Phenotypic Characterization of Hybrid Weakness in Rice Plants.
(A, B) The morphology of NIL(hwi1) and NIL(Hwi1) at the seedling stage (A) and the heading stage (B).
CPhenotypic evaluations of yield-related traits of NIL(hwi1) and NIL(Hwi1). Twenty independent individuals were evaluated for quantification. ** P ≤ 0.01; ns, no significance. Scale bar = 10cm in (A) and (B).

Fine Mapping of the Hwi1 Gene (A–D) and the Expression of Candidate Genes (E, F).
ALinkage map of the wild rice chromosome substitution region (shown by the solid black bar) on chromosome 11. The Hwi1 gene was delimited between flanking markers RM26153 and RM Numbers shown between adjacent markers indicate the genetic distance in cM.
(B, C) Fine mapping of the Hwi1 gene. Numbers under each marker indicate the number of recombinants between the marker and the Hwi1 gene. Scale bars of the physical maps are 10 kb in (B) and 2 kb in (C).
The Hwi1 gene was localized to the region defined by CAPS56 and M4 and two candidate genes, LOC_Os11g07230 and LOC_Os11g07240, within this region are shown in (D). The expression level of LOC_Os11g07230 (E) and LOC_Os11g07240 (F) in the basal nodes of NIL(hwi1) and NIL(Hwi1) as determined by real-time PCR.
