摘要：
Ninety four cowpea germplasm accessions were evaluated tinder field conditions for viral infection, Virus disease incidence ranged from 0 to 66.6%. Based on ELISA and PCR results the following five viruses viz., cucumber Mosaic cucumovirus (CMV), bean common mosaic (BCMV), blackeye cowpea mosaic (BICMV) and cowpea aphid-borne mosaic potyviruses (CABMV) and mungbean yellow mosaic geminivirus (MYMV) were detected. Eighteen (19%), 45 (47.8%), 49 (52.1%) and 55 (58.5%) lines Out of 94 tested were found infected with CMV, BICMV, BCMV and CABMV, respectively. The natural Occurrence of BCMV, CMV and MYMV on cowpea are being reported for the first time in Pakistan. Ten accessions 27005, 29154, 27181, 27196, 27197, IT97K-89235, IT94K-556-6, IT96K-113-6. IT85F-1380 and IT95K-1985 were found resistant to viral infection.
