Abstract
Classical breeding programs have been carried out by several research teams all over the world to obtain apple cultivars resistant to scab, the most important disease of apple, without obtaining satisfactory marketable results. Recently, breeding techniques have been flanked by biotechnology. After cloning a gene (HcrVf2) linked to scab resistance from a wild Malus species, the sequence was introgressed with genetic transformation into a popular apple cultivar susceptible to scab. Some transgenic lines resistant to apple scab were obtained and evaluated. The results reveal that HcrVf2 gene is able to confer scab resistance to a susceptible cultivar
