AC™ Harrow Crisp Pear on Quince Provence (Spring 2024)
A modern, self-fertile, fireblight-resistant pear from Canada. Also known as HW610, Harrow Crisp.
AC™ Harrow Crisp is a midsized, conical, upright, annually productive, and hardy tree. More importantly, it is fireblight resistant, making it a great choice for home orchardists and organic growers. AC™ Harrow Crisp does not produce sufficient viable pollen to be used as a pollenizer for Barlett. However, it is self-fertile. AC™ Harrow Crisp will pollinate Bosc, Flemish Beauty, and Anjou.
The fruit is a very attractive pear, blushed red on smooth yellow skin, slightly larger than Bartlett, with fine and firm cream-white flesh. The flavor is mild and sweet, and it receives very high ratings in taste trials. AC™ Harrow Crisp matures at the end of August or early September, about the same time as Bartlett, and it can be picked over a two-week period. Early picked fruit can be stored for about two months, but storage life is reduced with later picking. If kept too long or picked too late, it will deteriorate internally without external signs. When processed as pear halves, it maintains its integrity.
This cultivar originated from a 1972 cross of Bartlett and US56112-146 made by H. A. Quamme at Harrow, Canada. The selection was made in 1979. The parentage of the breeding selection US56112-146 includes Barseck, which imparts disease resistance to many modern pear cultivars.
