Androgenesis can be induced in tobacco and a few other species on a simple medium such as that developed by Nitsch and Nitsch (1969). For most other species, the commonly used media for anther culture include MS (Murashige and Skoog, 1962), N6 (Chu, 1978), or variations on these

This androgenesis pathway is also called microspore embryogenesis or regeneration. During androgenesis the haploid microspore divides and develops into an embryo and subsequently into a new haploid plant. Haploid plants are not fertile

Key words: androgenesis, cellular mechanisms, embryoids, genetic control, molecular and biochemical mechanisms, plant regeneration, somatic embryogenesis Abstract The inherent potential to produce plants from microspores or immature pollen exists naturally in many plant species.
Both androgenesis and tetraploidy are very dificult techniques to perform. It is hard to inactivate the DNA of the egg with UV light, and you must use toxic chemicals to accomplish this. Suppression of the irst cell division of the egg is also very dificult.
