- 摘要:
- 为促进优质玉米新品种嫩单47的推广应用，介绍了其选育过程、特征特性、产量表现和主要栽培技术。嫩单47是黑龙江省农业科学院齐齐哈尔分院玉米研究所于2017年以玉米自交系7076A1为母本，以玉米自交系K165101B为父本组配而成的杂交组合。2021－2022年参加黑龙江省齐顺联合体玉米区域试验，两年平均产量为10 668.0 kg·hm-2，比对照品种德美亚1号平均增产7.6%。2023年参加黑龙江省齐顺联合体生产试验，平均产量为10 372.6 kg·hm-2，比对照品种德美亚1号增产7.4%。2024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2024L0061。嫩单47具有抗倒伏、抗病害、耐密植、优质、高产、籽粒后期脱水快、适宜机械化收获等特性，适合在黑龙江省第四积温带地区种植。
- Abstract:
- In order to promote the promotion and application of the new high-quality maize variety Nendan 47, this article introduced its breeding process, characteristics, yield performance, and main cultivation technology. Nendan 47 was a hybrid combination created by the Maize Research Institute, Qiqihar Branch, Heilongjiang Academy of Agricultural Sciences in 2017, maize inbred line 7076A1 was used as the female parent and maize inbred line K165101B was used as the male parent. From 2021 to 2022, participated in the Qishun Joint Maize Regional Trial in Heilongjiang Province, with an average yield of 10 668.0 kg·ha-1 over two years, an average increase of 7.6% compared to the control variety Demeiya 1. In 2023, participated in the production trial of Qishun Joint Venture in Heilongjiang Province, with an average yield of 10 372.6 kg·ha-1, an increase of 7.4% compared to the control variety Demeiya 1. Approved by the Crop Variety Approval Committee of Heilongjiang Province in 2024, with approval number as Heishenyu 2024L0061. Nendan 47 has the characteristics of lodging resistance, disease resistance, dense planting tolerance, high quality, high yield, as well as fast dehydration of grains in the later stage, suitable for mechanized harvesting, and is suitable for planting in the fourth temperate zone of Heilongjiang Province.
