Abstract: The present paper deals with the main experimental results about the anther cul- ture in maize. Induction frequency varies with the different varieties and it is the highest when the excised anthers with the pollen grains at the middle-uninuclear stage are inoculated. Induction freguency of pollen embryoids or calli increases apparently when the medium is added with 500 mg/l casein hydrolysate, 0.5% active carbon and 15% sucrose. Four different pathways of androgenesis have been observed: Pathway of vegetative cell, pathway of generative cell, pathway of vegetative and generative cell in mixed development and pathway of equal division of the uninuclear pollen grain. All these pathway of development have been discussed.
