Table 3 A. Mean values for AR1 mycelial mass and peramine concentration (± SE), in T₂ progeny segregating for DGAT + CO grown either in a growth chamber or in the field. B. Mean values for AR37 mycelial mass and total epoxyjanthitrem concentration (± SE), by zygosity of the DGAT + CO trait in T₂ segregating progeny grown in the field. Bars represent means ± SE. Letters A and B indicate a significant difference at P < 0.05 comparing DGAT + CO hemizygous, homozygous, or null progeny
