马铃薯是世界第四大粮食作物,其病毒病危害严重.2010年对湖南马铃薯主产区采集的66个病毒标样进行了RT-PCR检测,结果表明,检测出的马铃薯病毒有马铃薯Y病毒(PVY)、马铃薯卷叶病毒(PLRV)、马铃薯X病毒(PVX)、马铃薯S病毒(PVS)、马铃薯A病毒(PVA)和马铃薯纺锤块茎类病毒(PSTVd).其中PVS的检出率最高,为54.5%,其次是PVX ,检出率为45.5%, PVY的检出率为39.4%, PSTVd和PVA的检出率均为21.2%, PLRV的检出率为18.2%.2~4种病毒的复合侵染现象较为普遍. PVY中重组型PVY占85.7%.

Potato is the world＇s fourth major food crop. Potato virus disease is one of the most serious diseases and causes the yield loss. Sixty-six virus samples of potato collected from main potato areas of Hunan province were identified with RT-PCR in 2010. The results showed that 6 kinds of main potato virus （viroid） including PVY, PLRV, PVX, PVS, PVA and PSTVd were detected. Their proportions were 54.5 % （PVS）, 45.5 % （PVX）, 39.4 % （PVY）, 21.2 % （ PSTVd and PVA） and 18.2% （PLRV）, respectively. Moreover, 2-4 kinds of virus mixed infection were prevalent, among the ...
