Isi artikel

High incidence of pepper yellow leaf curl virus (Pep YLCV) was observed in indonesia since early 2000. Disease incidence in yogyakarta, central and est java reached 100% on capsium frutescens, but only 10-35% on c. annuum. As an exception, the disease incidence on c. annuum cv. TM 999 was in the range of 70-100%. The causal agent of the fisease, Pep YLCV, was detected by polymerase chain reaction. Viral specific DNA fragment of the size 1600 bp and -550 bp was amplified from infected plants using two pairs of geminivirus universal primers pAL1v1978/pALIc715 and pAv494/pAC 1048, respectively. The PepYLCV has an intermediate host range including plants belonging to the family of solanacease, leguminosae and compositar. the species belonging to the families of cucurbitacease, malvacease, chenopodiacease, and amaranthaceae were resistant to the virus. Physalis floridana is very prospective as a propagation host for the geminivirus infecting pepper. Nicotiana spp, cucumber, watermelo, cotton and sida sp could used as a differential host. Besides capsicum frutescens cv cakra, tomato, n, benthamiana, n, glutinosa and ageratum conyzoides could be used as indicator plants for the geminivirus infecting pepper.
