| Abstract: | A virus, first reported from China in 1983 as producing a mild mottle in groundnut, was further characterized and named peanut stripe potyvirus (PStV) in the USA. It has since been reported from major groundnut-growing areas in south-east Asia including India, and has been found to cause economically significant crop losses. Besides groundnut, it infects soyabean, cowpea, Indigofera amoena, Pueraria phaseoloides, Stylosanthes capitata and S. craba naturally. The virus is seedborne and transmissible mechanically by sap and by Aphis craccivora. The movement of infected seed has resulted in its wide dissemination. Serologically, the virus is closely related to blackeye cowpea mosaic potyvirus (BLCMV), Azuki bean mosaic potyvirus (AzMV) [blackeye cowpea mosaic potyvirus] and the serogroup B strains of bean common mosaic potyvirus (BCMV), and distantly to clover yellow vein potyvirus and soybean mosaic potyviruses. PStV was initially described as a new virus, but recent molecular studies have shown that it is a strain of BCMV which also includes BLCMV, AzMV and 3 potyvirus isolates from soyabean. No genotype of cultivated groundnut is resistant to PStV. However, several wild genotypes of groundnut are immune or highly resistant to the virus, and it is suggested that they could be used in future breeding programmes. It is concluded that the most efficient means of containing the virus at present is the use of virus-free seed |
