Viruses pose a serious threat to strawberry cultivation all over the world as infections resulting from viruses and related pathogens are limiting factors in the production of certified planting material in strawberry. In Himachal Pradesh, strawberry is fast emerging as a short duration fruit crop yielding lucrative returns. Viruses, however, have emerged as a major hindrance in its commercial cultivation. Direct antigen coating (DAC)-ELISA was performed in major commercial cultivars of strawberry to assess the presence of nematode transmitted nepoviruses in these cultivars as the infected plants developed typical ringspots on leaves, the most striking symptom of nepoviruses. DAC-ELISA resulted in the positive reaction against antibodies of nepoviruses thereby confirming the possible association of nepoviruses in the symptomatic plants. Further, double antibody sandwich (DAS)-ELISA was performed to identify the specific nepoviruses associated with infected strawberry plants. Results obtained in DAS-ELISA established the positive association in the three nepoviruses namely Strawberry Latent Ringspot Virus (SLRSV), Tobacco Ringspot Virus (TRSV) and Raspberry Ringspot Virus (RRSV) in the infected plants. These studies will help in the production of virus indexed planting material of strawberry for developing a sound certification programme in this commercially important crop.
