[0024] The detailed description of the present invention is as follows:
[0025] Studies have shown that there is a major gene locus that controls the stable expression of stripe leaf blight resistance at the same position on rice chromosome 11. Maeda H et al. (1999) used the Miryang 23 / Qiuguang recombinant inbred line population to detect a QTL for resistance to stripe leaf blight near XNpb257 between markers XNpb202 and C1172 on chromosome 11, with a contribution rate of 17.36%. The resistance gene effect comes from Miryang 23; Hayano-Saito et al. (1998) used the F obtained by crossing the resistant progeny Asanohikari of Modan with the susceptible japonica rice Koshihikari 2 The population will be derived from the stripe leaf blight resistance gene Stv-b of indica rice Modan i Located between the XNpb220 and XNpb257 markers on chromosome 11. Our research group has used the Kinmaze (japonica) / DV85 (indica) recombinant inbred line population to detect qStv11, which comes fr...
