Nomenclature

Acronym

DoYMV

ICTV decimal code

29.0.3.0.015

Host range and symptoms

Natural host range and symptoms

Symptoms persist. Symptoms yellow or green mosaic with pitting.
• Lablab purpureus - yellow mosaic.

Transmission

Transmitted by a vector; an insect; Bemisia tabaci; Aleyrodidae. Transmitted in a semi-persistent manner. Virus retained when the vector moults; does not multiply in the vector; not transmitted congenitally to the progeny of the vector; not transmitted by mechanical inoculation; transmitted by grafting.

Geographical distribution

Spreads in India.

Experimental host range

Few (<3) families susceptible. Experimentally infected plants mostly show yellow mosaic.

Maintenance and propagation hosts

Lablab purpureus.

Assay hosts (Local lesions or Whole plants)
