籼稻红米品种滇红727的选育与栽培技术
Breeding and cultivation techniques of indica red rice variety Dianhong 727
摘要
Abstract
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.关键词
