Citrus is one of the world’s prime fruit crops having great economic and health value. Citrus genetic improvement is impeded by barriers to sexual hybridization like nucellar embryony, long juvenility, self incompatibility and hybrid nature of important cultivated species. Further there is risk of destruction by diseases threatening to the citrus production and future availability for human consumption. Recently rapid technological advances made in citrus cell and tissue culture techniques, ploidy manipulation, genetic transformations, genome mapping and quickly adapted to mitigate the challenges to citrus biology. The classical areas of tissue culture regeneration pathways are micrografting for disease free planting material, nucellar embryogenesis for uniform rootstock seedlings (micropropagation), production of haploids and seedless citrus triploids through somatic embryogenesis for will open vistas for citrus genetics breeding and cultivar improvement. In this status report/ review the current state of various aspects of citrus biotechnology was reviewed and future strategies / application are speculated.
