Abstract

A new and distinct variety of plum tree which is of medium to large size, vigorous, upright in growth, and a productive and regular bearer of large, firm, yellow flesh, clingstone fruit having a high degree of red skin color. The fruit is further characterized by relative uniform ripening throughout the tree, holding firm on the tree for 7-10 days after picking ripe, having good eating, shipping and storage quality.

Description

ORIGIN OF THE VARIETY

The present variety of plum tree was originated by us in the experimental orchard located near Modesto, Calif. We selected it from a large number of seedlings which originated from a cross between a limb sport (which bore fruit with a higher degree of red skin color) of a Casselman Plum (Non-patented) and King David Plum (Non-patented). These seedlings which were planted and grown under careful observation by us, gave many and varying characteristics. One such seedling, which is the present variety, gave distinct and desirable characteristics and was selected for asexual reproduction and commercialization.

ASEXUAL REPRODUCTION OF THE VARIETY

The present variety of plum tree was asexually reproduced by budding in the experimental orchard located near Modesto, Calif. and shows that all characteristics come true to the original tree in all respects.

SUMMARY OF THE VARIETY

The new and distinct variety of plum tree which is medium to large, vigorous, upright in growth, and a regular and productive bearer of large, firm, yellow flesh, clingstone fruit ripening 7 to 10 days earlier than Casselman Plum (Non-patented); is further characterized in comparison by bearing fruit larger in size and with a higher degree of red skin color.

PHOTOGRAPHS OF THE VARIETY

The accompanying photographs show typical specimens of the foliage and fruit of my new plum variety, with the upper and lower surface of the leaves being illustrated and typical fruit specimens, an exterior and a sectional view being shown with a stone remaining in place. The illustrations were taken of the fruit shortly after being picked at maturity (firm ripe) and the colors are as nearly true as reasonably possible in a color representation of this type.

Claims

The following is claimed:

1. A new and distinct variety of plum tree, substantially as illustrated and described, which is a productive and regular bearer of large, yellow flesh, clingstone fruit with good eating, shipping and storage quality; the fruit is further characterized, in comparison to Casselman Plum (Non-patented) by ripening 7 to 10 days earlier, being larger in size and having a higher degree of red skin color.
