The breeding process, cultivation characteristics, and key cultivation techniques of the maize variety Fukeyu No.1 were summarized. This variety was developed by crossing the inbred line FS0744 (female parent) with FS0770 (male parent) and was approved by the Anhui Provincial Variety Approval Committee in 2024 (Wanshenyu 2024T009). The plant type was semi-compact, with a total growth period of approximately 100 days. In regional trials, the average plant height was 262.5 cm, and the 1 000-grain weight was 310.0 g. Stable resistance to small spot disease and stalk rot disease, with excellent comprehensive resistance performance. Quality analysis revealed a test weight of 732-742 g/L and a crude protein content of 10.34%-10.59%. Multi-year, multi-location trials indicated that the variety was high yielding and stable, with yield increase of 7.62%-18.6% compared to the control variety Zhengdan 958. This variety is suitable for planting in summer-sown maize production areas north of the Huai River. Key cultivation techniques include the following steps: apply sufficient base fertilizer during land preparation and use granular insecticides to control soil pests; conduct summer sowing from mid-May to early June at a planting density of 63 000-67 500 plants/hm2; sun dry seeds before sowing and apply seed coating or chemical dressing to control pests and diseases and promote robust seedlings; during field management, thin and finalize seedlings in a timely manner, strengthen intertillage and weeding, and manage fertilizer and water appropriately. At the tasseling stage, combine topdressing with soil hilling; supplement water and fertilizer during the grain-filling stage to prevent premature senescence. Delay harvesting appropriately at maturity; mechanically harvest when the kernel milk line disappears and a black layer forms, and dry the grains promptly to a moisture content below 14% for safe storage. This study provides a reference for the promotion and application of this variety in similar ecological regions.
