kyIR9 [X: ~4745910 - ~4927296, N2>CB4856] X. LG X contains N2 from ~4745910 - ~4927296; the rest is from CB4856. QX9 was crossed to CB4856; a recombinant F2 with N2 npr-1 and CB4856 tyra-3 was isolated. Its progeny was back-crossed to CB4856 8 times, picking npr-1 hets each round prior to homozygosing.
