Using genomics to improve fruit quality

New fruit varieties are needed to satisfy consumers, and the industry is facing new challenges in order to respond to these demands. The emergence of genomic tools is releasing information on polymorphisms that can be utilized to expedite breeding processes in species that are diffi cult to breed, given the long periods of time required to get new varieties. The present review describes the current stages of the ongoing eff orts that are being taken to apply these technologies to obtain varieties with improved fruit quality in species of the family Rosaceae. Key words: Polymorphisms, Marker Assited Selection, Genomic Tools. adapted to the local agronomic conditions and satisfy the requirements of the consumer have been carried out in the last 50 years. In recent years breeding programs have been dealing with increasing challenges, including the development of improved varieties for traits that have complex genetic control (quantitative traits). These programs must deliver results in the shortest possible time and they also need to be adapted to local agricultural climatic conditions. For a long time the breedin
