Guangxi common wild rice variety brown planthopper highly resistant introgression line HS204 was taken as antigen donor material,hybridization,backcrossing,and molecular marker-assisted selection methods were adopted,to select maintainer line and sterile line materials,so as to provide excellent material foundation for resistance breeding of hybrid rice. Through the marker-assisted selection,it obtained 4 pieces of homozygous resistance gene maintainer line intermediate materials( 100B,101B,102B and 103B),and 2 pieces of resistant sterile line materials( 100A and 103A). All 10 combinations that have testcross with highly resistant sterile 100A showed higher level of brown planthopper resistance: 100A/R2586,100A/KR838,and 100A/KR527 had high resistance level,the others had low to intermediate resistance;100A/KR527,100A/R2586,100A/Minghui 63,100A/Fuhui 838 and 100A/Gui 99 combinations had yield per plant significantly higher than the control group( Teyou 7118),increasing by 14. 45%-49. 26%. The obtained resistant lines are expected to provide a better gene source for the breeding of resistant sterile lines of hybrid rice and the obtained resistant sterile lines can be directly used in the selection of three-line hybrid rice.
