From: Substitution Mapping of Two Closely Linked QTLs on Chromosome 8 Controlling Grain Chalkiness in Rice
Substitution mapping of qPGC8.2 for grain chalkiness. a The milled rice of the HJX74 and SSSL 03-08. Scale bar: 1 cm. b Substitution mapping of qPGC8.2. The positions of substitution segments and the percentage of grain chalkiness (PGC) of 03-08 and its NILs are shown. The numbers under the chromosome indicate physical distance (Mb). White and black blocks represent the homozygous genotypes of HJX74 and 03-08, respectively. PGC (%) was the mean ± S.E. in two cropping seasons. c PGC of three genotypes of qPGC8.2 in an F2 population. qpgc8.2/qpgc8.2 represents homozygous genotype of HJX74 (n = 23); qPGC8.2/qpgc8.2 represents heterozygous genotype of HJX74/03-08 (n = 47); qPGC8.2/qPGC8.2 represents homozygous genotype of 03-08 (n = 30). d Grain length of 03-08 and its NILs. e Grain width of 03-08 and its NILs. Values in the lines among different letters are different at 1% level of significance in b and at 5% level of significance in c–e
