Heterosis of Apparent Photosynthesis Rate in Arachis hypogaea L.¹

Authors: W. D. Branch , J. E. Pallas

Abstract

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.
