  1. *The plants used for pathogenicity test. TP1, mustard (B. juncea var. megarrhiza Tsen et Lee) cv. Guangtou; TP2, Chinese kale (B. oleracea var. alboglabra) cv. Xianggangbaihua; TP3, cabbage (B. oleracea var. capitata) cultivar (cv.) Jingfeng-1; TP4, kohlrabi (B. oleracea var. gongylodes) cv. Chunqiu; TP5, pakchoi cabbage (B. rapa subsp. chinensis) cv. Jinchengteai; TP6, pakchoi cabbage (B. rapa subsp. chinensis) cv. Naibaicai; TP7, Chinese cabbage (B. rapa subsp. pekinensis) cv. Zhongbai-4; TP8, Chinese cabbage (B. rapa subsp. pekinensis) cv. Zhongbai-83; TP9, radish (R. sativus var. longipinnatus) cv. Huaye; TP10, radish (R. sativus var. radicula) cv. Manshenghong; TP11, radish (R. sativus var. sativus) cv. Cherry Belle. +, virulent; -, non-pathogenic; (+), weakly virulent. The hypersensitive reaction (HR) tests of Xcc strains were carried out on non-host plant pepper (Capsicum annuum v. latum) ECW10R (TP12). HR, positive HR result; N, no HR.
