The breeding process, variety characteristics, seed production techniques, and cultivation techniques of Hangyan 9013 were summarized. This variety is a maize variety developed by crossbreeding M141 as the female parent and HY188 as the male parent. It was approved by the National Crop Variety Approval Committee in 2021 (Guoshenyu 20210430). This variety has a plant height of 288 cm, a grain density of 746 g/L, a hundred grain weight of 35.3 g, and a yield of 673.1-713.8 kg/667 m2. It has the characteristics of high yield and lodging resistance. The key points of its seed production technology include selecting medium to high fertility plots with flat and well isolated conditions; the seeds are coated with fungicides such as fludioxonil, metalaxyl-M, and clothianidin; apply 2 500-6 000 kg/667 m2 of organic fertilizer for farmers or commercial, 20-25 kg/667 m2 of phosphorus fertilizer, 10 kg/667 m2 of potassium sulfate, and 2 kg/667 m2 of zinc fertilizer as base fertilizer; film covered hole sowing in mid April, with a parent to parent ratio of 1∶5-1∶6; seedlings are established at the 3-5 leaf stage, and the female parent is plucked and the male parent is removed. After manual pollination is completed, the male parent plants are removed harvest after maturity and promptly dry to a moisture content of ≤ 13%. The key points of high-yield cultivation techniques include selecting coated seeds (with a purity of ≥ 99% and a germination rate of ≥ 93%) before sowing, creating moisture and sow directly after wheat harvest, with a density of 4 500-5 200 plants/667 m2; chemical weeding before or after the four leaf stage of seedlings; 40-50 kg/667 m2 of compound fertilizer, 500-1 500 kg/667 m2 of organic fertilizer, 1-2 kg/667 m2 of zinc fertilizer, 15-25 kg/667 m2 of urea twice during the horn mouth period, and spraying potassium dihydrogen phosphate and urea during the flowering and grain stage to prevent premature aging; after mid August, pour grouting water and harvest mechanically after the milk line disappears. This article provides a reference for further promotion and planting of this variety.
