Wheat (Triticum aestivum L.) is the major staple grain food of Pakistan and is prone to many pathological diseases especially viral diseases are among the biotic factors inflicting huge economic losses. Every year Barley yellow dwarf virus (BYDV) causes substantial losses to wheat crop. In this study, during survey 2013-14, a total of 210 samples examined from different wheat growing areas of Pakistan, 180 samples showing typical barley yellow dwarf viral symptoms following (90) yellowing tip Yt, (45) stunted growth St, (32) reddening Rd and (13) showed curling Cr. The symptom based indexing study can play an important role in the identification of BYDV and further epidemiological studies.
