'Mahan' (Nut photo) (Chestnut, Florida Giant, Georgia Giant, Masterpiece, Mayhan, Mississippi Giant) . Orig. as chance seedling from seed of unknown parentage planted about 1910 by J. M. Chestnutt. Propagation rights sold to F. A. Mahan, Monticello Nursery Co., Monticello, FL in 1927. Nut: oblong, with acute apex and base; nut often assymetric, appearing 'pinched' in middle due to flattening of abaxial and adaxial surfaces; flattened in cross section; 32 nuts/lb, 58% kernel; kernels with deep secondary dorsal grooves and basal cleft, often poorly filled to base, woody in texture. Homozygous for protogyny (PP) which is a dominant allele, making all 'Mahan' progeny protogynous. Mid- to late-season pollen shed, with early to mid-season receptivity. Very precocious and prolific, with a strong tendency to overbear as a mature tree. Ripens late, about 12 days after 'Stuart'. Very susceptible to scab. 'Mahan' is the female parent of 'Tejas', 'Kiowa', 'Harper', 'Mahan-Stuart' and 'Maramec' and the pollen parent of 'Choctaw', 'Wichita', and 'Mohawk'. Recommended (1990) for planting only in AR.
