This technical disclosure describes improvements that would be readily apparent to a Person Having Ordinary Skill In The Art (PHOSITA) when considered in combination with the foundational architecture disclosed in U.S. Patent No. 11,856,905.

Background and Problem Solved

The original patent, Canola hybrid 18GG0453L, presented a novel rapeseed variety with low erucic acid and glucosinolate content. However, the breeding process was time-consuming and inefficient. The new invention addresses these limitations by introducing a system for optimizing canola hybrid breeding, enabling faster and more targeted breeding programs.

Novelty and Inventive Step

The new invention provides a novel system for optimizing canola hybrid breeding, which is distinct from the original patent's focus on a specific rapeseed variety. The use of a database of genetic markers and a breeding program that incorporates recurrent selection and backcrossing provides a non-obvious solution to the problem of inefficient breeding programs.

Alternative Embodiments and Variations

Alternative embodiments of the invention could include the use of different breeding programs, such as doubled haploidy or mutation breeding, or the incorporation of additional genetic markers for other desirable traits. Variations of the invention could also include the application of the system to other crop species or the development of new software tools for data analysis and breeding decision support.

Potential Commercial Applications and Market

The invention has significant commercial potential in the canola industry, enabling faster and more targeted breeding programs that can improve crop yields and quality. The system could be marketed to canola breeding companies, research institutions, and government agencies, providing a competitive advantage in the development of new canola varieties.

▼

Field of Art

Plant Breeding and Genetics, specifically focused on canola (rapeseed) hybrid development, involving molecular marker-assisted breeding techniques and genetic trait optimization

Person of Ordinary Skill (PHOSITA) Profile

A plant geneticist or plant breeder with advanced degree in agricultural sciences, expertise in molecular breeding techniques, genetic marker identification, and hybrid development strategies, familiar with recurrent selection and backcrossing methodologies

Obviousness Rationale

A PHOSITA would recognize that the PTD's disclosed breeding system represents a predictable extension of the source patent's hybrid development approach, utilizing standard molecular breeding techniques to optimize canola trait selection. The systematic approach of identifying genetic markers, implementing marker-assisted selection, and applying established breeding programs represents an incremental improvement consistent with standard agricultural genetic research practices. The variations proposed are logical progressions of existing breeding methodologies that would be apparent to a skilled practitioner seeking to enhance hybrid development efficiency.
