Seed development and seed anatomy are very similar (Mohana Rao, 1982). A potential impediment to hybridization is a difference in chromosome number: for Asimina 2n = 18 whereas for Annona 2n = 14 (Darlington and Wylie, 1955). Zimmerman (1941) attempted, but failed, to hybridize A. triloba with Annona squamosa L. and A. x atemoya."

            "text": "The germplasm has been collected to allow the rapid development of high quality pawpaw cultivars. This, together with recent market developments, should support pawpaw cultivation. In 1989, a Michigan marketing cooperative sold wild-harvested pawpaws to a few select restaurants, and a major West Coast distributor of specialty produce received pawpaws for their evaluation. The Burpee Company now offers container-grown pawpaws, and is promoting them with attractive photos and accurate information. In the next 10 years, the general public will probably form their opinion of pawpaws. If they like what they see and taste, the pawpaw's market niche will be secure. If they are turned off by mediocre wild pawpaws of inferior flavor, seediness and looks, then pawpaw breeders will face an uphill battle to win the public confidence."

            "text": "The opportunities for applied research related to the pawpaw will be many. Because of the pulp's unusual properties (highly viscous and hydrophilic, very potent in fruity volatiles, and free of browning reaction on exposure to air), food technologists may want to investigate its potential as a thickener, a flavoring agent, and a cosmetics base. Pharmacologists and chemists may seek to identify economical methods of extracting the pharmacological and insecticidal compounds in the seeds, and of detoxifying the otherwise highly nutritious seed meal. Botanists, entomologists, and plant physiologists may wish to describe the pollinators and the pollination biology of the flowers, and the postharvest physiology of the fruit. With proper plant breeding and scientific research, superior pawpaw cultivars will be developed, markets will be expanded, and pawpaws may become a popular new fruit that is cultivated in temperate regions around the globe."
