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。
Soil sorption technology was used to evaluate the resistance to sorghum smut in 150 sorghum germplasm resources (including sorghum CMS, maintainer and restorer) widely used in sorghum breeding in China. After two years’ repeated appraisal, 47 out of 150 sorghum germplasms were screened out, which represented 31.3% of the total number of IMs. The results of high resistance (HR) and moderate resistance (MR) ), Respectively, accounting for 4.0% of the total number of appraised materials; 4 for resistance (R), accounting for 2.7%; 13 for susceptibility (S), accounting for 8.7%; 74 for high sensitivity 49.3%. The above results show that the resistance to head smut is more abundant in breeding germplasm widely used in sorghum breeding.
