Conteúdo: | Embrapa Cassava and Tropical Fruits has many germplasm collections under field conditions to give support to breeding programs carried out there. These programs were focused just to the development of new materials for fresh fruit consumption or processing. A new approach has begun in 2002 looking for ornamental genotypes in these gene banks, mainly in the pineapple, banana, citrus and acerola collections. The identification, characterization and selection of potencial genotypes to be used as potted plants, cut flowers and landscape plants have been done. Initially, the morphological descriptors specific to each crop developed by IPGRI were adopted. Nevertheless, these descriptors are being adapted for use in the ornamental fruit crops aiming at cultivar protection and patenting. After the identification of interesting genotypes with ornamental potential, several controlled crosses were performed with pineapple, banana and citrus, resulting in the production of several promising hybrids. The resistance or tolerance against the most important diseases of these fruit crops have been considered in this work due to the economic importance they have in Brazil. Currently, new hybrids of pineapple, banana, citrus and some acerola genotypes identified in the gerplasm collection are under field and greenhouse evaluations, depending on their intended use. In addition, a very interesting and novelty product was also generated: the minifruits. These are small, non-edible fruits whose appearance is similar to the regular ones but destined to a differentiated marked.
