The SSR marker MS5 (primer sequences F: 5′- TTGTGGGTCCTCATCTCCTC-3′, R: 5′-TGACAACTTGTGCAAGATCAAA-3′) linked to Bph15 (Yang et al. 2004) and the InDel marker InD4 (primer sequences F: 5′-AGAATGCTAAAGATGACTGAA-3′, R: 5′-AACGGTATTGTTCTTGTCTAA-3′), which was more tightly linked to Bph15 (Lv et al. 2014), were used to select individual positive plants in each generation.
