The RC is the percentage value between the 1100 Gy treated plants over the Control (0 Gy). Different lowercase letters marked in the same row represent significantly different among different γ-ray treatments. Different uppercase letters marked in the same column represent significantly different among different genotypes, (p < 0.05). Data are means ± standard deviation (n = 4 or 5)
