A new strain of Capsicum chlorosis virus (CaCV) from peanut ( Arachis hypogaea L.) in China, designated CaCV‐CP, was characterized. CaCV‐CP causes yellow spots and necrosis on the leaves of affected peanut plants. Of 31 plant species inoculated mechanically, 24 were susceptible to this strain. Quasi‐spherical virions were present in ultrathin section of diseased leaves. The complete sequence of S RNA of CaCV‐CP consisted of 3399 nucleotides (nts). The NSs and N genes of the virus contained 1320 nts and 828 nts, respectively; these two open reading frames were in an ambisense arrangement. The N gene of CaCV‐CP shared 84.7–86.4% and 92.4–93.1% identity with that of CaCV strains from Thailand and Australia at nt and amino acid levels, respectively (the GenBank accession number of the sequence reported in this study is DQ355974 ).
