Abstract: Wheat yellow mosaic virus （WYMV）, one of the most devastating diseases of cereals, also called wheat spindle streak mosaic virus （WSSMV）, has different effects on different cultivars of wheat. Breeding and growing resistant cultivars is one of the most effective method to defense WYMV. Selection of suitable parents for the formation of mapping population for QTLs mapping involved in WYMV is a basic work to breed new WYMV resistant cultivars. In this study, 527 different cultivars / lines of wheat from different districts at home and abroad were introduced and identified in disease plots with three different experimental plots and three replications each plot. Then polymorphic simple sequence repeats （SSRs） markers were screened out between resistant and sensitive parents which had a larger planting area than other wheat cultivars. Results showed that only ten of the 527 candidate materials had a relatively more stable WYMV disease resistance. Three WYMV resistant wheat cultivars out of ten resistant materials including Fengkang 1Shijiazhuang 72and Zhengmai 9023and two sensitive wheat cultivars with a wider planting area, Yangmai 158 and Yannong 22, were selected for further comparison. Higher polymorphic rates were obtained with the parental group of Fengkang 1 and Yangmai 158 （64.0%） and the parental group of Shijiazhuang 72 and Yangmai 158（63.3%） than other groups. Therefore, using WYMV resistant cultivars Fengkang 1 and Shijiazhuang 72, along with WYMV sensitive parent Yangmai 158 to form mapping populations would be more opportune for fine mapping of quantitative trait locus （QTLs） involved in WYMV resistance and map-based gene cloning. ［Ch, 2 fig. 3 tab. 17 ref.］
