以春小麦纯系Ｋ２０２的幼穗为外植体，用１０００Ｒａｄ的６０Ｃｏγ射线照射后，进行组织培养。将根腐病菌粗毒素加在诱导、继代和分化培养基中进行细胞筛选。对获得的无性系后代进行系谱法选育。选育过程中，在温室及田间用根腐病菌孢子悬浮液接菌筛选鉴定。１９９０年决选出优良品系龙辐８３１９９。经抗性、产量和品质鉴定后，表现优异，于１９９８年２月经黑龙江省审定命名推广。
The young spikelets of spring wheat line K202 were used as explants and irradiated with 60Coγ ray of 1000Rad after the tissue culture. The root rot pathogen crude toxin was added to induced, subcultured and differentiated medium for cell selection. Pedigree selection of the clones obtained. Breeding process, in the greenhouse and field with root rot bacteria spore suspension bacterial strain selection identification. In 1990 the election of a good strain of Long Spray 83199. After resistance, yield and quality identification, outstanding performance, in February 1998 by the Heilongjiang Province validation named promotion.
