Marker-Assisted Selection in Determining of Resistant Varieties against Plant Diseases in the Breeding Process

Abstract

In recent years, the new fighting methods against plant diseases that cause important crop losses have been developed. These methods are more practical, economic and healthy. Pesticides are widely used for fighting against the disease, but it is not an environmentally friendly method. Recently, it has been preferred to use resistant varieties in the organic farming. The purpose of resistance breeding is to detect resistance genes, transfer to cultivar plants, and clone. But the development of new varieties in classical breeding requires a long process. The using of molecular markers in the breeding process are more advantage over the other selection techniques and widely preferred today. In this study, it was investigated and compared the disease control methods used against to common bunt disease in Turkey and the World. We aimed to reveal the advantages and disadvantages of classical and molecular-based selection techniques in the breeding studies. Marker-assisted selection (MAS) includes the molecular-based techniques and is the relatively a new approach method to solve problems of classical breeding techniques. In this study, the importance of using classical breeding and molecular techniques together has been emphasized.
