1. Male Sterility (MS) and Self-Incompatibility 1. Male Sterility (MS) 2. Self-Incompatibility (SI)
2. Types of Male Sterility and Self-Incompatibility Systems 1. Types of Male Sterility 2. Types of Self-Incompatibility
3. How MS and SI affect Reproduction in plant and correction of problems 1. Effect of MS in Reproduction 2. Effect of SI in Reproduction
4. MS and SI Effect/Use in Crop Breeding Exercise 1. Male Sterility in Plant Breeding 2. Self-Incompatibility in Crop Breeding

1. Introduction
Self-incompatibility (SI) and Male Sterility (MS) are widespread phenomena in flowering plants. It has however been suggested that in classifying plants according to why they may fail to set seed, that, it is desirable to distinguish between incompatibility and sterility. With Self-incompatibility there is restriction of breeding within populations and it seems to contribute through the establishment of unilateral barriers between self-incompatibility and self compatible populations. Male sterility on the other hand is characterized by non-functional gametes; caused by chromosomal aberration, genes action, etc
Two phenomena plays important roles in plant breeding; as plant breeders are often interested in modifying the breeding system in crop plants in order to substitute ether permanently or temporarily some mating system that serves their purpose better than the natural system of the species
In respect to this the purpose of this term paper is to review the importance of Male sterility and Self0incompatibility in crop improvement. This term paper shall however consider the various types of MS and SI; how they affect reproduction in plants;
