摘要：

Pear scab caused by Venturia nashicola is one of the most destructive diseases of pears.Molecular markers linked to scab resistance gene is expected to be useful for improving pear.In this study,the F1 population derived from the cross of 'Huangguan' and 'Yali' was analyzed genetically.The resistance of pear to scab was proved to be controlled by a single gene in a dominant manner.Bulked segregant analysis(BSA) was conducted to screen 64 fluorescent AFLP primer pairs.A marker designated as D3-365 was found to be linked to the resistant locus.Selective genotype linkage analysis showed that the genetic distance between the marker and the resistant locus was 14.9 cM.
