Substitution segments and detected QTLs in Z749. Physical distances (Mb) and mapped QTLs are marked at the left of each chromosome; markers and substitution length (black arrow direction) are displayed to the right of each chromosome. PL: panicle length, NPB: number of primary branches, NSB: number of secondary branches, SPP: spikelet number per panicle, SSD: seed-set density
