Studies on "Bunchy Top", "Chlorosis", and "Ring Mottle" Virus Diseases of Groundnut (Arachis hypogaea L.)

Groundnut Crinkle Virus, a New Member of the Carlavirus Group

“…Many viruses infect groundnut plants, but are different from groundnut crinkle disease. Some are not sap-transmissible: groundnut rmgspot (KUHN et al 1964), groundnut green rosette (KLESSER 1968), groundnut ring mottle (SHARMA 1966), groundnut mosaic (NARIANT andDHINGRA 1963, BERGMAN 1956), groundnut bunchy top (SHARMA 1966), groundnut witches' broom (BERGMAN 1956), groundnut marginal chlorosis (VAN VELSEN 1961) and groundnut rugose leaf curl (GRYLLS 1954, MONSARRAT 1976. Some diseases are sap-transmissible but have different particle morphology: groundnut eyespot (DUBERN andDOLLET 1978, 1980), groundnut rosette (OKUSANYA and WATSON 1966), peanut clump (THOUVENEL et aL 1976), tomato spotted wnlt (HELMS 1961), tobacco mosaic (NIAZI 1973), okra mosaic (GIVORD and HIRTH 1973), passionfruit woodiness (TAYLOR and GRABER 1973), and clitoria yellow vein (BOCK and GUTHRIE 1977).…”

Moreover, some sap-transmissible viruses have unknown particle morphology: groundnut chlorotic spot (HARAGOPAL and NAYUDU 1971), groundnut ringspot (KLESSER 1966), groundnut veinbanding (KLESSER 1967) and groundnut chlorosis (SHARMA 1966); all these diseases are different in their symptomatology, host range and in vitro properties, and are insect transmissible.…”

A New Sap Transmissible Groundnut Chlorotic Spot Virus

“…Peanut mottle virus produces local lesions on Cassia tora which is insusceptible to chlorotic spot virus. SHARMA (1966) reported a sap transmissible chlorosis virus bud did not report host range and properties. HEROLD and MUNZ (1969) described peanut mottle virus which is sap transmissible and it resembles the present virus in its method of transmission and producing systemic symptoms on soybean, mosaic in C. ensiformis and dilorotic spots on pea, but it differs in properties and producing local lesions on frenchbean variety.…”
