Experiment Type | |
|---|---|
Breeding Trial | Experiments have a set of germplasm with or without check checks and a statistical design and are conducted in a single location or multi-location multiple locations to compare the yieldsyield, disease response, physiological traits etc. of the selected germplasm |
Intentional Crossing Nursery | Parent roles and crosses to be made are predefined before planting and make any type . 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 | Parent Parents are planted first without assigning parent roles, consider phenotyping or/and genotyping observations (results) to select parents and assign the parent roles before/at flowering time to make any desirable types of crosses |
Generation Nursery | Self-pollination occurs naturally and used for selection and advancement of segregating populations and seed increase (multiplications) of any selected lines or populations |
Observation | Experiments have small plots . 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. |
