Abstract

This chapter broadly covers the modes of reproduction in crop plants. The knowledge of the reproductive biology, life cycle, and type of cultivars are important for plant breeders to develop appropriate breeding strategies. Information on sexual and asexual modes of reproduction and propagation in crop plants are covered. The chapter contains concepts on mechanisms that promote self-fertilization and cross-fertilization, as well as genetic consequences of self- and cross-fertilization. Details on male sterility (cytoplasmic, genetic, and cytoplasmic–genetic male sterility) and maintenance of these genetic materials are included. Concepts and manipulation of self-incompatibility (heteromorphic and homomorphic—gametophytic and sporophytic) are described and their applications in plant breeding are provided. This chapter establishes the foundation of competency in familiarity of crop plants.
