Abstract: 【Objective】Researches were Couducted to screen new wheat varieties with good resistance to wheatfusarium head blight and excellent agronomic characters and quality. 【Method】 Five new lines and two control varieties tested in the regional test of wheat fusarium head blight resistance group in Henan Province were selected to carry out the identification of fusarium head blight resistance in the field by single-flower drip inoculation method for two consecutive years from 2019 to 2020 and 2020 to 2021. At the same time, their genotypes were detected by using functional markers or closely linked molecular markers with Fhb1, Fhb2, Fhb4, Fhb5, and Fhb7, and their winter and spring characteristics, yield components, main agronomic traits such as plant height and cold resistance, as well as the main quality traits such as protein content, hardness, wet gluten content and sedimentation value were measured. 【Result】 The average diseased spikelet rate of the seven tested varieties was 42.2%, the average severity was 3.0, the average 2 a yield of the tested varieties was 7 105.4 kg·hm-2, and the average tillering ear rate was 42.4%; Zhengmai 113 is weak spring, and other new wheat varieties are semi-winter; The average whole growth period of the tested varieties is 217 days, the range of resistance to winter cold is 2-3 grades, the range of resistance to spring cold is 2-4 grades, the average plant height is 76.7 cm, and the grain falling property of Bainong 207 and Jimai 1 is 3 grades, indicating they are varieties with low seed-holding capicity. The average protein content of the tested varieties was 14.8%, the average total starch content was 61.2%, the average amylose content was 19.4%, the average amylose/amylopectin ratio（amylose/amylopectin ratio） was 0.47, the average gelatinization temperature was 88.7 ℃, the average hardness index was 58.1, the average sedimentation value was 68.4, and the average wet gluten content and gluten index were 31.5% and 54.8 respectively. 【Conclusion】Molecular marker detection showed that Yunong 903 and Yunong 904 carried the fusarium head blight resistance gene Fhb1, while Jimai 1 and Zhengmai 9134 carried Fhb5. The average 2 a yield of three new semi-winter varieties, including Zhengmai 9134, Yunong 904 and Yunong 903, is better than that of the control variety Bainong 207, and the cold resistance and lodging resistance are also better than that of the control variety.Yunong 903, Yunong 904 and Zhengmai 9134 have excellent comprehensive characters and can be used as germplasm and new varieties for genetic improvement of wheat fusarium head blight resistance.
