Origin: in Beltsville, Md., by U.S. Dept. of Agriculture. Introd. for trial in 1960. Released in 1968 by H.J. Brooks. Seckel seedling × Comice; tested as US 3866-E. Tree: very vigorous and spreading for a pear; original tree and first trees propagated from it have some thorns, which may be expected to decrease with additional repropagations; begins bearing at about 6 years; early fruiting mainly on mediumlong terminals; entirely pollen-sterile, but sets well with all varieties that have been tested; very resistant to fire blight. Recommended for general trial because of high degree of apparent blight resistance and high quality of fruit. Named in honor of John R. Magness who retired in 1959 as chief of the fruit and nut crops section at U.S. Dept. of Agriculture, Agricultural Research Center, in Beltsville, Md. Fruit: size medium; oval; skin lightly covered with russet, relatively tough, somewhat resistant to insect puncture and decay; flesh soft, very juicy, almost free of grit cells, flavor sweet, highly perfumed, aromatic; ripens at Beltsville about 1 Sept., being a week later than Bartlett; ripens for prime eating in about 10 days when held at 70F; can be held in cold storage up to 3 months, then ripens with good quality.
