Benefits of technology

"The patent text describes a new pawpaw variety called \"Levfiv\" that has exceptional quality and flavor. The fruits are large, firm, and have very few seeds. The skin is thicker and tougher than typical pawpaws, and the color is pale yellow-green. The fruits have a unique color break at the picking stage. The composition of the fruits is fleshy with fewer seeds and a pleasant aftertaste. The flavor is excellent, mild, and not objectionable. The pungent component that is unique to pawpaws is low. The leaves have a distinct rugosity, and the branching habit is widely spaced with wide crotch angles. The variety is susceptible to certain pests and diseases, but it responds well to pruning and grafting. The yield of fruits is moderate, and the variety may need to be grafted onto more vigorous rootstocks to promote good growth and heavier bearing."

Problems solved by technology

The pungent asiminous component that is uniquely pawpaw and that many people find objectionable is very low.
This variety is susceptible to Talponia plummeriana, the pawpaw peduncle moth, is susceptible to Eurytides marcellus, the zebra swallowtail butterfly, and is believed to be susceptible to pawpaw decline disease, the same in all cases as the species.

Abstract

Disclosed herein is a new and distinct variety of pawpaw tree, which has been given the name ‘Levfiv.’ This variety is distinguished by its all-around excellent fruit quality consisting of large, firm, fleshy, thick skinned fruits with an unusually low seed-to-fruit ratio and an excellent flavor. This variety possess the fleshiest and firmest fruit in pawpaws found to date. The texture is firm and smooth. The number of fruit per cluster is low, often in singles, which simplifies harvesting. The fruit possesses a color break at picking stage which is a major advantage in harvesting the fruit. The fruit firmness plus the thick skin will help in shipping and handling. This variety is one of three varieties newly identified as having potential to establish a commercial pawpaw industry.

Description

BACKGROUND OF THE INVENTION[0001]The present invention relates to a new and distinct and superior variety of the pawpaw which is of interest for its fruit.[0002]The species—Asimina triloba (L.) Dunal—is the largest native edible fruit of North America, a member of the Annonaceae family, and thus a relative of the cherimoya, sweetsop, guanabana and custard apple (Annona cherimola, A. squamosa, A. muricata and A. reticulata), all of which are popular fruits that are widely cultivated in tropical and subtropical regions of the world, including southern Florida and southern California. The pawpaw is the only truly temperate member of the Annonaceae, being indigenous to a region stretching from the Great Lakes to the Gulf Coastal Plain and from the Chesapeake Bay to the Great Plains.[0003]Currently, the pawpaw is considered to be semi-domesticated. Native Americans casually cultivated the tree, as did the white settlers who displaced them. The selection, propagation and naming of pawpaw ...
