Abstract: The new wheat variety Chang 6990 was used as the material, using 59 pairs of molecular markers, including adaptability, grain size, quality and stress resistance, developed by Professor He Zhonghu research group of Crop Sciences, Chinese Academy of Agricultural Sciences, high-throughput KASP typing technique was used to detect the whole genome of Chang 6990. The results showed that among the 11 genes related to adaptability, Chang 6990 contained 7 excellent allelic variations, and the excellent variation rate was 63.6%. Among the 10 loci related to grains, Chang 6990 contained excellent alleles of TaSus1-7B, TaSus1-7A, TAGS5-A1 and GW2-6B, and the aggregation of these excellent loci could be an important reason for its high yield. Among the 12 quality related genes, Chang 6990 contained 5 excellent allelic variations, and the excellent allelic variation rate was 41.7%. In terms of disease resistance, Chang 6990 aggregated two major leaf rust resistance genes（Lr14a, Lr46） and an important scab resistance gene（Fhb1）, which was the reason for its outstanding disease resistance.Among the 6 gene loci related to stress resistance, 2 excellent mutation loci were detected, which were Phs1 for resistance to spike germination and Dreb-B1 for drought resistance, and the drought resistance loci was a slight effect loci. It was speculated that the outstanding drought resistance characteristics of Chang 6990 might be regulated by other loci, which pointed out the direction for the next step of stress resistance gene excavation.
