Production and Uses of Haploids Introduction
Haploids are defined as sporophytes with gametophytic number and have been produced in a variety of plant species using a variety of methods. Although, the significance of haploids in genetics and plant breeding has been recognized for long time, it has received renewed emphasis with the advent of new biotechnology, so that the production of haploids has become an important component of biotechnology programmes in different countries.

Although, haploids could be produced following delayed pollination, irradiation of pollen, temperature shocks, colchicines treatment and distant hybridization, the most important methods currently being utilized under biotechnology programmes include (i) anther or pollen culture and ovule culture and (ii) chromosome elimination following interspecific hybridization (bulbosum technique). These techniques for production of haploids and the uses of haploids in genetics and plant breeding will be discussed in this chapter.
