Studies on the Peanut Virus Disease in North China Ⅰ. Identification of Peanut Stunt Mosaic Disease in North China

１９８７～１９９３年期间，在河北、河南、山东、辽宁、北京４省１市先后采集花生矮花叶病及斑驳病标样２９０个，冷干保存，经用鉴别寄主测定、间接ＥＬＩＳＡ、电镜观察证明，引起北方花生产区花生矮花叶病的病原是花生条纹病毒（轻斑驳病毒）（ＰＳＴＶ原ＰＭＭＶ）、花生矮化病毒（ＰＳＶ）、花生黄瓜花叶病毒（ＣＭＶ—ＣＡ）、花生斑驳病毒（ＰＭＶ）其发生频率依次为４７％，４１．３％，３３．３％，３．３％．在我国除台湾省外，在北方花生产区第１次报道ＰＭＶ的发生。

samples of peanut with stunt mosaic symptoms were collected from four provinces and one city in North China. Samples were dried and brought to university in 1987～1993 year, and mechancally inoculated to chenopodium armaranticolor and other 6 hosts.The identification of pathogen of virus were determined by Symptomology. serology and electron microscopy. Peanut stunt mosaic virus disease Caused by pmmv(PSTV). psv-CMVCA. PMV. The incidence of disease is 47 %, 41. 3%, 33%, 3%, respectively. This is the first report of the occurence of PMV (peanut mottle virus)in North China.
