Special rules of classification within this subclass

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 subclass/group covers:

Breeding methods as further defined by the sub-groups.

Methods or apparatus for hybridisation; Artificial pollination
Definition statement
This subclass/group covers:

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

Relationship between large subject matter areas
Processes of selection
Definition statement
This subclass/group covers:

Inter alia marker assisted breeding.

Relationship between large subject matter areas
Processes for producing mutations, e.g. treatment with chemicals or with radiation (mutation or genetic engineering C12N 15/00)
Definition statement
This subclass/group covers:

Inter alia altering repair and recombination sytems.

Relationship between large subject matter areas
Methods or apparatus for producing changes in chromosome number
Definition statement
This subclass/group covers:

Inter alia creation of haploids, doubled haploids etc.

Relationship between large subject matter areas
