摘　　要：【目的】为新品种进一步推广应用提供科学依据。【方法】以广西主栽玉米品种作对照,经两年区域试验和生产试验鉴定,研究玉米新品种"农职802"亲本来源与选育过程及其农艺性状。【结果】"农职802"以自选系"M88-/hm2,比对照增产5. 0%,增产点/hm2,比对照桂单162增产4. 9%,增产点次占87. 5%。抗病性接种鉴定:中抗小斑病、感大斑病、纹枯病、穗腐病、南方锈病及茎腐病。【结论】"农职802"具有高产、稳产、适应性广、耐旱耐瘠等特点,适宜在广西各地区及相似生态区种植。【Objective】To provide technical support for further popularization and application of new variety.【Method】"Nongzhi 802"was produced by cross breeding of"m88-1"as the mother line and"Y102"as the father line.The main maize varieties in Guangxi were used as control,and were identified by two years of regional test and production test.The breeding process,characteristics and high yield cultivation technology of"Nongzhi 802"were described.【Result】During the spring and autumn 2016 regional test average yields 7965.0㎏/hm^2,a 5.0%increase in production,production time 84.5%.During the spring and autumn in 2017,production test average yields 7692.0㎏/hm^2,yield increased by 4.9%,compared with single 162 Guangxi yield point time accounted for 87.5%.Identification of disease resistance inoculation:medium resistance to small spot,sensory-large spot,grain blight,ear rot,southern rust and stem rot.【Conclusion】"Nongzhi 802"has the characteristics of high yield,stable yield,wide adaptability,drought and poor tolerance,etc.,which was approved by Guangxi variety examination in 2018 and is suitable for planting in various regions and similar ecological zones of Guangxi.
