Fig. 4From: Identification of Novel Quantitative Trait Loci for Culm Thickness of Rice Derived from Strong-Culm Landrace in Japan, OmachiComparison of the culm traits of the RILs classified on the basis of allele combinations. White and black arrows indicate the trait values of Koshihikari and Omachi, respectively. In boxplots, different letters indicate significant differences at p < 0.05 (Tukey’s test). The number under each boxplot indicates the number of RILs classified into the groupBack to article page
