Читать книгу Principles of Plant Genetics and Breeding - George Acquaah - Страница 142

Most of the traits that plant breeders are interested in are quantitatively inherited. It is important to understand the genetics that underlie the behavior of these traits in order to develop effective approaches for manipulating them. After studying this chapter, the student should be able to:

1 Define quantitative genetics and distinguish it from population genetics.

2 Distinguish between qualitative traits and quantitative traits.

3 Discuss polygenic inheritance.

4 Discuss gene action.

5 Discuss the variance components of quantitative traits.

6 Discuss the concept of heritability of traits.

7 Discuss selection and define the “breeders’ equation.”

8 Discuss the concept of general worth of a plant.

9 Discuss combining ability.
