Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The need for self-compatible cacao clones to prevent monoclonal plantings that curtail yields and ensure successful pollination in areas where all clones are self-incompatible, particularly in regions like Indonesia.

Innovation Solution

Development of a new cacao plant variety, 'ISC-1', which is self-compatible and high yielding, originating from a controlled cross between 'MCC02' and 'RUQ1347', suitable for monoclonal plantations and asexually propagated via grafting.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If self-incompatible cacao clones are planted in monoclonal plantations, then planting simplicity is improved, but pollination success and yield are severely curtailed

Engineering Contradiction:

Improveplanting simplicityVSAvoidyield

Core Design Contradiction:

Ease of manufactureVSProductivity

Solution Approach 1:

The cacao clone ISC-1 is engineered to be self-compatible, enabling it to pollinate itself and produce seeds without requiring other compatible clones. This self-service capability allows monoclonal plantations to achieve both planting simplicity and successful pollination, resolving the contradiction between ease of plantation establishment and yield production

Inventive Principle:

Principle #25Self-service

2Reliability

If self-compatible cacao clones are developed, then pollination success is improved, but genetic diversity may be reduced

Engineering Contradiction:

Improvepollination successVSAvoidgenetic diversity

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The invention changes the compatibility parameter of the cacao clone through controlled breeding, transforming ISC-1 from self-incompatible to self-compatible. This parameter change enables reliable self-pollination while the clone maintains other desirable traits through careful selection in the breeding program

Inventive Principle:

Principle #35Parameter changes

3Ease of operation

If monoclonal plantations are established, then management simplicity is improved, but disease susceptibility increases

Engineering Contradiction:

Improvemanagement simplicityVSAvoiddisease susceptibility

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The self-compatible clone ISC-1 enables monoclonal plantations to function independently without requiring multiple clone varieties, simplifying management operations. The clone maintains good disease tolerance through its genetic characteristics, allowing monoclonal plantings to achieve both management simplicity and acceptable disease resistance

Inventive Principle:

Principle #25Self-service
