摘　　要：In this paper,the identification,screening and evaluation of resistance in partial tomato cultivars of Sichuan Province were carried out in natural disease nursery so as to provide a scientific basis for the breeding of disease-resistant cultivars.The result showed most of the tomato cultivars had certain resistance to main diseases.Some tomato cultivars even had resistance to 2-3 kinds of diseases simultaneously.The tested tomato cultivars showed the highest resistance to Fusarium wilt,and 73.33% of the tested cultivars were resistant.In terms of Botrytis cinerea,40.00% of the tomato cultivars are resistant and 50.00% of the tomato cultivars are tolerant.Most of the tomato cultivars are moderately resistant to late blight.However,tomato cultivars are generally susceptible to viral disease.The viral disease-resistant tomato cultivars only accounted for 13.33% of the total cultivars.该文采用自然病圃,开展了四川省部分番茄材料的抗病性鉴定筛选评价,为选育抗病品种提供科学依据。结果表明,大多数番茄材料对主要病害均表现出一定的抗病性,部分材料对2-3种主要病害具有兼抗性。供试材料对番茄枯萎病的抗性最好,抗枯萎病材料占73.33%;对灰霉病,番茄材料多表现为耐病,抗灰霉病占40.00%,耐灰霉病的占50.00%;对晚疫病多表现为中抗;对番茄病毒病的抗性略差,抗病毒病的材料仅占13.33%。
