with LOD score of 2.57 and 4.47% of PVE; and the
major QTL namely qSBPH12-a1, was detected in location
between RM519 and RM3331 on the long-arm of
chromosome 12, with a high LOD score of 18.99 and
it explained 37.84% of the phenotypic variance in F2
population. As indicated by the additive effect, resistant
alleles at qSBPH1-a, qSBPH2-a, qSBPH4-a, qSBPH12-a2
and qSBPH12-a1 came from ‘Rathu Heenati’ (Table 4).
