Tissue culture in cherimoya.

The cherimoya is a species with a high degree of heterozygosis, which militates against propagation by seed. Traditional methods of vegetative propagation are inefficient, due to the low morphogenic potential of cherimoya, especially in terms of rooting. In vitro tissue culture techniques have been used to micropropagate cherimoya, cv. Fino de Jete, which is the major cultivar in Spain. After developing methodologies to micropropagate juvenile material, a protocol for the micropropagation of adult cherimoya plants was optimized. A breeding programme is currently being developed for cherimoya, which focuses on several in vitro methodologies. This includes somatic embryogenesis, adventitious organogenesis and cellular cultures, ploidy manipulation of the cherimoya to obtain haploid, tetraploid and triploid plants (seedless), autotrophy induction and genetic transformation to control postharvest processes and provide resistance to a number of pests and diseases.
