摘　　要：玉米品种黑科玉17由黑龙江省农业科学院黑河分院于2013年选育而成,2021年通过国家农作物玉米专业品种审定委员会审定,审定编号为国审玉20210157。2022年分别在北安、爱辉、嫩江、鹤山、尖山、克山做该玉米品种的适应性鉴定试验。结果表明:玉米品种黑科玉17在6个不同地点植株高度变幅为259~269 cm,穗位高变幅为77~86 cm,空秆率变幅为1.6%~5.4%,穗长变幅为19.3~22.2 cm,穗粗变幅为4.9~5.6 cm,秃尖长变幅为0.8~3.2 cm,穗行数变幅为14.0~15.4行,行粒数变幅为37.00~43.00粒,百粒质量变幅为31.6~35.7 g,出籽率变幅为75.6%~79.8%,产量变幅为9082.5~12608.6 kg/hm^(2)。该品种不同农艺性状及产量在6个不同地点综合表现均以克山县表现最好,植株茎秆强度、抗病性均较好,在各点均没有发生倒伏。该品种适合在黑龙江省第三积温带下限和第四积温带上限种植。The new maize variety Heikeyu 17 was selected and bred by Heihe Branch of Heilongjiang Academy of Agricultural Sciences in 2013.It passed the appraisal of the National Crop Appraisal Committee specialized in Maize Varieties in 2021,with the accreditation number“Guoshenyu 20210157”.In 2022,the adaptability of Heikeyu 17 was assessed in field trials conducted on six sites:Bei'an,Aihui,Nenjiang,Heshan,Jianshan,and Keshan.The results showed that its agronomic traits varied with site,with variation ranges of 259-269 cm for plant height,77-86 cm for the height of ear position,1.6%-5.4% for the percentage of hollow stalks,19.3-22.2 cm for panicle length,4.9-5.6 cm for panicle diameter,0.8-3.2 cm for the length of ear barren tip,14.0-15.4 for the number of panicle row,37.00-43.00 for kernel number per row,31.6-35.7 g for 100-kernel weight,75.6%-79.8% for kernel yield,and 9082.5-12608.6 kg/hm^(2) for yield.This variety showed the best performance in various agronomic traits and yield in Keshan County among the six sites;on the other hand,it showed strong stem strength and disease resistance on all the sites,without lodging occurring on each site.In conclusion,this variety is suitable for planting in the lower limit of the third accumulated temperature belt and the upper limit of the fourth accumulated temperature belt in Heilongjiang Province.
