5 Introductionto reproduction Purpose and expected outcomes
ОглавлениеRudolph Camerarius is credited with establishing sexual differentiation, noting that male and female sex organs exist in the Plant Kingdom. Some species produce flowers while others do not. In flowering species, reproduction involves the union of gametes, following pollination. Plant breeders need to understand the mode of reproduction in order to manipulate plants effectively to develop new and improved ones for crop production. After studying this chapter, the student should be able to:
1 Discuss the importance of the mode of reproduction to plant breeding.
2 Distinguish between self‐pollination and cross‐pollination.
3 Discuss the natural barriers that favor or hinder each of the modes of reproduction.
4 Discuss the implications of mode of reproduction in schemes and strategies employed in plant breeding.
5 Discuss the use of male sterility and self‐incompatibility in breeding.
6 Discuss the natural mechanisms that favor allogamy.
7 Discuss the genetic consequences of allogamy.
8 Discuss the implications of allogamy in crop improvement.
