摘　　要：Viruses are considered the most important constraint to hot and sweet pepper (Capsicum sp.) production in China, from which nine virusesViruses are considered the most important constraint to hot and sweet pepper （Capsicum sp.） production in China, from which nine viruses have been reported （Wang X.P. et al., 2002）. However, so far no information has been available about the presence of begomoviruses in peppers. From 1999 to 2005, 762 leaf tissue samples were collected from farmers＇ fields in 13 provinces, namely Yunnan, Guangxi, Hainan, Guangdong and Guizhou in the south, Sichuan, Chongqing, Hunan, Jiangxi, Shaanxi and Henan in the central region, and Hebei and Heilongjiang in the north, and showed typical virus symptoms such as mottling, mosaic, yellowing and leaf deformations including leafcurling. Polymerase chain reaction with the degenerate primer pair PAL1 v 1978/PARlc 715 （M.R.Rojas et al., 1993） was used to test DNA extracts for the presence of begomoviruses. Leaf homogenates were tested by DAS-ELISA for the presence of other common chilli-infecting viruses such as Cucumber mosaic virus （CMV）, Chilli veinal mottle virus （ChiVMV）, Potato virus Y （PVY）, Tomato mosaic virus （ToMV）, Pepper mild mottle virus （PMMV） and Pepper veinal mottle virus （PVMV）, the latter reportedly known to occur throughout Africa （Dafalla G.A., 2003）.
