Breeding Stage

Plant breeding involves selecting and crossing plants to create new varieties with desirable traits. The process generally follows several stages to achieve a desired outcome. A stage in EBS is one cycle of planting, and a cycle is 1 season.

Defining a breeding stage requires an abbreviation, name, and a description. The abbreviation can be part of automating the name of an experiment. ie. PR-HB-2025-WS-001, HB here is an abbreviation of Hybridization block.

A breeding stage can be classified according to the experiment types in EBS. Here are the examples.

1

Intentional Crossing Nursery and Cross Parent Nurseries

where there is an interaction of 2 biological materials

  • Hybridization

  • Crossing Block

  • Y1 recombinant block

  • Y2 Formation of test cross progenies

  • F1 nursery

  • Hybrid source nursery

  • Hybrid seed production

  • CMS Production,

  • BC1 First Backcross

  • BC2 2nd Backcross … (BC18)

  • Plant transformation

2

Generation Nursery

  • F1 Filial Generation 1

  • F2 Filial Generation 2 … (Fn)

  • BC1F2…(BCFn)

  • Test Cross verification

  • Seed Increase

3

Breeding Trial

  • Stage 1

  • Stage 2

  • Multi-location trial

  • Advanced yield trial

  • On Farmer’s Trial

4

Observation

  • Breeders Seed Production

  • Agronomic Trial

  • Pest screening

  • Disease screening

 

Pipeline

A pipeline, is a set of goals (i.e., breeding targets), or parameters that a stage is a part of. Typically, this is dictated by the institute and can be general or specific. An example is the list of breeding pipelines in IRRI, which can be seen here.

 

Project

A project is a planned and systematic effort to selectively breed plants or animals to achieve specific desired traits or characteristics in future generations.
