| Abstract: | As one of the major food crops of the world,rice is susceptible to major pests such as stem borers,rice planthoppers,rice weevil,that cause the reduction of yield.In order to improve the insect resistance of water-saving and drought resistant rice,Huahui No.1(TT51)was used as Cry1Ab/Ac gene donor to cross with Hanhui No.3,a water-saving and drought-resistance rice restorer line.The target gene was screened by molecular marker assisted selection(MAS)technology,and BC3F4homozygous and stable lines were obtained.Through qualitative and quantitative detection of Cry1 Ab/Ac protein,combined with field agronomic traits and insect resistance observation,a new insect resistant restorer line Hanhui 3 T was selected.The results showed that compared with the control Hanhui No.3,Hanhui 3 T had similar agronomic traits,but obvious resistance to Cnaphalocrocis medinalis.The hybrid plants of Huhan 5 A/Hanhui 3 T were also highly resistant to Cnaphalocrocis medinalis,while the control hybrid plants of Huhan 5 A/Hanhui No.3 were damaged by Cnaphalocrocis medinalis.The results of this study provide a material foundation for breeding new insect resistance rice varieties with water saving and drought resistance. |
