Somatic Embryogenesis, In Vitro Selection and Plantlet Regeneration for Citrus Improvement

Citriculture is widely carried out in both tropical and subtropical regions and is one of the most economically important fruit crops. Although a high genetic variability is present in the genus Citrus and its wild relatives, improvement by conventional breeding is difficult because of the presence of nucellar embryos, a high degree of heterozygosity, and long juvenile periods, in addition to...
