Early embryo achievement through isolated microspore culture in Citrus clementina Hort. ex Tan., cvs. 'Monreal Rosso' and 'Nules'.

Microspore embryogenesis is a method of achieving complete homozygosity from plants. It is particularly useful for woody species, like Citrus, characterized by long juvenility, a high degree of heterozygosity and often self-incompatibility. Anther culture is currently the method of choice for microspore embryogenesis in many crops.
