马铃薯病毒病是我省影响马铃薯生产的主要病害,在马铃薯栽培区广泛流行为害严重,特别在育种基地,病毒病类型更为复杂。如全国在会川保存的马铃薯品种资源近1000份,因病毒感染致使很多材料不结薯,不开花而失去使用价值,现仅剩300多份,还难以继续保存。为了弄清会川地区马铃薯病毒病种类,为抗病育种提供依据,我们按照全国马铃薯病毒病的协作计划,1982年用CMV、TMV、PVS、 PVX、 PVY、 TRV、 AMV等7种抗血清,对该地的马铃薯主要栽培品种、大田推广品种,以及区试品种进行了初步鉴定,现将结果总结
Potato virus disease is the main disease affecting potato production in our province. It is very harmful to the widespread epidemic in the potato cultivation area, especially in the breeding base. The virus disease type is more complicated. For example, there are nearly 1,000 potato varieties conserved in Huichuan in China. Because of the virus infection, many materials do not have potato tubers and do not bloom and lose their use value. Now there are only 300 remaining potatoes, and it is hard to keep them. In order to find out the types of potato virus diseases in Huichuang and provide the basis for the disease-resistant breeding, we used seven kinds of antisera such as CMV, TMV, PVS, PVX, PVY, TRV and AMV in 1982 according to the collaborative plan of the national potato virus disease, The main varieties of potato cultivation in this area, the promotion of varieties of the field, as well as the regional test varieties were initially identified, the results are summarized
