Genetic analysis of new genes for resistance to brown planthopper in rice mutants

Abstract

Rice breeding using induced mutation has succesfully produced several mutant lines resistant to brown planthopper. In order to beable to utilize these mutant lines further in a breeding programme it is essential to study the inheritance of resistance to brown planthopper in rice mutants MG-8 and MG-18 was studied in the Center For Application of Isotope and Radiation. Pasar Jumat. The result showed that the resistance of MG-8 and MG-18 to brown plathopper was controlled by a single recessive gene and this gene is not allelic to bph-2 of the ASD-7 genotype.
