摘 要: | 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%。

Abstract: | 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 PVY samples,the proportion of recombinant PVY was 85.7%. |
