沈单7号是沈阳市农业科学研究所1982年以自选系5003做母本,丹东市农科所E28做父本杂交而成。1983～1984年参加沈阳市农科所内比较试验,亩产689.2公斤,比对照增产22.5％。1985～1986年参加辽宁省区域试验,比对照种(中单2号、丹玉13)
Shen No. 7 is Shenyang Institute of Agricultural Sciences in 1982 to choose 5003 as the female parent, Danton Institute of Agricultural E28 father made hybrid. From 1983 to 1984, he took part in a comparative experiment in Shenyang Agricultural Science Institute, with a yield of 689.2 kilograms per mu, an increase of 22.5% over the control. From 1985 to 1986 to participate in regional experiments in Liaoning Province, compared with the control (Zhongdan 2, Dan Yu 13)
