower yields

Engineering Contradiction:
Improvedisease resistanceVSAvoidyield
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent applies composite breeding by crossing two different strawberry cultivars ('Portola' and 'UCD Mojo') to create a new hybrid cultivar 'UC Eclipse' that combines disease resistance traits with high yield characteristics, effectively creating a composite genetic material that exhibits both desired properties simultaneously

Inventive Principle:
Principle #40Composite materials

2Strength

If parental varieties are used, then they have simpler genetic backgrounds, but they exhibit lower fruit firmness and yield compared to 'UC Eclipse'

Engineering Contradiction:
Improvefruit firmnessVSAvoidgenetic complexity
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

The patent applies local quality by selectively enhancing specific traits (fruit firmness, yield, disease resistance) in the hybrid cultivar while maintaining other desirable characteristics from the parental lines, achieving superior local properties without overwhelming genetic complexity

Inventive Principle:
Principle #3Local quality

3Adaptability or versatility

If day-length sensitive cultivars are used, then they may have simpler flowering control, but they cannot maintain consistent flowering across varying day lengths

Engineering Contradiction:
Improvephotoperiod insensitivityVSAvoidflowering consistency
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent applies universality by developing a day-neutral cultivar that can flower and produce fruit consistently across a wide range of day lengths and environmental conditions, making the cultivar universally adaptable to different growing seasons and geographic locations without requiring specific photoperiod control

Inventive Principle:
Principle #6Universality (Multi-functionality)
