Barley yellow dwarf virus (BYDV) was first reported in the northern Himalayan regions in 1963 and sporadic appearances have also been recorded in other parts of the Himalayas. However, the disease has never posed any serious threat to the wheat (Triticum aestivum L.) crop in this region. A very severe but extremely localized BYDV epidemic in the late 1970s at a research station in the Uttar Pradesh hills provided an opportunity to screen wheat germplasm for tolerance to BYDV and led to the identification on one resistant line NS 879/4. Systematic selection in crosses of NS 879/4, carried out during the epidemic year, led to the development of four
