Abstract：Ganyu 759 is a new corn cultivar with high-yield， good-quality and multi-resistance， which is suitable for planting in northwest spring corn region， and the parent combination is WG4597/WG606， which was bred by Gansu Wugu Seed Industry Co.， LTD.. It was selected and composited in Hainan in 2013. In 2014， the yield was significantly higher than that of the control with prominent resistance. In 2018 — 2019， the average yield in 2 a were 15 163.8 kg/hm2 and 16 042.9 kg/hm2， 3.7% and 3.3% higher than the control cultivar Xianyu 335 in Spring Corn Regional Test in Northwest China， The yield increased at 26 sites（times） in 36 sites（times） in two years， and the proportion of increased yield was 72.2%. The grain contain of crude protein was 92.1 g/kg， crude fat was 46.1 g/kg， crude starch was 744.5 g/kg， lysine was 2.9 g/kg and bulk density was 769 g/L. It is suitable to be grown in northwest spring planting corn area.

玉米是全世界也是我国种植范围最广、用途最多、总产量最高的作物，是重要的饲料、工业原料和能源作物，发展玉米生产对保障我国粮食安全和满足市场需要发挥着至关重要的作用[1 ]。我国西北春玉米种植区主要分布在甘肃、新疆、宁夏和内蒙古，由于光照丰富、气候干燥、灌溉便利等优越条件，是全国重要的玉米高产区。近年来我国玉米高产记录由新疆创建和保持[2 - 3 ]。先玉335是本区的代表品种，但由于近年来先玉335抗病性减弱，需要更加适应环境变化和抗病、抗逆性更好、产量更高的玉米新品种。我们根据西北春玉米玉米产区的现状，以高产稳产优质多抗和耐密为育种目标，采用系谱法选择，充分挖掘和改良国内外种质资源，选育出高配合力、抗逆性强、耐密的优良自交系WG4597和WG606，并组配而成的杂交种甘玉759，具有丰产、优质、稳产、适应性广等优点，推广应用前景良好。……
