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 experimental objective was to select from this seedling population, rootstock clones which would root readily by vegative means.
- the most major additional objective was to determine and select a series of growth-controlling rootstock clones which would permit orchardists to develop plantings using tree spacing techniques tailored to known uniform tree sizes.
- Old Home ⁇ Farmingdale #40 has shown its usefulness by exhibiting the following charcteristics which fulfill all of the original desired objectives. It has been chosen as the best of several "dwarfing" selections after nearly 30 years of orchard and nursery testing and evaluation.
- Pear varieties grown on the rootstock of this variety are approximately 65% of the size of like pear trees grown on the most commonly used commercial pear rootstocks used in the trade. These are seedling rootstocks grown from 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.
- Rootstocks of this new variety are almost completely resistant to Fireblight infection whereas domestic Bartlett seedling rootstocks are shown to be highly susceptible.
- This new clonal rootstock is believed to be Pear Decline tolerant. No Pear Decline symptoms were noted on trees grafted to this rootstock throughout the many years of testing and evaluation in the several plots where tests were conducted. In comparison, Decline symptoms were noted on trees grafted to Domestic Bartlett seedlings as well as on trees grafted to several other seedling rootstock types being evaluated.
- the new pear rootstock clone has been virus-indexed and found to be free of all known virus diseases of pear.
- Yield efficiency (comparing yield to unit of tree size) was rated about 6% above that of trees on Domestic Bartlett seedling rootstocks.
- This rootstock selection is hardy in all areas where it was tested and is considered to be hardy wherever pears are grown.
- the new rootstock is graft-compatible with all major commercially grown pear varieties.
- Pear rootstock trees of the Old Home ⁇ Farmingdale #40 variety can be easily propagated by hardwood and softwood cuttings and/or by micropropagation methods (meristematic tissue culture). Such asexual reproductions have demonstrated that its distinctive characteristics and particularly including its "dwarfing" character are stable and are transmitted without change through succeeding propagations and generations.
- FIG. 1 A first figure.
- This picture shows a one-year old shoot of Old Home ⁇ Farmingdale #40 taken from the cuttingbed showing its straight, upright and branchless habit of growth.
- This picture shows typical leaves of Old Home ⁇ Farmingdale #40 showing their broad-ovate shape and finely-serrated margins. The rather short, stubby petioles are shown here with the long slender stipules at the base.
- This picture shows a rooted hardwood cutting of Old Home ⁇ Farmingdale #40 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 --Broad-elliptic, ovate.
- Shape --Wide, turbinate, inclined to truncate.
- Size control potential "Dwarf", about 65% of standard, less vigorous varieties more reduced in size.
- Compatability Graft-compatible with all major commercial fruiting varieties.
- Rooting Hardwood cuttings root well, roots arise mostly at basal cuts.
- Root anchorage Good in all soil types tested.
- Hardiness Hardy wherever pears are grown.
- Pest resistance Average resistance to common pests of year.
