| Abstract: | Male sterile line is one of the most important parents of hybrid rice.Selecting the blast-resistance sterile line with excellent integrated characters is one of the most important tasks now.The Indica CMS Line Guang-kang13A shows relatively strong and wide resistance spectrum in production.In October,2003,it was technically identified in Fujian Province.The composition of blast resistance genes at Guang-kang13A were identified in the genetic background of five near-isogeneic lines with CO39 as the parents(Differential varieties) and one susceptible comparison LTH.The populations of F1,F2 from the cross of resistant sterile line Guang-kang13A and universally susceptible variety LTH were inoculated by spraying with four stable virulence strains of Guy11,FJ2009-66,98013A and 98099 in seedling stages.The results of resistance genetic analysis showed that there was one dominant gene in Guang-kang13A in responsible for resistance to four strains.The allelic test indicated that the gene with resistance to 98013A is non-allelic to loci of Pi-2 and the gene with resistance to Guy11 is linkage inheritance to loci of Pi-4b.Based on the results in resistance response,it is suggested that the two genes of Guang-kang13A are not Pi-1,Pi-4a and Pi-3.It is necessary to confirm whether there are two unknown genes. |
