Substituted mapping of qPGC11 for grain chalkiness. a, The head rice appearance of the HJX74 and HP67–11. Scale bar: 1 cm. b, Substitution mapping of qPGC11. The positions of substitution segments and the PGC of HP67–11 and its NILs are shown, with HJX74 as the control. The numbers under the chromosome are physical distance (Mb). White and black blocks represent the homozygous genotypes of HJX74 and HP67–11, respectively. c, PGC effects of three genotypes of qPGC11 in an F₂ population. qpgc11/qpgc11 represents homozygous genotype of HJX74 (n = 26); qPGC11/qpgc11 represents heterozygous genotype of HJX74/HP67–11 (n = 49); qPGC11/qPGC11 represents homozygous genotype of HP67–11 (n = 30). Significance analysis in b and c was by one-way ANOVA, Duncan, two-tailed. Values in the lines among different letters are different at 1% level of significance
