Abstract: In order to promote the new millet variety Chenggu 17（15-M328） resistant to imidazolium nicotinic acid herbicide, this article introduces the breeding process, characteristic characteristics, yield performance, and cultivation points of this variety. Chenggu 17 is a new variety developed by the Crop Research Institute of Chengde Academy of Agriculture and Forestry, using Chenggu 9 as the female parent and K359×M4-1 as the male parent for cross breeding. It was successfully bred through continuous self breeding using the pedigree method. The average yield of variety identification experiments from 2016 to 2017 was 4 991.6-6 634.8 kg · ha^-1, which increased by 10.82%-23.66% compared to the control variety Chenggu 13. The average yield of the regional adaptability joint identification test for grain varieties in China from 2018 to 2019 was 4 925.3 kg · ha^-1, which increased by 14.9% compared to the control variety Chenggu 13. In 2020, it was registered as a national non major crop variety with registration number GPD millet（2020） 130113. Chenggu 17 has a high, stable yield, and good comprehensive characteristics. The growth period of this variety is about 122 days, with a plant height of 135.70 cm, an ear length of 25.30 cm, an ear diameter of 3.52 cm, a single ear weight of 26.00 g, a thousand grain weight of 2.58 g, and a grain yield rate of 82.9%. It is suitable for planting in the middle and late maturing areas of the spring millet region in Hebei Province.
