Mycorrhizal fungal colonization (percent root length colonized) in the roots of O. sativa at 6, 9, and 12 weeks after inoculation. Black bars represent colonization by parental lines and white bars by crossed lines, originating from crosses between C3 and D1. Error bars indicate ± 1 standard error (SE). Bars topped by different letters within each harvest are significantly different at P ≤ 0.05. The following numbers of samples were taken at 6 weeks: NM, 12; C3, 8; D1, 11; Sb, 6; Sc2, 8; and Sd, 5. The following numbers of samples were taken at 9 weeks: NM, 12, C3, 11; D1, 12; Sb, 12; Sc2, 12; and Sd, 10. The following numbers of samples were taken at 12 weeks: NM, 12, C3, 7; D1, 9; Sb, 10; Sc2, 8; and Sd, 8.
