Chabela Hybrid Squash Plant Yield and Disease Resistance

Solution Overview

Problem

There is a need for stable, high-yielding squash hybrids that excel in fruit production, appearance, and agronomic qualities, which existing squash breeding methods have not adequately addressed.

Innovation Solution

The development of the hybrid squash plant Chabela, which includes specific physiological and morphological characteristics, and methods for propagating and utilizing its seeds, fruits, and plant parts, including tissue culture and backcrossing techniques to introduce desired traits such as disease resistance and improved nutritional quality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If conventional squash breeding methods are used, then basic fruit production is achieved, but yield and agronomic qualities are insufficient

Engineering Contradiction:
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent applies preliminary action by developing and stabilizing parental lines (P1 and P2) with specific desirable traits before creating the hybrid. The parental lines are pre-selected for disease resistance, fruit quality, and agronomic performance, ensuring that the hybrid inherits stable and superior characteristics. This pre-preparation of parental material with defined traits resolves the contradiction by establishing a reliable genetic foundation before hybridization.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent employs composite materials by combining genetic material from two distinct parental lines (P1 and P2) to create a hybrid with composite traits. The hybrid squash Chabela integrates disease resistance from one parent, fruit quality attributes from another, and agronomic qualities from both, creating a composite genetic structure that simultaneously achieves high yield and stability.

Inventive Principle:
Principle #40Composite materials

2Productivity

If focus is placed on high yield, then fruit production increases, but fruit quality and appearance deteriorate

Engineering Contradiction:
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The patent applies local quality by assigning different functional traits to different parental lines. Parental line P1 is optimized for high fruit production and yield, while Parental line P2 is optimized for fruit quality, appearance, and eating qualities. The hybrid combines these locally optimized traits, allowing the final plant to simultaneously achieve high productivity and superior fruit appearance without compromising either attribute.

Inventive Principle:
Principle #3Local quality

3Reliability

If disease resistance is introduced through backcrossing, then resistance improves, but breeding complexity increases

Engineering Contradiction:
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies preliminary action by pre-selecting and stabilizing disease resistance traits in the parental lines before hybridization. Rather than introducing disease resistance through complex backcrossing after hybrid creation, the resistant traits are already established in Parental line P1 or P2. This preliminary incorporation of disease resistance simplifies the overall breeding process while maintaining high reliability of the trait in the final hybrid.

Inventive Principle:
Principle #10Preliminary action
