Attributes of Progeny Testing
Which of the following is true regarding Progeny testing-
- Increase generation interval
- Reduce genetic gain per year
- Estimates breeding value
- All the above — Correct Answer
Explanation:
Correct Answer: All the above
All three statements about Progeny Testing are correct:
- It increases generation interval because the sire must wait for progeny performance before being selected.
- It reduces genetic gain per year due to the longer generation interval (ΔG = Response / L).
- It estimates breeding value of a sire based on performance of its progeny.
Progeny Testing — Key Facts
| Feature | Detail |
|---|---|
| Basis | Performance of progeny |
| Primary use | Selection of Sire |
| Accuracy | Most accurate basis of selection |
| Best for | Traits with low heritability |
| Type | "Two-way selection system" |
| Disadvantage | Increases generation interval → reduces annual genetic gain |
| Used with ONBS? | No — Sibling test preferred (shorter generation interval) |
- Sibling test is less accurate than progeny testing but gives higher annual genetic gain due to shorter generation interval.
- ONBS (Open Nucleus Breeding Scheme) uses sibling test for faster genetic improvement.
