| Abstract | Plant diseases are important factor in plant production. They reduce yield and lead to heavy use of chemicals to keep them under control. Genetic resistance is a potent alternative and environmental friendly disease control approach. One of the important tools used to establish genetic resistance of plant is DNA marker. The uses of DNA markers related to targeted agricultural traits, such as high productivity, resistance to disease andinsect, as tools for selection will improve the efficiency of plant breeding. Disease resistanceof plants can be divided into 2 types. Type 1 is complete resistance controlled by majorgene(s) such as Resistance gene (R gene). R gene plays an important role in the recognitionof gene products from the pathogen. Type 2 is partial resistance controlled by multipleminor genes, which is quantitative in characteristic. Pyramiding of major and minor genestogether is a strategy to develop durable resistance to meet the challenge that pathogensoften adapt and overcome genetic resistance. In this review, the information about the usesof DNA markers in plant breeding, major and minor genes responsible for plant diseaseresistance systems as well as strategies for establishing durable disease resistance ispresented. In addition, examples of marker-assisted selection in order to develop resistantvarieties for certain diseases in soybean, cassava and potato are presented. |
