本文总结了阜科玉1号的选育过程、栽培特性及栽培技术要点。该品种是以自选系FS0744为母本、FS0770为父本进行杂交组配选育的玉米品种,2024年通过安徽省品种审定委员会审定(皖审玉2024T009)。该品种株型半紧凑,全生育期约100 d;区域试验中,其平均株高262.5 cm、千粒重310.0 g;对小斑病、茎腐病抗性稳定,综合抗性表现优良;品质分析显示,其籽粒容重在732~742 g/L,粗蛋白含量10.34%~10.59%;多年多点试验表明,该品种高产稳产,较对照郑单958增产7.62%~18.60%。该品种适宜在淮河以北夏播玉米产区种植,栽培技术要点包括以下环节:整地时施足基肥,施用颗粒杀虫剂防治地下害虫;在5月中旬至6月上旬夏播,种植密度63 000~67 500株/hm2;播前晒种并进行种子包衣或药剂拌种,以防治病虫害、培育壮苗;田间管理阶段应适时间苗、定苗,加强中耕除草与肥水管理,并在穗期结合追肥进行培土;花粒期补施肥水,防止早衰;成熟期适时晚收,待籽粒乳线消失、出现黑色层时机械收获,并及时晾晒至含水量14%以下安全储藏。本文为该品种在相似生态区推广应用提供参考。

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.
