AbstractThe breeding process，cultivation characteristics，and key cultivation techniques of the maize variety Fukeyu No.1 were summarized.This variety was developed bycrossng the inbred line FSO744（female parent） with FS0770 （male parent）and was approved by the Anhui Provincial Variety Approval Commitee in 2O24 （Wanshenyu 2024T009）.The plant type wassemi-compact， with a total growth period of approximately10O days.Inregional trials， the average plant height was262.5cm，andthe1O0O-grain weight was 310.0 g.Stable resistance to smallspot disease and stalk rotdisease，with excellent comprehensive resistance performance.Quality analysis revealed atest weight of 732-742g/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 maizeproductionareas north of the Huai River.Keycultivation techniques include the following steps：apply sufficient base fertizer during land preparationandusegranular insecticides to control soil pests;conduct summer sowing from mid-Mayto early June at a plantingdensityof 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，thinand finalize seedlings in a timely manner， strengthen intertilageand weeding，andmanage fertilizerand waterappropriately.Atthetasselingstage，combine topdressing with soil hiling;supplement waterand fertilizer during the grain-filling stage toprevent 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.
