Somatic hybridization of Citrus for rootstock and Scion improvement. Development of new triploid mandarin hybrid varieties by fecundation of unreduced female gametes. Construction of the Bacterial Artificial Chromosome library to clone the gene for resistance to citrus tristeza virus quick decline. Somaclonal variation and general tissue culture of citrus.

Produced several interspecific and intergeneric allotetraploid somatic hybrids, even between sexually incompatible varieties. Many of the new hybrids are already in field trials; some of them are very promising as new rootstocks. Developed a new screening procedure (not published) to obtain triploid mandarin varieties for seedlessness that allowed the production of more than 2,000 new hybrids in less than 1/3 of the normal time required by other methods.
