Fig. 5From: Hybridity has a greater effect than paternal genome dosage on heterosis in sugar beet (Beta vulgaris)Sugar beet fruit and seed characteristics of F1 triploid hybrids and their parent lines. Data are mean of four replicates (± SD). a Seed viability, b seed size, c embryo size, d perisperm size. Different genotypes specified in parentheses. * Best parent heterosis (P ≤ 0.05), †Mid-parent heterosis (P ≤ 0.05), NS Not significantly different (P > 0.05), ‡ Below mid-parent value (P ≤ 0.05)Back to article page
