From: Mapping a quantitative trait locus for resistance to bacterial grain rot in rice
BGR resistance of backcrossed inbred lines (BILs) derived from a cross between Kele and Hitomebore. Frequency distributions of (A) the ratio of diseased spikelets (RDS) and (B) the ratio of diseased spikelet area (RDSA) assessed by the modified method of cut-panicle inoculation, classified by the genotype for marker P0684. White and black bars represent lines homozygous for the Hitomebore and Kele alleles, respectively. One line was found to be heterozygous at P0684 and is not shown. Arrows indicate the mean values of Kele and Hitomebore. Horizontal lines under the arrows indicate the standard deviations.
