Excess ferrous iron in lowland soil is known to inhibit the growth of rice. A quantitative trait locus (QTL) analysis for susceptibility was performed using chromosomal segments substitution lines (CSSLs). Kasalath, an indica rice cultivar, be susceptible and accumulate excess shoots. The shoot concentration examined 39 CSSLs carrying Kasalath a background Koshihikari, japonica cultivar. grown hydroponic culture solution containing iron, had higher than Koshihikari. Of CSSLs, SL208, which carries segment on chromosome 3, significantly none lower This finding suggests that putative QTL affecting between markers R663 S1571 3.
