AC™ Harrow Sweet Pear on OHxF 87 (Spring 2026)
A high-quality, late-season modern pear that is fireblight resistant. Also known as HW609, Harrow Sweet.
This tree is medium sized, pyriform, upright-spreading, hardy, and reliably annual. It has great fireblight resistance and it is also resistant to mildew, but somewhat susceptible to scab. It is quite precocious: fruit is produced from lateral buds on one-year wood, as well as on spurs, thus coming into production in its second or third year. Fruit should be thinned to maintain size and productivity. AC™ Harrow Sweet has demonstrated pollen compatibility with Bartlett and Harrow Delight, and it will perform well on quince rootstock.
AC™ Harrow Sweet produces heavy crops that ripen three to four weeks after Bartlett. The pear is yellow with a red blush. The flesh is sweet and juicy, with an excellent flavor that rates highly in taste trials. It will store well for about ten weeks, and it holds its form when processed.
AC™ Harrow Sweet was developed from a cross of Bartlett x Purdue 80-51 (Old Home x Early Sweet). This same cross also produced Harrow Delight.
