Breeding and Characteristic Analysis of a New Three-Line Hybrid Rice Combination'Hexiangyou 1798'
摘要
Abstract
This paper introduces the breeding process and varietal characteristics of the new three-line hybrid rice combination"Hexiangyou 1798".Based on high-quality germplasm,the variety was developed through systematic breeding using the three-line method over more than ten years,and was approved in Guangxi in 2023.Regional trials demonstrated that"Hexiangyou 1798"outyielded the check varieties at most test sites in central,northern,and southern Guangxi,with particularly prominent yield potential in high-altitude cold regions.Agronomically,it exhibits large panicles with high grain number,a slightly earlier growth duration,and relatively high seed-setting rate.The rice grain quality is excellent,with several key indices meeting the first-grade criteria of the Chinese Ministry standard.However,the variety shows weak resistance to bacterial leaf blight,so it is necessary to strengthen disease prevention and control in production.It is suitable for cultivation as early or late season rice as well as a single-season medium rice across multiple ecological regions of Guangxi,and corresponding cultivation and seed-production techniques are also provided.关键词
