稳产丰产优质玉米新品种"先丰9号"是山西农业大学小麦研究所2014年以X460为母本,X433为父本配制杂交组合,采用系谱法选育而成.2018-2019年分别参加山西省玉米春播中晚熟区区域试验,两年所有试点全部增产且平均产量为13 207.3 kg/hm2,较对照"先玉335"增产7.7％.2020年参加山西省玉米春播中晚熟区生产试验,较对照增产的试验点比例为100％,平均产量12 685.5 kg/hm2,较对照增产5.3％.籽粒容重774 g/L,粗蛋白含量9.7％,粗脂肪含量3.65％,粗淀粉含量75.74％.2021年通过山西省主要农作物品种审定委员会审定,审定编号为:晋审玉20210019,适宜在山西春播中晚熟玉米区种植.
Abstract
The new maize variety"Xianfeng 9"with stable and high yield as well high quality was bred by genealogi-cal method in 2014 by Wheat Research Institute of Shanxi Agricultural University(Shanxi Academy of Agricultural Sciences).The maternal parent and male parent were X460 and X433,respectively.The regional test results in middle and late cropping area of spring maize in Shanxi Province showed that,the maize yield in all sites increased both in 2018 and 2019 with an average yield of 13 207.3 kg/ha,which was 7.7％higher than the control"Xianyu 335".In 2020,the production test results in middle and late cropping area of spring maize in Shanxi Province showed that,and the increased proportion of test sites compared with the control was 100％,with an average yield of 12 685.5 kg/ha and an increase of 5.3％.In the same year,the grain was determined as,774 g/L of bulk weight,9.7％of crude protein,3.65％of crude fat,and 75.74％of crude starch.In 2021,it was approved by Shanxi Provin-cial Main Crop Variety Approval Committee,and the approval number was Jinshenyu 20210019,which was suitable for planting in middle and late cropping area of spring maize in Shanxi Province.
