Jiuyang 528(YDF 528) is a new corn hybrid, bred with selfselected line FH5263 as female parent and self-selected line FH088 as male parent. In 2014 — 2015, the average yield in 2 a was 11 244.0 kg/hm2, 6.7% higher than the control shendan16 in Gansu Corn Regional Test. In 2016, the average yield of Jiuyang 528 was 11 299.5 kg/hm2, which was 8.0% higher than that of Xianyu 335 in Gansu Corn Regional Test. It has strong lodging resistance, to moderate resistance to stalk rot and ear rot, antineoplastic smut. The plants are compact. The average growth period is 138 days, belong to a medium and late ripening cultivar, plant height is 279.7 cm, 100-grain weight is 36.2 g, seed yield is 87.3%, and bulk weight is 775.0 g/L. The content of crude protein (dry base) is 91.2 g/kg, crude fat (dry base)is 42.8 g/kg, crude starch (dry base) is 719.4 g/kg, and lysine(dry base) is 3.5 g/kg. It is suitable to be grown in Huining, Qinan, Qingshui, Lingtai,Zhenyuan, Huanxian of Gansu Province and other similar ecological areas.
