摘要:
为促进玉米新品种合玉123的推广应用，本文详细介绍了其选育过程、产量表现、特征特性及相关栽培技术。合玉123是黑龙江省农业科学院佳木斯分院以自交系合选04为母本，以自交系合选21为父本杂交选育而成的玉米新品种。2018－2019年参加黑龙江省联合体区域试验平均产量为11 119.8 kg·hm-2，较对照品种德美亚3号增产8.1%；2020年参加黑龙江省联合体生产试验平均产量为11 910.9 kg·hm-2，较对照品种德美亚3号增产7.1%。2021年通过黑龙江省农作物品种审定委员会审定，审定编号：黑审玉2021L0020。合玉123增产潜力大，稳产性好，抗病抗逆性强，适宜在≥10 ℃活动积温2 400 ℃左右区域种植。
Abstract:
In order to promote the popularization and application of a new maize variety Heyu 123，the breeding process， yield performance， characteristics and related cultivation techniques were introduced in detail in this paper.Heyu 123 is a new corn variety，it was bred by Jiamusi Branch of Heilongjiang Academy of Agricultural Sciences，with self bred dent type line Hexuan 04 as female parent and self bred Medium flint type line Hexuan 21 as male parent. From 2018 to 2019， the average yield of participating in the regional trial of Heilongjiang Province consortium was 11 119.8 kg·ha-1，increasing by 8.1% compared to the control variety Demeiya 3. In 2020，the average yield of the consortium production experiment in Heilongjiang Province was 11 910.9 kg · ha-1， increasing by 7.1% compared to the control variety Demeiya 3. In 2021，it was be approved by the Heilongjang Crop Variety Approval Committee，appronal number was Heishenyu 2021L0020.It has the characteristics of high yield potential，high and stable yield，strong resistance to disease and stress. This variety is suitable for planting in the accumulated temperature≥10 ℃ and the active accumlated temperature is above 2 400 ℃.
