Chromosome substitution segments of Z414. Physical distances (Mb) and mapped QTL are indicated on the left; markers and substitution segment lengths are shown on the right. The black sections on each chromosome are substitution segments. PL, panicle length; GW, grain width; GL, grain length; RLW, ratio of length to width; GWT, 1000-grain weight; BRR, brown rice rate
