One-half Wild Crab; one-half Siberian Crab 
This combination combines extreme hardiness with all-winter keeping, but the 
wild crab dominates in quality. More work should be done. 
Amsib Crab - Introduced 1952. Female parent: Wild Red, a form of Pyrus Ioensis 
from Iowa. Male parent: a Pyrus baccata brought by N. E. Hansen from Moscow, Russia, 
in 1906. The name "Amsib” is condensed from the names America and Siberia. A good 
sized crab, about 13/4 inches in diameter, green and yellow, keeps all winter, with 
fragrant wild crab flesh but neutral rather than bitter. It is only an ornamental 
tree at present, but it is the first hybrid of the indigenous American apple with the 
Siberian crab and has possibilities for the future. Scions, 50 cents per foot. 
A Siberian Crab With Smooth Basin 
Beauty Crab - Introduced in 1919. Seedling of Pyrus baccate cerssifera raised 
here from seed received from the Botanical Gardens at Leningrad. Fruit a brilliant 
solid cherry red with orange red underneath; calyx segments deciduous with no opening 
into the core at the basin or blossom end. A tree of Beauty crab or Siberian crab 
stock bore ten bushels one year here at Brookings. Tree 100% hardy at Morden, Mani¬ 
toba. Many seeds from a bushel of fruit; the resulting seedlings are excellent for 
budding and grafting. The trees are ornamental also. Scions of Beauty crab, 25 cents 
per foot. 
New or Rare Apples 
The following are available as 1 or 2 year root-grafts on Siberian crab stocks. 
See descriptions in S. D. Bulletin 224 and 309. Number available at 25 cents each: 
Bison crab 5; Yellow Sweet apple 20; Zelma crab 5; Caramel apple 18; Olga crab 88 ; 
Goldo apple 101; New Duchess apple from Ivan V. Michurin (Soviet Union) Russia, 30.

Seedlings of Chang pear (S. D. Bulletin 224) top-

John Robertson orchard, Hot Springs, South Dakota.

As discussed in S. D. Bulletin 224, commercial Pyrus Ussuriensis stocks axe not 
hardy enough at this station but are hardy further south; at the North careful mulch¬ 
ing would be necessary. By planting deep enough, the hardy top wmld soon be on its 
own roots. 
S, D. Valya Pear - Offered for the first time. Pedigree: Lincoln pear x Russian 
Sand pear pollen. The reciprocal hybrid of the Sladky, introduced in 1933. Fruit 
nearly two inches across, round tapering to stem, yellow with minute russet dots* 
Good quality. A good tree, no blight, bore a heavy crop in the drouth year 1936. 
Scions, 50 cents per foot. 
Pear Stock Experiments 
Dwarf pears are on quince stocks and are widely grown in pear-growing regions 
wherever the quince stock is hardy. This is because they bear very much earlier than 
standard pears, which are pears on pear stocks. This subject was discussed in my pa¬ 
per "Fruit Stocks Where the Mercury Freezes", at the Ninth International Horticultural 
Congress in London, August 1930. In this paper I suggested the use of Cotoneaster 
acutifolia, a choice Siberian ornamental shrub used for hedges and in the border, as 
a dwarf stock for pears. For spring 1938 permanent planting, a few Harbin pears bud¬ 
ded on Cotoneaster acutifolia stocks can be spared for trial elsewhere, dwarf trees 
2 to 4 feet in height. Price per tree, 50 cents. The trees are greatly dwarfed and 
should bear very early, provided the root proves strong enough to sustain the pear top.
