摘　　要：粮饲兼用玉米作为青贮玉米的一种类型,近年来在保障国家粮食安全及发展青贮饲料方面,作用愈发明显。宿迁是江苏省农业大市,在保障全省粮食生产、稳定畜牧业发展方面发挥了不可替代的作用。为了筛选适合当地种植的粮饲兼用玉米品种,本研究进行了粮饲兼用玉米品种鉴定比较试验。结果表明:5个品种在2021年均表现出了较高的抗性水平及产量水平,综合田间农艺性状、抗性水平、果穗性状、籽粒产量及秸秆产量来看,江玉877、迁玉180株高均为240 cm左右,抗病性均在中抗以上,千粒质量、籽粒产量、秸秆产量分别均超过320 g、9000 kg/hm2、54000 kg/hm2,更加适合宿迁地区粮饲兼用玉米品种的种植需求。The corn varieties with the uses as both grain and feed belong to a type of silage corn,which have played an increasingly important role in ensuring food security and developing silage for our country in recent years.As a major agriculture city in Jiangsu Province,Suqian is irreplaceable in ensuring grain production and stabilizing the development of animal husbandry in Jiangsu.In order to select corn varieties suitable for planting in Suqian City,a comparative experiment was conducted to evaluate five corn varieties for the uses as both grain and feed.The results showed that these varieties all showed higher disease resistance and yields in 2021.In terms of agronomic traits in the field,disease resistance,ear traits,grain yield,and straw yield,the two varieties Jiangyu 877 and Qianyu 180 both had the plant height about 240 cm,high or moderate resistance to multiple diseases,the 1000 grain weight over 320 g,the grain yield over 9000 kg/hm2,and the straw yield over 54000 kg/hm2.Thus,Jiangyu 877 and Qianyu 180 meet the standards of the corn variety used as both grain and feed for planting in Suqian area.
