Longmai 479 is a new winter wheat cultivar， bred by using pedigree method for directional selection in water and drought， with combination of Changwu 134 as the female parent and TW98-829-1 as the male parent. In 2017 — 2019， the average yield was 5 235.00 kg/hm2， 13.6% higher than that of the control Longyu 4 in East Gansu Winter Wheat Regional Test. The plant height is 78.0 cm， the 1000-grain weight is 42.0 g and the bulk density is 800.0 g/L. The average of panicle length， spikelets number， grains per spike number and panicle number are 7.6 cm， 15.2， 34.0， 345，000 panicles， respectively. The crude protein content is 162 g/kg(dry base)， lysine content is 3.6 g/kg， wet gluten content is 374 g/kg(14% moisture base)， precipitation value is 44.0 mL (14% moisture base)， total ash content is 130 g/kg， water content is 93.6 g/kg. This cultivar high-yield and stable-yield， widely suitable for water saving， neat panicle layer， good ripening， which was strong resistance to stripe rust， medium resistance to leaf rust and powdery mildew， good resistance to cold and drought， strong resistance to spring cold. It is suitable to be grown in the East of Gansu Province， Changwu， Ganxian and Binxian of Shaanxi Province， Guyuan of Ningxia and dry and fertile land and water platform of other similar ecological areas.
