Narrative

Daves's Delight (PI 617564).-An early season, attractive, very high quality pear, which stores well for its season and is relatively free of core breakdown. Originated at Kentville, Nova Scotia, by A.D. Crowe, Agriculture Canada Research Station. Beierschmidt x Bartlett. Released in 1986. Fruit: medium to below medium; pyriform, slightly irregular to ribbed; stem fairly long, inserted at a slight angle;basin small, shallow, calyx closed; skin yellow (#11A, R.H.S. 1986 ed.), up to 50% washed with attractive bright red (#40B, R.H.S. 1986 ed.); many inconspicuous lenticels, light russet near stem; core medium-small, closed;; flesh light cream, very fine and buttery, nearly free of grit cells; flavor aromatic, equal to or better than Bartlett. Early maturing, with Buerre Giffard; holds well on or off tree with good resistance to core breakdown. Tree: vigor moderate; appears cold hardy; relatively precocious and productive. Released as a dessert pear; processing qualities not known. Not tested for processing but should equal Bartlett quality. -- Brooks and Olmo Register of Fruit and Nut Varieties
