Characteristics and Whole-process Mechanized Cultivation Techniques of New Maize Variety“Tongyu 1701”with Early Maturity,High Quality and Multi-resistance

通玉1701是江苏沿江地区农业科学研究所用自育自交系“SSG-1”为母本、“DK516”为父本配制杂交玉米新组合,通过2017—2018年国家东南普通玉米区域试验,2019年生产试验,2021年国家农作物品种审定委员会审定,定名为通玉1701,审定编号为国审玉20210682。该品种丰产性好,2017—2018年在国家东南普通玉米区域试验中,2年平均产量584.60 kg/667 m^(2),比对照苏玉29增产5.94%,全生育期101 d,株高254 cm,穗位高96.4 cm,倒伏率2.5%,倒折率1.1%,穗长18.6 cm,穗行数14~16行,秃尖长0.9 cm,百粒质量30.4 g,抗逆性好,适宜全程机械化生产。本文详细介绍了通玉1701的亲本来源、选育过程、产量抗性表现、特征特性、主要栽培技术、适宜种植的区域及其推广应用前景。

“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 m^(2) 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 of 2.5%,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.
