1、适宜免耕覆秸精量播种栽培方式的夏大豆品种（系）筛选闫向前何鑫张琪孙化军寇传喜河南省商丘市农林科学院摘要：为筛选出适宜麦茬免耕覆秸精量播种栽培方式的夏大豆品种（系），运用灰色综合评判法，对来自黄淮海地区的12个夏大豆品种（系）的12个主要农艺性状进行综合分析，对各参试品系的灰色综合评判等级排序。结果表明：商豆1201、冀豆12、荷豆14的综合性状表现突出、产量高，可作为推广麦茬免耕覆秸精量播种技术的主要种植品种；郑7051、周豆22号、阜豆16及山宁19的农艺性状表现也较好，产量高于对照，可适当推广种植;皖豆21144、徐9302-A及皖

2、宿01-15灰色综合评判值低于对照，中黄39的产量低于对照，但是相差很小。本研究表明所有参试品系均适宜免耕覆秸精量播种栽培方式，免耕覆秸精量播种技术在黄淮海地区具有广阔的应用前景。关键词：麦茬免耕覆秸精量播种;灰色综合评判;夏大豆;农艺性状;作者简介：闫向前（1979-）,男，学士，助理研究员，主要从事大豆育种与栽培技术研究。E-mail:yanxiangqianl23@126.com。收稿日期:2017-05-23基金：国家重点研发计划（2017YFD0101400）Varieties(Lines)ScreeningofSummerS
