Another QTL conferring antixenosis against SBPH,
qSBPH2-b2 was mapped at the region between RM318-
RM240 on chromosome 2 by 150 BC1F2 lines, with LOD
score of 2.28 and 6.6% of the phenotypic variance in this
population, but indicated by the additive effect, resistant
alleles at qSBPH2-b2 did not come from Rathu Heenati,
but came from 02428 (Table 5, Fig. 3).
