Pollen fertility of HJX74, SSSL-S23, HJX74/SSSL-S23 F1 and F2 populations. Spikelets (left) and pollen grains (right) in HJX74 (a in NSD), SSSL-S23 (b in NSD) and HJX74/SSSL-S23 F1 (c in NSD and d in NLD) plants. Arrow indicated the aborted pollen grain. Scale bars, 1 mm for spikelet and 100 μm for pollen. e A bimodal distribution for pollen fertility detected in 200 F2 plants derived from the cross between HJX74 and SSSL-S23 in NSD. Arrows indicated the mean pollen fertility of HJX74, SSSL-S23 and HJX74/SSSL-S23 F1 plants, respectively
