Experiment types, subtypes, and sub-subtypes

Experiment types
The EBS supports various kinds of experiments as given in the table below:
Experiment Type |
|
|---|---|
Breeding Trial | Experiments have a set of germplasm with or without checks and a statistical design and are conducted in a single location or multiple locations to compare the yield, disease response, physiological traits etc. of the selected germplasm |
Intentional Crossing Nursery | Parent roles and crosses to be made are predefined before planting. Different types of crosses such as single crosses, double crosses, three-way (top) crosses, back crosses, reciprocal crosses etc. can be included in the nurseries. |
Cross Parent Nursery | Parents are planted first without assigning parent roles. Parental combinations for crosses are determined after the initial experiment has been created and may include different types of crosses such as single crosses, double crosses, three-way (top) crosses, back crosses, etc. Delaying the cross planning may allow time to include additional phenotypic or/and genotypic data not available at the time of creating the nursery. |
Generation Nursery | Experiments are used for advancement and/or selection of segregating populations and for seed increases (multiplications). The germplasm is typically self-pollinated through natural or artificial means. |
Observation | Experiments are commonly used for screening nurseries or disease screening. The entries and checks may be replicated and planted according to the order specified by the user without using a statistical design. |
Experiment subtype
An experiment subtype refers to a specific category or variation within a broader experimental design or methodology. It helps further classify experiments based on particular characteristics or approaches used.
Sub-types of experiments can include the following
Controlled Experiments – Where data are collected in a controlled environment (greenhouse, laboratory, etc)
Examples: Disease screening, Genotyping, Grain Quality,
Field Experiments – Conducted outside the lab in real-world settings.
Examples: Yield Trial, Agronomic trial, Seed Increase
Experiment sub-subtype
Further provides a more specific description of the experiment subtype. For example, if the subtype is Disease Screening, the sub-subtype can be the actual disease (BPH, Blast, etc).
