Resistance evaluation of eggplant resources to Verticillium wilt in Sichuan province.

[Objective] Aimed to lay a scientific foundation for eggplant resistant breeding,the resistant field identification of eggplant resources to Verticillium wilt was carried out.[Method] Test materials were 35 eggplant resources,which were collected from various places in Sichuan province since 2001.These eggplant resources were made resistance evaluation to Verticillium wilt by watering injured roots with Verticillium dahliae spore suspension.[Result] The eggplant resources had good resistance to Verticillium wilt.Among 35 evaluated resources,10 resources like 242-9OP,41-1,35-R5,etc.were resistant,while 23 resources like 68×47,Zizaoqie,32-1,etc.were tolerant.Some resistant resources like 41-1,35-R5,47-R1,etc.had been transferred into new resistant varieties like EF9910,etc.by breeding institutes.[Conclusion] The resistant level and future resistance breeding direction of eggplant resources in Sichuan were clarified by the resistance evaluation of eggplant resources so as to provide a technical guidance for eggplant resistance breeding.
