Effects of RHT-B1bE529K on stem elongation. a Representative BC1F3 plants carrying homozygous RHT-B1b, heterozygous, and homozygous RHT-B1bE529K alleles. b, c Internodes length of homozygous RHT-B1b (Wild), heterozygous (Het), and homozygous RHT-B1bE529K plants (Mut) in F2 and BC1F2 populations, respectively. Different letters (a, b, and c) indicate significant differences in a Tukey’s multiple comparison test at P < 0.05
