The phenotype comparison among IR64, NIL-S68 and hybrid F1. (a–c) The plant architecture exhibits no significant differences among IR64 (a), F1 (b) and NIL-S68 (c). Scale bar, 10 cm. (d–f) Pollen fertility of IR64 (d), F1 (e) and NIL-S68 (f). The green arrows denote to normal pollen grains, the red arrows indicate the aborted pollen grains. Scale bar, 100 μm. (g) Quantitative analysis of pollen fertility and spikelet fertility. (h) Analysis of pollen germination rate of IR64, F1 and NIL-S68.
