Narrative

Discovered as a sport of Williams Bon Chretien in an orchard in the western Cape Region of South Africa. Possibly near the Ceres growing region. Lower chilling requirement and earlier ripening than standard Bartlett. Also known as Early Bon Chretien or EBC in South Africa. -- Taaibos Human, personal communication at 9th International Pear Symposium, Stellenbosch, South Africa, February, 2004.

High quality medium sized pear imported from South Africa's Pear Research Station to Texas by Herb Durant (local blueberry hybridizer) in early 1980s. Lower chill (about 550 - 600 hours) than standard Bartlett and less blight sensitive for humid climates. Bears well in Houston where standard Bartlett fails.
