Abstract："Tongyu 1701"is a new hybrid maize variety bred by Jiangsu Yanjiang Area Institute of Agricultural Sciences with the inbred line"SSG-1"as the maternal parent and"DK516"as the paternal parent.Through the national southeast common corn regional test during 2017-2018,production test in 2019,it was approved by the National Crop Variety Approval Committee in 2021,and was named Tongyu 1701(Approval Number:Guoshenyu 20210682).It has high yield potential,and the average yield of the two years was 584.60 kg/667 m2 in the national southeast common maize regional test from 2017 to 2018,which was 5.94％higher than that of the control variety"Suyu29".It has growth period of 101 days,plant height of 254 cm,ear height of 96.4 cm,lodging rate of2.5％,broken ear rate of 1.1％,ear length of 18.6 cm,14-16 rows per ear,bare cusp length of 0.9 cm,and 100-grain weight of 30.4 g.It has good resistance to environmental stress and is suitable for fully mechanized production.The paper introduced the parental origin,breeding process,yield,resistance,characteristics,main cultivation techniques,suitable planting areas and application prospects of Tongyu 1701.
