The wheat cultivar, Dera 98, coded as DW-2, was first tested at Agricultural Research Institute, D.I.Khan in 1991-92 in 5th Warmer Areas Wheat Screening Nursery along with some others. Selected entries were advanced to preliminary yield trials and advanced yield trial because of their high yield potential, disease and heat resistance and acceptable stature as compared to three check varieties Pirsabak 85, Pirsabak 91 and Inquilab 91. Best performing entry, DW-2 was promoted to micro plot yield trial in 1995-96. DW-2 produced grain yield of 3799 kg ha-1 versus 3382 Kg ha-1 of Bakhtawar 92. This selection was further evaluated for yield, disease and heat resistance and other agronomic traits in National Uniform Wheat Yield Trials coordinated by National Agricultural Research Center, Islamabad on more than 22 sites during 1996-97 and on 30 sites during 1997-98 in Pakistan. Because of higher grain yield, disease and heat resistance and better grain quality, this entry was named as DERA 98 and was approved for general cultivation in southern N.W.F.P.
