Abstract By spraying and root-dipping methods,this study carried out identification of resistance to black rot and Fusarium wilt on 99 cabbage accessions from domestic and overseas,including 83 inbred lines and 16 hybrid combinations.In total,26 accessions showed resistance to black rot,of which‘99-192’and‘20-2-5’with high resistance(DI < 10);54 accessions with high resistance to Fusarium wilt,including‘ Yin162’,‘Aoqina’and‘96-100-919’(DI < 10).Among them,5 accessions with high resistance or resistance to black rot+high resistance to Fusarium wilt.They were‘Qiude’,‘99-192’,‘HB34’,‘JS119’and‘ZL66’.‘JS119’and‘ZL66’were of early-maturity and round ball type.This study also conducted further analysis on the geographical origin and major agronomic traits of these resistant materials.The results showed that accessions highly resistant to Fusarium wilt out of 83 inbred lines were mostly originated from Japan and Korea and of earlymaturity and round ball type.While,accessions highly resistant to black rot were mostly of late maturity and spheroidicity.Among early maturing material,there were few accessions with stronger resistance to black rot.Genetic analysis on 16 hybrid combinations made up by different resistance showed that black rot and Fusarium wilt resistance was accorded with recessive and dominant inheritance,respectively.
