Definitions
- the original plant of this new variety was a member of a family of over 2000 pear seedlings which germinated from seed obtained from the Canadian Department of Agriculture Research Unit located near Summerland, British Columbia, Canada. This seed, collected from open-pollinated Old Home pear trees (Pyrus communis) which were growing in an isolated experimental planting with Farmingdale pollinizers, was planted by the inventor in his nursery at Forest Grove, Oreg. in 1952.
- Another objective of this work was to select from the seedling population, rootstock clones which would root readily in the nursery by cuttings and/or by other vegetative means.
- the most major additional objective was to select from this seedling population a series of growth-controlling rootstock clones which could be made available to nurserymen and growers and which would permit them to develop orchards using tree spacing techniques tailored to known uniform tree sizes.
- This objective can be accomplished only through the use of clonally propagated rootstocks.
- Old Home x Farmingdale #69 has shown its usefulness by exhibiting the following characteristics which fulfill all of the original desired objectives. It has been chosen as the best of several "semi-dwarfing" selections after nearly 30 years of orchard and nursery testing and evaluation.
- Pear varieties grown on the rootstock of this variety are approximately 75% of the size of like pear trees grown on the most commonly used commercial pear rootstocks used in the trade. These are seedling rootstocks of Domestic Bartlett seed also known as Domestic pear seedlings (Pyrus communis). Trees grown on Bartlett seedling rootstocks are considered "standard” in size when established in the orchard and are used as the basis for all of the comparisons and measurements herein.
- the new pear rootstock clone has been virus-indexed and found to be free of all known virus diseases of pear.
- Trees on this clone have been rigidly inspected in the orchard for rootsuckering. Less than 1% of the trees observed on this rootstock, showed a tendency to rootsucker when tested over a 20 year period.
- Yield efficiency in tests run to date, has been about equal to trees on Bartlett seedling rootstocks. Yield efficiency was determined by comparing yield to unit of tree size.
- the new rootstock selection has proven to be hardy in all areas where it was tested and is considered to be hardy wherever pears are grown.
- This new and distinct rootstock is graft-compatible with all commercially grown pear varieties.
- the new selection shows only average resistance to Pear Root-aphids.
- Pear rootstock trees of the Old Home x Farmingdale #69 variety can be easily propagated by hardwood and softwood cuttings and/or micropropagation methods (meristematic tissue culture). Such asexual reproductions have demonstrated that its distinctive characteristics and particularly including its "semi-dwarfing" character are stable and are transmitted without change through succeeding propagations and generations.
- Old Home x Farmingdale #69 is a variety intended to be used only as a rootstock for pear cultivars, the main detailed description and accompanying drawings will center on the vegetative parts rather than the flowers and fruits. This pear selection will be propagated only asexually rather than by seed, in order to maintain its clone characteristics. The accompanying pictures show typical specimens of this new clonal pear rootstock.
- FIG. 1 A first figure.
- This picture shows a one-year old shoot of Old Home x Farmingdale #69 taken from the cuttingbed showing its semi-spurry habit of growth, its straight upright stem and its slightly rolled leaves.
- This picture shows typical leaves of Old Home x Farmingdale #69 showing the finely-serrated margins.
- the long slender petiole is slightly channeled and is shown here with the long, narrow stipules at the base.
- This picture shows typical pyriform shaped fruit of Old Home x Farmingdale #69.
- This picture shows a seven year old Bartlett tree on a Old Home x Farmingdale #69 rootstock.
- This picture shows a seven year old Bartlett tree on the "standard” and commonly used Domestic Bartlett seedling rootstock.
- This picture shows a rooted hardwood cutting of Old Home x Farmingdale #69 taken from the cuttingbed showing typical root development at the basal cut.
- Colors of leaves and shoots herein described are based on their appearance at the site where stocks were grown, dug and stored. In those instances where a precise color assessment can be made, reference is to a Munsell Limit Color Cascade chart. In other instances, general color terms are used in accordance with their ordinary dictionary significance.
- Shape --Short, obtuse, pointed, conical.
- Size control potential "Semi-dwarf”, about 75% of standard, less vigorous varieties more reduced in size.
- Compatibility Graft-compatible with all major commercial fruiting varieties.
- Rooting Reproduces well by hardwood cuttings, roots arise mostly at basal cut.
- Hardiness Hardy wherever pears are grown.
- Pest resistance Average resistance to common pests of pear.
