个人中心收藏查看我的收藏0有用+10播报讨论上传视频中科院与天津农科院联合培育的大豆新品种（中作）是由中国科学院联合天津市农业科学院组织全国18个省区科研机构攻关培育的大豆新品种。该种质由中科院牵头，联合天津农科院组织全国18个省区科研机构组成攻关小组，通过对国内外46个大豆品种进行试验对比、组系合并及南繁加代繁育，经多次杂交选育而成。研究过程中采用了高新技术手段，最终成果被列为国家高新技术和最新科技成果重点推广计划项目 [1]。作为豆科巢菜属栽培种质，其染色体数目为2n=12（部分变种2n=14），具有典型的偶数羽状复叶结构和扁长形荚果特征。该品种适应冷凉湿润气候，在pH值6.5-8.0的土壤中表现出强固氮能力 [2]。培育单位中国科学院、天津农科院 [1]
培育时间20世纪90年代 [1]
所属科属豆科巢菜属 [2]
成果计划国家高新技术推广项目 [1]
适应区域温带及亚热带冷凉区 [2]
染色体数2n=12 [2]

目录
1培育历程2农业特性3推广价值4种质保存5形态特征
培育历程
播报编辑1997年公布的培育记录显示 [1]：攻关组历时多年完成46个亲本品种的杂交试验采用组系合并技术整合优良性状通过南繁加代繁育缩短育种周期最终育成品种通过国家品种审定
农业特性
播报编辑该种质在栽培中表现出显著特性 [1]：发芽适温范围4-16℃，低于多数豆科作物全生育期需水量达800 1000毫米根瘤菌固氮效率达40-60kg/公顷对赤斑病、锈病表现中等抗性
推广价值
播报编辑根据1997年国家科技推广文件 [1]：被列为全国17个重点推广农业科技成果之一在黄淮海平原试验中较当地品种增产12-18%蛋白质含量达到39.2%，油脂含量21.5%截至2016年，其衍生品种在青海等地累计推广逾5万公顷
种质保存
播报编辑国际干旱地区农业研究中心（ICARDA）种质库保存有该品种的6个基础株系 [2]，中国农业科学院作物科学研究所持续开展高产大豆新品种'中作'的培育研究 [1]。
