Fruit tree breeding has to face numerous constraints which strongly slow down development and release of new varieties. The breeding methods are often empirical, as a result of the low genetic knowledge on the main agronomic traits, to which is added the influence of environment. Thus, breeders are looking for new methods to speed up selection process to release new cultivars. In the last ten years, significant development have been made in molecular biology applied to perennial crops in particular in genetic mapping of major genes and QTLs. This technical improvement makes it possible to develop a new approach: the marker assisted breeding or MAB. It is based on the researches from upstream and on the techniques allowing the high throughput genotyping of large numbers of individuals. It is already exploited for traits showing simple heredity in several fruit breeding programs, in particular in peach tree. Even if it is less obvious and more complex to implement on quantitative inherited traits, it is a real improvement compared to traditional breeding methods. MAB thus appears a promising approach to fruit tree breeding
