Abstract

In this study,we developed a new rice strain,"Shangshida No.18",by molecular marker-assisted gene pyramiding,using aromatic and soft rice "Qingxiangruanjing" as the parent donor of soft rice gene and using aromatic and non-soft rice "Guangmingjing No.2" as a backcross parent.The growth duration of developed "Shangshida No.18" rice was about 148 days,5 days shorter than that of "Qingxiangruanjing" rice,and there were no significant difference in agronomic and yield traits of "Shangshida No.18" rice and "Guangmingjing No.2"rice.Amylose content of "Shangshida No.18" rice was 8.2%,which belongs to range of soft rice.The successful development of the new rice line "Shangshida No.18" has laid a solid foundation for the further production of aromatic and soft rice with shorter growth duration in Shanghai.
