Part A
Please answer these questions true or false:
PERFORMANCE EVALUATION FOR CROP CULTIVAR RELEASE 433
References and suggested reading
Outcomes assessment
1 A breeder is required to register his or her cultivar upon release.
2 A non-crossover G × E interaction indicates a lack of differential performance.
3 Hybrids may not be registered.
Part B
Please answer the following questions:
1 Give the organization responsible for crop registration in the USA.
2 Give the purpose of a field trial in plant breeding.
3 Give the kinds of cross that can be registered.
4 Distinguish between the breeder’s trial and the official trial.
Variety protection
In addition to registration, a breeder may seek legal protection
of the cultivar in one or several ways as discussed
in detail in Chapter 15. A common protection, the Plant
Variety Protection, or the Plant Breeders’ Rights, is a
sui generi (of its kind) legal protection, as discussed.
