抗稻瘟病水稻两系不育系海文486S的选育与应用
Breeding and Application of Two-line Sterile Line Haiwen 486S with Resistance to Rice Blast
摘要
Abstract
Haiwen 486S,derived from the cross between Xiangling 628S,a two-line male sterile line,as the female parent and Huazhan,a high-quality and blast-resistant rice variety,as the male parent,is a two-line sterile line developed by the Institute of Food Crops,Hainan Academy of Agricultural Sciences after selection for multiple generations in multiple locations.It has the advantages of low critical sterility-inducing temperature,resistance to rice blast,good grain quality and a high outcrossing rate.It was approved by Hainan Provincial Crop Variety Appraisal Committee in 2021.The new hybrid rice combination Hailiangyou 7139 derived from Haiwen 486S and the restorer line Haihui 7139 was approved by Hainan Provincial Crop Variety Appraisal Committee in 2024.This paper introduced the breeding process,characteristics,F1 hybrid performance and key technical points in the multiplication and hybrid seed production of Haiwen 486S.关键词
