本文总结了滇红727的选育过程、特征特性及栽培技术要点。该品种是以南矮29为母本,阿哲龙马河坝红米为父本,使用系谱选择方法,历经7个世代选育而成的常规优质红米品种,2022年通过云南省农作物品种审定委员会审定(滇审稻2022031号)。其生育期适中、株型好、抗倒伏、产量高,对稻瘟病、白叶枯病和纹枯病的抗性较好;2年区域试验和1年生产试验平均产量在8 732.7~9 287.2 kg/hm2;米粒红色,整精米率高,直链淀粉含量低,胶稠度高,品质符合NY/T 593—2021《食用稻品种品质》优质三等标准。该品种适宜在云南省海拔1 300 m以下的地区推广种植,采用育秧移栽时,秧龄35~40 d,密度22.5万~27.0万丛/hm2;直播需整平田块,播后灌水抑草;施肥以基肥为主、追肥早施,水分管理遵循“浅水促苗、中期晒田、后期湿润”;病虫害防治坚持预防为主、综合防治的原则,具体包括清洁田园,灯光、诱虫板诱杀,种植显花植物,喷施吡蚜酮、氟啶虫胺腈等药剂防治稻飞虱、穗颈瘟等病虫害。本文为该品种的推广种植及红米产业可持续发展提供参考。

The breeding process, characteristics, and key cultivation techniques of Dianhong 727 were summarized. This variety was a conventional high quality red rice cultivar developed through pedigree selection over seven generations, using Nan’ai 29 as the female parent and the Azhelongmaheba red rice as the male parent. It was approved by the Yunnan Provincial Crop Variety Approval Committee in 2022 (Dianshendao No.2022031). The variety exhibits moderate growth duration, excellent plant architecture, lodging resistance, and high yield. It demonstrates good resistance to rice blast, bacterial leaf blight, and sheath blight. In two-year regional trials and one-year production trials, the average yield ranged from 8 732.7 to 9 287.2 kg/hm2. The grains are red, with a high head rice rate, low amylose content, and high gel consistency, meeting the Grade Ⅲ quality standard of NY/T 593-2021 “Edible Rice Varieties”. This variety is suitable for promotion and planting in areas below 1 300 meters above sea level in Yunnan Province. When using seedling cultivation and transplantation, the seedling age is 35-40 days and the density is 225 000-270 000 clusters/hm2; direct-seeding requires leveling the field and watering to suppress weeds after broadcasting; fertilization is mainly based on base fertilizer, with early application of topdressing. Water management follows the principles of “promoting seedlings in shallow water, sun drying in the middle stage, and moistening in the later stage”. The prevention and control of disease and pests adhere to the principle of prevention first and comprehensive prevention and control, including cleaning the countryside, using lights and insect traps to lure and kill, planting flowering plants, and spraying pesticides such as pymetrozine and fipronil to control pests and diseases such as rice planthoppers and neck blight. This study provides a reference for the promotion and cultivation of this variety and the sustainable development of the red rice industry.
