Precise location of the identified QTL region and candidate QTL for the traits of anther color and hull color. a QTL region associated with anther color (AC) was located on Chr6 and its additive effect; b QTL region associated with hull color (HC) was located on Chr1 and its additive effect; c precise location of qAC1 and qAC2 and bin-marker distribution in QTL region on Chr6; d precise location of qHC1, qHC2, and qHC3 and bin-marker distribution in QTL region on Chr1. In (c) and (d), the blue line with blue circular dot represents the LOD distribution, the dark line with blue square dot represents the distribution of bin markers according to the genetic positions, and the dark line with red diamond represents the distribution of bin markers according to the physical positions. The scale of the physical distance is shown in the upper right corner. The recombination bins near the LOD peaks of the QTL are illustrated and linked with colored blocks. Relevant information is also shown in the figure. AE, additive effect.
