Description An ELISA procedure was developed to test groundnut seeds for Indian peanut clump furovirus (IPCV). A double antibody sandwich form of ELISA detected the Hyderabad isolate (IPCV-H) in seed of groundnut. Correlation was established between the results from ELISA performed on cotyledons of groundnut seed and grow-out tests. Seed transmission in the field-infected groundnut plants ranged from 3.5 to 17%, depending on the genotype. The transmission frequency was 48 to 55% in seed collected from plants infected through seed. Because testas of all seed contained viral antigen, their removal was essential for the determination of frequency of seed transmission. Apparently the virus present only in cotyledons and embryo contributed to the seed transmission. For the first time, IPCV-H was shown to be seed transmitted in finger millet (Eleusine coracana), foxtail millet (Setaria italica) and pearl millet (Pennisetum glaucum) at frequencies of 5.2, 9.7 and 0.9%, respectively. Seed transmission was not observed in sorghum. The significance of seed transmission in millet crops is discussed.
