机械粒收玉米新品种德科501的选育及夏播轻简化栽培技术

Breeding of Mechanical Grain Harvest Summer Maize Variety Deke 501 and its Simplified Cultivation Technology

为推动玉米规模化和机械化生产,德州市农业科学研究院以玉米自选系Q2038K为母本、Q8012A为父本进行杂交,成功选育出适宜机械粒收的玉米新品种德科501,该品种具有耐密、抗倒、优质、高产、脱水快及适宜机械粒收等特性,于2019年通过山东省农作物品种审定委员会审定(审定编号:鲁审玉20190008);提出德科501的轻简化栽培技术及种子生产技术要点。

To promote large-scale and mechanized production of maize,a new maize variety Deke 501 was bred from the combination of Q2038K(female parent)×Q8012A(male parent)by Dezhou Academy of Agricultural Sciences.This variety had many advantages such as density tolerance,lodging resistance,high quality,high yield,fast dehydration,and mechanical grain harvest.Deke 501 was approved by Shandong Crop Variety Approval Committee in 2019(Lushenyu 20190008).In this paper the authors proposed simplified cultivation technology and seed production technology of Deke 501.
