Special rules of classification

A01H groups and subgroups are globally directed to tissue culture and classical breeding techniques and C12N 15/82 subgroups to transgenics. However the two are not mutually exclusive. For example traits which have been identified and used in transgenics may warrant classification in both areas, as may regeneration methods which are part of a transformation protocol.

Main groups A01H 5/00 through A01H 17/00 are only used for new, non-transgenic, plants (usually varieties)

Processes for modifying genotypes (A01H 4/00 takes precedence)
Definition statement

This place covers:

Breeding methods as further defined by the sub-groups.

Methods or apparatus for hybridisation; Artificial pollination
Definition statement

This place covers:

Inter alia creation of hybrids, crossing, sterility systems etc.; Appratus for pollination in A01H 1/025

Relationships with other classification places
Processes of selection
Definition statement

This place covers:

Inter alia marker assisted breeding.

Relationships with other classification places
Processes for producing mutations, e.g. treatment with chemicals or with radiation (mutation or genetic engineering C12N 15/00)
Definition statement

This place covers:

Inter alia altering repair and recombination sytems.

Relationships with other classification places
Methods or apparatus for producing changes in chromosome number
Definition statement

This place covers:

Inter alia creation of haploids, doubled haploids etc.
