花生病毒病是花生的重要常发性流行病害,每年给花生生产带来很大损失。近年来我们鉴定了三种主要花生病毒:花生轻斑驳病毒(PMMV),黄瓜花叶病毒CA株系(CMV-CA)和花生矮化病毒Mi株系(PSV-Mi)。PMMV流行范围很广。CMV-CA和PSV-Mi在北方部分花生产区流行,常在田间和PMMV形成复合侵染。为了对病害经济重要性作出正确估计及为病害产量损失计算提供科学依据, Peanut virus disease is an important perennial epidemic disease, peanut production each year to bring great losses. In recent years, we identified three major peanut viruses: PMMV, CMV-CA and PSV-Mi. PMMV is very popular. CMV-CA and PSV-Mi are endemic to the northern part of the flowering area, often forming a composite infection with PMMV in the field. In order to correctly estimate the economic importance of the disease and provide a scientific basis for calculating the yield loss of the disease,
