Fig.2. Phenotype of three ZmMs7 transgenic maize male-sterile maintainer lines (BC2F1)(a), (c) and (e) Ear photos of the three male-sterile maintainer lines (1601#, 1602# and 1603#) under bright light (BL) (b), (d) and (f) The ear photos corresponding to (a), (c) and (e) Under a red fluorescence (RF) filter, respectively. These lines are the BC2F1 progeny of the elite line M0701-2 crossed with ms7-6007 mutant and then backcrossed to inbred line Zheng58. BC2F1 is the second backcross generation. Bars = 1cm
