摘要
Abstract
Liangeng 317 is a high-quality and blast-resistant geng rice variety developed by Lianyungang Academy of Agricultural Sciences through molecular marker-assisted selection and aggregation of Pi-ta and Pi-2 genes,as well as high-quality taste evaluation.This variety is early maturing,and 1.5 days earlier than the control Xudao No.3.It has strong disease resistance,with a comprehensive index of 3.7 and 3.4 for rice blast disease over two years,and moderate resistance to rice blast disease.The plant is semi compact,with a height of 99.5 cm and strong lodging resistance.It was approved by National Variety Approval Committee in 2021(Approval number:Guoshendao 20210388).This article summarizes the breeding process,main characteristics,and key high-yield and high-quality cultivation techniques of Liangeng 317 in the Huang-Huai-Hai region,in order to provide reference for the promotion and application of this variety.关键词
