The production of large numbers of haploid plants from pollen grains in aseptic culture of anthers or isolated pollen grains has now been demonstrated in many angiosperms. It is a technique which holds much promise for creating desired variability by mutations for biochemical and applied genetics and for producing pure lines for crop improvement. This paper reviews the research on the production of haploids from pollen grains. The response is dependent on a variety of factors such as media formulation (especially the hormone component), genotype and physiological status of the donor plant, developmental stage of the pollen grain, anther culture environment and anther wall itself - all of which influence greatly the successful production of haploid plants. Although still in its infancy, the culture of isolated pollen is seen as a promising line of further research as it has the potential of offering several advantages over the culture of whole anthers. |
