Sorghum arundinaceum, a natural host of Peanut Clump Virus in Upper-Volta
#Sorghum arundinaceum# (great millet) was found as a symptomless natural host of Peanut Clump Virus (PCV) in Upper Volta. The PCV was characterized by mechanical transmission on #Chenopodium amaranticolor# and peanut, physical properties, electron microscope observations, and serology after purification from great millet leaves. Peanut clump disease has been observed in two countries only, Upper Volta and Senegal (3,6), which are 2 000 km apart. A study of Peanut Clump Virus (PCV), discovered in Upper Volta, enabled us to determine some of its physico-chemical characters and its serological properties, and to establish that it was a new two-components rod-shaped virus (5). PCV is soilborne (1), and the disease is recurrent on peanut in spite of a rotation of 6 years without that crop plant (M. Djigma, personal communication). We made a study to find which weeds or cultivated plants might be PCV hosts in contaminated fields. The present paper reports the results obtained and describes great millet (#Sorghum arundinaceum#) as a new natural host of PVC.
