Solution Overview

Problem

Current melon breeding techniques have not fully addressed the need for new varieties with improved traits such as extended shelf life, disease resistance, and enhanced fruit quality, which are essential for farmers and consumers.

Innovation Solution

The development of melon variety NUN 76307 MEM, which features a Cantaloupe non-sutured type with extended shelf life, specific morphological and physiological characteristics, and resistance to certain diseases, achieved through selective breeding and genetic stability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If traditional breeding techniques are used to develop melon varieties, then genetic diversity can be maintained, but the development of uniform varieties with specific desirable traits is slow and inefficient

Engineering Contradiction:

Improvebreeding efficiencyVSAvoidvariety uniformity

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The patent applies preliminary action by developing homozygous inbred parent lines through multiple generations of self-pollination before crossing. This preliminary inbreeding ensures genetic uniformity and stability in the parent lines, which then produces uniform hybrid F1 progeny with consistent desirable traits, resolving the contradiction between breeding efficiency and variety uniformity.

Inventive Principle:

Principle #10Preliminary action

2Reliability

If self-pollination is used to develop homozygous inbred plants, then uniform true-breeding progeny are produced, but genetic diversity is reduced

Engineering Contradiction:

Improveprogeny uniformityVSAvoidgenetic diversity

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent merges the genetic material of two different homozygous inbred parent lines through cross-pollination. This combining of genetically diverse parent lines produces hybrid F1 progeny that exhibit heterosis (hybrid vigor), maintaining genetic diversity while achieving uniformity and reliability in the resulting variety through the consistent expression of hybrid traits.

Inventive Principle:

Principle #5Merging (Combining)

3Adaptability or versatility

If cross-pollination between different genotypes is used, then genetic diversity is increased, but the resulting progeny population becomes non-uniform and performance unpredictable

Engineering Contradiction:

Improvegenetic diversityVSAvoidprogeny uniformity

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent applies local quality by ensuring that the parent lines used for cross-pollination are themselves genetically uniform and homozygous at almost all gene loci. This localized uniformity in the parents ensures that while genetic diversity is introduced through crossing, the F1 progeny remain uniform and predictable in performance, resolving the contradiction between genetic diversity and progeny uniformity.

Inventive Principle:

Principle #3Local quality
