Complete diallel crosses were made among three parental peanut (Arachis hypogaea L.) genotypes to gain a better understanding of photosynthetic inheritance. Highly controlled environmental conditions were used throughout the study to determine apparent photosynthetic rates. Results indicated significant differences among parents and F1 hybrids. Reciprocal differences were also observed between certain cross combinations. Dominance and overdominance effects were found under these test regimes which suggest a heterotic response for this important characteristic.
