发明名称 Pear tree Old HomexFarmingdale variety No. 87
摘要 This invention relates to a new and distinct variety of pear tree which is useful as a size-controlling rootstock. The new variety originated as a single seedling selected from a large group of pear seedlings which were grown from open-pollinated seed. This seed was collected from Old Home Pear Trees (Pyrus communis) growing in an isolated planting with Farmingdale pollinizers. Pear fruiting varieties propagated on the under stock of this new rootstock variety are approximately 80% of the size of like pear trees growing on domestic Bartlett seedling rootstocks. This "semi-dwarfing" selection is easily asexually reproduced; particularly by hardwood cuttings. It has proven to be graft compatible with all commercially grown pear varieties. It was selected for its non-rootsuckering habit, its resistance to Fireblight disease and its tolerance of Pear Decline disease. It has also proven to be hardy, early bearing and well anchored in the many areas and soil types where it was tested. It has proven to be adaptable to Northern pear growing areas such as Summerland, British Columbia, Harrow, Ontario, and Kentsville, Nova Scotia, Canada, having been selected to fill these Northern pear growing rootstock needs.
