Experiment Types

 

The EBS supports various kinds of experiments as given in the table below:

Experiment Type

 

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.
