Characteristics of Resistance to Brown Planthopper and Breeding Utilization of R318 |
| |
| Abstract: | Objective]Characteristics of resistance to brown planthopper and breeding utilization of R318 were studied.Method]With TN1, RHT and B5 as control, resistances to brown planthopper in field of the R318 and its derived strains were identified.Molecular detection of R318 and its derived strains was done by primer MS5 of resistance gene Bph15.Result] R318 was manifested as resistance to brown plan-thopper by field identification, its derived strains were manifested as medium resistance-susceptibility to brown planthopper.R318 and its de-rived strains have indistinguishable fingerprinting patterns with B5 by molecular identification. Conclusion] It is considered R318 and its de-rived strains may contain resistance genes Bph15. |
