“鲁原单4号”是山东省农业科学院原子能农业应用研究所于1974年用钴—60r射线处理育成的自交系“原武02”作母本,“威凤322—1”作父本杂交育成的早熟玉米单交种。我县1976年开始引种,经过二年的多点试验,该品种表现较好。在夏涝、低温、光照不足、发病重的1976年,松山大队农科队亩产787斤,在省、地、县三个联合组,26个夏直播品种试验中,“鲁原单4号”产量占第一位,比对照“烟三6号”增产25.7％。
“Luyuan single 4” is the Shandong Academy of Agricultural Sciences Institute of Atomic Energy in 1974 with cobalt -60r-ray treatment of bred inbred line “Wuwu 02” as the female parent, “Wei Feng 322-1” as male parent breeding Early maturing corn single cross. My county started introduction in 1976, after two years of multi-point test, the species performed better.
