Abstract Changyang mountainous area is the main occurrence area for clubroot disease in Hubei
mountainous region. Taking 100 radish germplasm resources as material，this paper carried out clubroot resistance
identification during adult stage，and during seedling stage after artificial inoculation in the fields of Changyang
Hujiaping and Huoshaoping. According to the result of comprehensive resistance identification of adult and seedling
stages，13 resistant germplasm resources containing 8 white radishes（‘Fuyuan No.1’，‘Hualyu No.8’，
‘Chongqingbingtangyuanbai’，‘Chunbulao’，‘Yutangchun’，‘Hanbaiyu’，‘Chunyu’and‘Duanye No.13’），
3 red radishes（‘Hongguan’，‘Nanjinghong’and‘Dahongpao’）and 2 green radishes（‘Guantangqing’and‘Deri
No.2’）were screened out. In addition，155 radish hybrid combinations were identified in Changyang Huoshaoping
clubroot disease nursery and 3 good combinations resistant to clubroot were screened out.
