Evaluation of Resistance to Bacterial Spot in Varieties Growing in China and Marker-assisted Selection

doi:10.7668/hbnxb.2009.04.036

Abstract

Abstract: There is little study on bacterial spot of tomato in China. The status of resistance to the disease in main cultivars is not clear.Thus, strains of races T1 and T3 of tomato bacterial spot were used to inoculate 39 varieties currently growing in China.Molecular markers were also used to analyze these varieties and to conduct marker-assisted selection. The results indicated that all varieties couldn't have hypersensit ive reactions to races T1 and T3 though some varieties had the same alleles as resistant varieties. Resistant lines were obtained by selecting lines from progenies derived from crosses between 9 susceptible varieties and resistant variety OH9834 using the marker tightly linked to the resistance locus Rx3. This study indicated that there was a lack of resistance in varieties growing in China and marker-assisted select ion could be used in developing varieties for resistance to bacterial spot in tomato.

Key words: Solanum lycopersicum, Bacterial spot, Resistance evaluation, Marker-assisted selection
