Fig. 2From: Hybridity has a greater effect than paternal genome dosage on heterosis in sugar beet (Beta vulgaris)Sugar beet seed characteristics of diploid and triploid F1 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. DH = double haploid. * Best parent heterosis (P ≤ 0.05), †Mid-parent heterosis (P ≤ 0.05), NS Not significantly different (P > 0.05)Back to article page
