玉米新品种潞玉1681选育报告
|
摘要
潞玉1681是由山西省农业科学院谷子研究所和山西潞玉种业玉米科学研究院以自选系LYA92为母本、自选系LYB72为父本组配而成的优良玉米单交种,2018年通过国家农作物品种审定委员会审定,审定编号为国审玉20186143。该品种产量稳定、抗倒性好,2016—2017年西南绿色通道区试平均产量为9 162.8 kg/hm~2,比对照渝单8号增产11.05%,增产点率为85.2%,倒伏倒折率为2.2%;2017年西南绿色通道生产试验平均产量为8 907 kg/hm~2,比当地对照增产6.77%,增产点率为77.5%,倒伏倒折率为1.8%。潞玉1681适宜在四川、重庆、云南、贵州、广西、湖南、湖北、陕西汉中地区的平坝丘陵和低山区等西南春玉米区种植。
Luyu 1681 was a single cross of maize, which was developed by the Institute of Millet, Shanxi Academy of Agricultural Sciences and the Shanxi Luyu Seed Industry Corn Science Institute, using self-selected line LYA92 as female parent and self-selected line LYB72 as male parent. It was approved by the National Crop Variety Committee in 2018, and its number was State-approved by20186143. The yield of this variety was stable and lodging resistance was good. The average yield of green passage regional test in southwest China from 2016 to 2017 was 9 162.8 kg/hm~2, which was 11.05% higher than that of control Yudan 8, the ratio of production increase point was 85.2% and the lodging rate was 2.2%. In 2017, the average yield of green passage production test in southwest China was 8 907 kg/hm~2, which was 6.77% higher than that of local control, the ratio of production increase point was 77.5% and the lodging rate was 1.8%. It is suitable for planting in southwestern spring maize areas such as Pingba hills and low mountain areas in Sichuan, Chongqing, Yunnan, Guizhou, Guangxi, Hunan, Hubei and Hanzhong in Shaanxi.
