Definition
| Self-pollinated w/o hybrid. Grow row out of one plant. Harvest superior, and create new rows out of each plant. |

Definition
| Self-pollinated w/o hybrid. Select from population for a certain trait in order to improve average performance. |
|
|
Term
|
Definition
| Self-pollinated w/ hybrid. Plants are separated into family plots. All crosses and traits are recorded. Labor intensive. |
|
|
Term
|
Definition
| Succeeding populations are bulked and grown, selection delayed until advanced generation. Low labor/cost. Self-pollinated |
|
|
Term
|
Definition
| One seed is harvested per plant for the first generations, selection delayed until later generation. Can be grown densely in greenhouse. Relatively fast. Self-pollinated |
|

Term
|
Definition
| Anthers are cultured into haploid plants, then doubled via colchicine. Time is minimal, but a reliable method for doubling is required.Self-pollinated |
|
|
Term
|
Definition
| A type of inbreeding used to change one gene in an otherwise desirable genotype. Self-pollinated |
|
|
Term
|
Definition
| Recurrent parents paired with parents containing various resistances to a pathogen. Only effective for high-risk pathogens. Labor intensive. Self-pollinated |
|
|
Term
|
Definition
| Seeds are harvested from desired plants without progeny testing. |
|
|
Term
| Half-Sib Progeny Test Selection |
|
Definition
| Plants grown in rows, remnant seed retained. Superior progeny are selected, and then the next generation is either parents of superior progeny or superior progeny. Requires plants that create many seeds per pollination. |
|
|
Term
| Half-Sib Testcross Selection |
|
Definition
| Seed from source crossed with tester plant, and either OP or selfed. New seed is reconstituted from remnant seed or selfed seed. |
|
|
Term
|
Definition
| Specific pairs crossed, and progeny tested. Seed composited from remnant seed of parents with successful progeny. |
|
|
Term
|
Definition
| Like full-sib, but plants are selfed for progeny test. |
|
|
Term
| Polycross Progeny Selection |
|
Definition
| Designed to have plants receiving equal exposure to all other clones. For synthetic cultivars. |
