Black Spot Disease

Black spot disease, which is caused by the Japanese pear pathotype of Alternaria alternata (Fr.) Keissler, is one of the most harmful diseases in Japanese pear cultivation. We identified the exact positions and linkage groups (LGs) of the genes for susceptibility to black spot in the Japanese pear ( Pyrus pyrifolia Nakai) cultivars ‘Osa Nijisseiki’ (gene Ani) and ‘Nansui’ (gene Ana). Segregation of susceptibility and resistance fitted the expected ratio of 1:1 in progeny of ‘Nansui’ but showed a slight distortion in progeny of ‘Osa Nijisseiki’. We mapped the genes for susceptibility to black spot in both populations using a genome scanning approach. The simple sequence repeat (SSR) markers CH04h02 and CH03d02 showed tight linkage to Ani and Ana. Although Ani and Ana are derived from different sources, both genes are located at the top region of LG 11. Information about the positions of the susceptibility genes and the molecular markers linked to them will be useful for marker-assisted selection in pear breeding programs.
