Abstract:: Six walnut cultivars such as ‘Liaoning No.1’ were selected as test materials，position，disease level and morbidity of low-temperature sunburn and rot disease were measured and analyzed.The results showed that walnut rot disease mainly occurred in the south or southwest of the branches of the mature fruit trees，and the incidence of canker was accompanied by sunburn.There were significant differences in the resistance among different walnut cultivars，and which had low incidence of sunburn also had low incidence of rot disease；but the incidence and level of disease were not necessarily linked；the injury of rot disease and low-temperature sunburn was closely related.
