摘要:

多抗广适型玉米新品种东裕606是由沈阳东裕种业有限公司2014年利用国外血缘×国内血缘的远缘杂优模式，采用传统常规育种技术，通过系谱选育法筛选，择优选育产量高、抗病性强、抗倒性突出、配合力优的亲本自交系P6270和K8872杂交组配而成。本研究阐述了东裕606的品种及亲本来源、品种特征特性和产量表现，并总结了高产栽培以及制种技术，以期为该品种的推广提供技术支撑。

Abstract:

Dongyu 606, a new multi-resistant and widely adaptable maize variety, was developed by Shenyang Dongyu Seed Industry Co., Ltd. in 2014. Adopting the distant heterosis model of foreign germplasm × domestic germplasm, the variety was bred by integrating traditional conventional breeding techniques with pedigree selection to screen and select parental inbred lines P6270 and K8872, which exhibit high yield potential, strong disease resistance, prominent lodging resistance, and excellent combining ability. This study elaborates on the origin of Dongyu 606 and its parents, as well as the variety's characteristics and yield performance. Additionally, it summarizes high-yield cultivation and seed production techniques, aiming to provide technical support for the promotion of this variety.
