|
摘要
绵单1273是绵阳市农业科学研究院和四川国豪种业股份有限公司以自育系绵723和引自四川省农科院作物所自交系成205-22组配而成的玉米杂交种,2017年通过国家审定。绵单1273西南春播生育期116 d左右,在我国西南区2014—2015年区域试验中平均产量8 821.5 kg/hm~2,较平均值增产3.5%,增产点率85%;2016年生产试验,平均产量9 165.0 kg/hm~2,比对照渝单8号增产8.9%,增产点率95%。籽粒容重750 g/L,粗蛋白含量9.87%,粗脂肪含量3.89%,粗淀粉含量74.74%,赖氨酸含量0.32%。绵单1273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春播推广种植。该品种具有高产稳产性好、品质优良、抗逆性强、适应范围广等突出特点,推广应用前景广阔。
Miandan 1273 is a maize hyrid variety of Mian 723 and 205-22,which was approved by the state in 2017.Growth period of Miandan 1273 in southwest in spring seeding was about 116 d.The average yield in regional test in 2014-2015 was 8 821.5 kg/hm~2 in southwestern China,enhanced by 3.5% compared with the average value with the increasing site rate being 85%.In production test in 2016,the average yield was 9 165.0 kg/hm~2,enhanced by 8.9% compared with control Yudan 8 and with the increasing site rate being 95%.Grain volume weight was 750 g/L,crude protein content was 9.87%,crude fat content was 3.89%,crude starch content was 74.74%,lysine content was 0.32%.Miandan 1273 was suitable to be extended in spring in flatland and low mountain areas of Sichuan,Chongqing,Yunnan,Guizhou,Guangxi,Hunan,Hubei,Shaanxi.Miandan 1273 has the characteristics of high yield,stable yield,good quality,strong stress resistance,wide application range and so on,having broad application prospect.
