摘　　要：采用土壤接种技术,对目前我国高粱育种上广泛应用的150份高粱种质资源(包括高粱不育系、保持系和恢复系)进行抗高粱丝黑穗病鉴定评价。经两年重复鉴定,在150份高粱种质中,筛选出对高粱丝黑穗病菌优势小种表现免疫(IM)的47份,占总数的31.3%;高抗(HR)和中抗(MR)的各6份,分别占鉴定材料总数4.0%;抗病(R)的4份,占2.7%;感病(S)的13份,占8.7%;高感(HS)的74份,占49.3%。上述结果表明,目前高粱育种中广泛应用的育种种质中抗丝黑穗病材料较为丰富。Using the soil inoculation technique,150 sorghum germplasm resources（ including male-sterile,maintainer and restorer lines） which used widely in sorghum breeding at present in China,were evaluated for resistance to sorghum head smut. Under two year identification,among 150 sorghum germplasm resources,there were 47 accessions of immune resources accounted for 31. 3% of the total. The highly resistant and moderately resistant of resources were each for 6 accessions with the tested germplasm resources proportion of 4. 0% respectively. The resistance resources were 4 accessions accounted for 2. 7 % of the total. The 13 accessions with susceptible and 74 accessions with highly susceptible resources were identified and it accounted for 8. 7% and 49. 3% of the total respectively. Based on the above data,there were relatively abundant resources with resistances to sorghum head smut in sorghum breeding.
