A mediterranean japonica rice (Oryza sativa) cultivar improvement through anther culture.

Certified seed producers systematically select and propagate registered varieties year after year in order to maintain their uniformity and the original registered cultivar traits. However, natural mutations, spontaneous breeding between varieties and alien grain contamination can introduce undesir-...
