Abstract:Eighty seven accessions of cabbage(Brassica oleracea L.)breeding materials from different geographic origins were evaluated under 26-30 ℃ at the seedling stage for resistance to Fusarium wilt(Fusarium oxysporum f.sp.conglutinans)by using the most virulent isolate from Shanxi Province Shouyang county,named GLHW1,as the inoculum.Type A resistant gene was present in 36 accessions.31 of them were originated from Japan,Korea and some Europe countries,only 2 materials(C59 and C73)belong to traditional Chinese mainland breeding materials.The analysis on distribution of resistant gene in different cabbage populations showed that there were more resistant materials in round cabbage populations introduced from Japan and Korea,and in cabbage materials with grey-green leaves.There was rare resistant gene to Fusarium wilt in Chinese traditional earlymaturity cabbage.The high susceptible materials were amounted to 77.78 %.
