| Abstract: | Using "Puruan Ging S" as the parent,we have bred new two-line male sterile rice cultivars "2179S" containing high exerted stigma phenotype as well as Pi9,Pita,Pib,and Pigm rice blast resistance genes and soft rice gene(Wxmq) by molecular marker-assisted selection.The "2179S" showed strong stalks,short stems,large panicle,and itsaverage plant height was 63.8 cm.The stigma exertion rate was about 60%.The results providing sterile line parents for developing new combination of high quality two-line hybrid rice with resistance to rice blast. |
