Introduction: This study examined fruit production characteristics of different varieties of pawpaw (Asimina triloba) over a period of 8 years. Methods: Plants of 52 varieties of pawpaw (n = 359) were planted at three locations in southwest Ohio from 2001-2006. Fruit were collected and weighed spring 2005-fall 2012. For further analysis, the 52 varieties were divided into two data categories (varieties not belonging to a genetic group and those assigned a genetic group) based on previous research. Differences in average fruit weight (g), yield (g), and harvest length (days) were analyzed among varieties and genetic groups. Pearson’s r was used to identify any correlation between average fruit weight and total number of fruit produced. Results: Significant differences in average fruit weight were found between genetic groups and individual varieties. Differences in yield and fruit onset were also identified between individual varieties. Significant differences in average fruit weight and yield were seen between growing locations. Comparison of average fruit weight and total fruit number resulted in a significant negative correlation. Discussion: Results indicate that some pawpaw varieties, or groups, generate significantly larger fruit. Results also indicate that planting location makes a difference in fruit production, although future research is needed to identify specific growing factors. A weak negative correlation between average fruit weight and total fruit number indicates that large fruit sets can lead to decreased fruit size. In order to improve fruit quality and tree productivity, potential pawpaw growers must consider many preharvest factors. These findings add to the limited body of evidence about pawpaw fruit in general and indicate that variety and growing location can significantly affect the ultimate commercial potential of pawpaw fruit.
