Clone from IR-2, Prosser, Washington. Prosser obtained from OSU Experiment Station, Talent (Medford), Oregon in 1970.Raised by Sam Packham of Molong, New South Wales about 1897. Now the leading pear in New South Wales and neighboring regions. Fruit medium or large in size, obtuse-pyriform. Surface somewhat rough, particularly on young trees, greenish-yellow or yellow in color, reasonably free of blemishes, fairly attractive. Flesh white, fine, melting, very juicy, quite free of grit. Sweet, vinous flavor, rates among the best in dessert quality. Season late, keeps as long as Beurre d'Anjou in cold storage. Holds up well after ripening. Tree moderately vigorous, spreading in habit, productive, fairly susceptible to pear scab and fire blight. Rapidly gaining ground as a commercial pear variety in this country and abroad. -- H. Hartman 1957.
