Tyson competes with Clapp Favorite as the precursor of the pear season which is really opened by Bartlett. In every character of fruit and tree excepting size and color of fruit, Tyson excels Clapp Favorite. The quality of the fruit far excels that of Clapp Favorite and is better than that of Bartlett. Indeed, of commonly grown pears, the characters of flesh and flavor are second only to those of the fruits of Seckel. The flesh is melting and juicy, with a spicy, scented sweetness that gives the fruit the charm of individuality. The pears keep longer and ship better than those of Clapp Favorite; their season in New York is from the middle of August to the middle of September. Unfortunately, the pears are but medium in size, and are often poorly colored, both of which defects appear on the fruits of this variety as grown on the grounds of this Station and shown in the accomanying illustration. The tree is the most nearly perfect of that of any pear grown in America-the Kieffer, praiseworthy only in its tree, not excepted. The tree is certainly as hardy as that of any other variety, if not hardier, and resists better than that of any other sort the black scourge of blight. Add to these notable characters large size, great vigor, and fruitfulness, and it is seen that the trees are nearly flawless. The only fault is, and this is a comparatively trifling one, that the trees are slow in coming in bearing. Tyson is the best pear of its season for the home orchard, and has much merit for commercial orchards. Were the fruits larger, it would rival Bartlett for the markets. No other variety offers so many good starting points for the pear-breeder.
Tyson originated as a wilding found about 1794 in a hedge on the land of Jonathan Tyson, Jenkintown, Penn. The tree first bore fruit in 1800. The pears proved to be so good that Mr. Tyson distributed cions among his neighbors, but the variety was not generally disseminated. About 1837, a Doctor Mease of Philadelphia sent cions to B. V. French, Braintree, near Boston, who in turn distributed them among his friends. The variety fruited here about 1842, and the fruit was exhibited before the Massachusetts Horticultural Society under the name Tyson. In 1848, at the National Convention of Fruit Growers, Tyson was recommended for general cultivation, and since that date the name has appeared continuously in the catalogs of the American Pomological Society.
Tree very large, vigorous, upright-spreading, tall, dense-topped, hardy, productive; trunk very stocky, rough; branches thick, dull reddish-brown, overspread with gray scarf-skin, with few lenticels; branchlets slender, short, light brown mingled with green, smooth, glabrous, sprinkled with few small, inconspicuous lenticels. Leaf-buds small, short, conical, pointed, plump, appressed or free. Leaves 22, in. long, 11 in. wide, thin; apex abruptly pointed; margin finely and shallowly serrate; petiole 5, in. long. Flower-buds small, short, conical, pointed, plump, free, singly on short spurs; flowers medium in season of bloom. Fruit matures in late August; medium in size, 2 .1 in. long, 1 in. wide, roundish-acute-pyriform, with unequal sides; stem 13 in. long, curved; cavity very shallow, obtuse, round, usually drawing up as a lip about the base of the stem; calyx open, small, lobes separated at the base, short, narrow, acute; basin shallow, narrow, flaring, slightly furrowed, compressed; skin tough, smooth, slightly russeted, dull; color deep yellow, usually blushed; dots numerous, very small, obscure; flesh tinged with yellow, granular around the basin, otherwise rather fine-grained, tender and melting, very juicy, sweet, aromatic; quality very good. Core small, closed, with clasping core-lines; calyx-tube, short, wide, conical, seeds medium in size and width, plump, acute. The flesh is melting and Juicy, with a spicy, scented sweetness that gives the fruit the charm of individuality. -- U.P. Hedrick, The Pears of New York, 1921.
