长单525是山西省农业科学院谷子研究所于2003年以外引自交系KY9903为母本,以自选自交系KY414-6为父本杂交选育而成的早熟高产玉米单交种。在各级试验中,长单525表现为高产、稳产、多抗,适宜在山西省春播玉米特早熟区、中南部复播区及有效积温在2 000℃以上的同类地区种植,每公顷留苗5.25万～6.00万株。
Changdan 525 is of early maturing and high yield mixed maize hybrid with introduced inbred KY9903 as female parent and optional inbred KY414-6 as male parent.
