摘　　要：茄子黄萎病是由大丽轮枝孢引起的一种土传病害,严重影响了茄子的产量和品质,选育和种植抗病品种是控制茄子黄萎病的经济有效措施之一。本文采用伤根接菌法对茄子品种资源进行了统一标准的抗黄萎病性鉴定。结果表明,茄子品种资源对黄萎病具有较好的抗病性,在35个参试的茄子品种中,属于抗黄萎病的有242-9OP、41-1和35-R5等10个,耐茄子黄萎病的有23个。通过鉴定评价,推荐了41-1、35-R5和47-R1等一批抗黄萎病资源,被育种单位利用后已转育出EF9910等抗病品种。Eggplant Verticillium wilt,caused by Verticillium dahliae,is one of the vascular bundle diseases and badly reduces the yield and quality. It was been proved that breeding and growing resistant cultivar was one of the economical and effective measures to control this disease. In this study, resistance of eggplant resources was evaluated by method of watering the injured roots with Verticillium dahliae spore suspension. Of 35 resources evaluated ,242-9OP,41-1,35-R5 and other 7 resources were resistant, and 23 resources were tolerant. The resistant resources such as 41-1,35-R5 and 47-R1 were recommended based on this evaluation,and the resistant eggplant cultivars such as EF9910 were obtained with these resistant resources employed in breeding practice.
