Abstract: By artificial inoculating Pear Scab, we found that Zaojinxiang pear showed high resistance to Pear Scab, which provide the basis for pear resistance breeding and resource utilization in the future. Also, its leaf tissue structure was studied, the result was that the palisade tissue was consisted of two layers and is very thick, the spongy parenchyma is tight, and the epidermis wax is thick, too. Therefore, we infer that these Characteristics determine the pear scab can’t invade into the leaves of Zaojinxiang easily, and they play a role in resisting pear scab. That provide theoretical basis for pear breeding in resistance of pear scab.
