摘　　要：为筛选适合淮北区夏玉米机械粒收新品种,促进机械粒收技术在该区域的推广应用,加快优良品种推广,于2020年选取淮北不同生态条件的5个试验点,对9个夏玉米区审定的品种开展了玉米机械粒收品种筛选试验。对不同品种的生育期、籽粒含水率、籽粒破碎率、产量、倒伏倒折率和茎腐病发病率等进行测定和分析,以参试品种平均产量和收获期平均籽粒破碎率为指标,采用双向平均作图法,综合各品种丰产性、稳产性和区域适应性,初步筛选出丰产性和稳产性好、在淮北区适应性广、耐密植、抗倒性好且籽粒脱水快的品种苏科玉206,可推荐为淮北区适宜机械粒收备选品种。The purpose of this study was to screen out grain mechanical harvesting,promoting the application of maize mechanized grain harvesting technology,which was scaling up new suitable varieties in Huaibei area.With nine summer maize varieties in different ecological areas of the Huaibei,the screening experiments of mechanical kernel harvest were carried out in five different typical ecotype locations in 2020.The growth period,grain moisture content,grain breaking rate,yield,lodging and breaking rate and stem rot incidence of different varieties were determined and analyzed.With the average yield of varieties and the average grain breaking rate during harvest period as the indexes,the bidirectional average mapping method was used to comprehensively evaluate the high yield,stable yield and regional adaptability of each variety,the variety Sukeyu 206 with high and stable yield,widely adaptation,dense planting resistance,lodging and discount resistance,fast-dehydrated was selected,which was suitable for mechanical kernel harvest in Huaibei area.
