Abstract
A new and distinct cultivar of black walnut tree (Juglans nigra L.) which is distinctly characterized by extremely rapid growth rate, fair central stem tendency, earlier than average time of leafing, and average straightness thereby producing good timber qualities. The new variety has outstanding nut qualities as well, such as abundant annual crops of large-sized nuts, begins nut-bearing early in life of tree, average 2 nuts per cluster, and produces kernels which exceed about seventeen (17) percent of nut weight. The nuts are large and ripen early. The pistillate flowers mature early while pollen maturity is mid-season. In most years there is no overlap in female and male flowering. Flowering begins very early in the life of the tree. This new variety of black walnut tree was discovered by the applicant near Fritchton in Knox County, Ind., in a cultivated area. It occurred as a wild tree growing on land managed for timber-growing purposes and was discovered in the course of a search for unique and high quality black walnut trees to be utilized in breeding for outstanding timber producing potential. This selection has been designated as BW48 in records maintained on the performance of grafts made from the original selection and will be known henceforth as Knox-1.
Description
FIG. 1 is a photograph showing the timber form of Knox-1.
FIG. 2 is a photograph showing a twig with nuts attached from Knox-1.
FIG. 3 is a photograph showing leaves from Knox-1.
After the original clone was selected, and assigned an identity number of BW48, the aforesaid tree was reproduced by collecting scions from it and grafting these onto common black walnut rootstocks at Martell Forest, Purdue University. These asexual reproductions ran true to the parent tree and to each other in all respects.

Anthracnose resistance.--Better than average on a rating scale of 1 to 5.
Time of leafing.--Very early -- averages 5 to 6 days earlier or 54% earlier than average.
Flowering habit:
Age at which tree starts producing catkins.--Very early.
Number of catkins produced.--Abundant.
Size of catkins.--Large.
Time of pollen shed.--Average.
Age at which time tree starts producing pistillate flowers.--Very early.
Number of pistillate flowers produced by young tree.--Abundant.
Number of pistillate flowers produced by mature tree.--Abundant.
Lateral shoots producing pistillate flowers.--Few.
Number of pistillate flowers per inflorescence.--Averages 2 to 3.
Timing of pistillate flower receptivity.--Very early.
Coincidence of staminate and pistillate bloom.--Seldom.
Nut crop:
Bearing.--Annual.
Productivity.--Heavy.
Ripening period.--Early.
Evenness of maturity (period between first and last nuts are ready for harvest).--Even.
Quality.--Very good.
Distribution of nuts on tree.--Throughout.
Hull:
Outer surface.--Smooth -- waxy.
Form.--Slightly pointed both ends -- pear shape.
Thickness.--Medium.
Size.--Medium to large; average length -- 2 7/16"; average diameter in suture plane -- 1 15/16"; average diameter cheek to cheek -- 2 3/32".
Nut:
Size.--Large; average length -- 11/2"; average diameter in suture plane -- 1 7/32"; average diameter cheek to cheek -- 1 7/16".

Blossom end.--Rounded.
Basal end.--Pointed.
Weight.--Dry weight of ten nuts -- 173.8 gm; dry weight of ten kernels -- 29.6 gm; average percentage of kernels to nuts -- 17%.
Thickness of shell.--Medium.
Fill.--Good.
Kernel:
Size.--Large.
Plumpness.--Plump.
Shrivel.--None.
Flavor.--Good.
Color.--Light.
