| 以香型软米水稻"青香软粳"作为软米基因供体亲本，以香型非软米水稻"光明粳2号"作为转育亲本，结合软米基因分子标记辅助筛选，成功培育出香型软米水稻"上师大18号"."上师大18号"水稻全生育期约148 d，早于"青香软粳"水稻约5 d."上师大18号"水稻主要农艺性状和产量性状都与"光明粳2号"接近."上师大18号"稻米直链淀粉质量分数为8.2%，符合软米特征."上师大18号"水稻的成功选育有助于上海地区推广生育期相对较短的香型软米水稻. |

| 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. |
