Interpretive Summary: PA-593 is a new sweet cherry-type pepper line that has been selectively bred by USDA ARS scientists to be resistant to the most common species of root-knot nematode that cause damage to pepper in the southern United States. In addition to being resistant to root-knot nematodes, PA-593 produces fruit that are very similar in color, shape, and size to other sweet cherry-type pepper cultivars that are grown commercially. During field trials in Charleston, South Carolina, PA-593 also produced yields similar to its commercially grown parent cultivar Sweet Cherry. This new pepper line will allow pepper breeders to incorporate nematode resistance into their new pepper cultivars while maintaining the desired commercial traits associated with sweet cherry-type peppers.

Technical Abstract: PA-593 is a new sweet cherry-type pepper line containing the ‘N’ gene, providing resistance to the most prevalent root-knot nematodes (RKN) in the Southern United States. PA-593 has shown comparable growth, fruit, and yield characteristics to commercially available cultivars of sweet-cherry type peppers. PA-593 will provide breeders with a useful resource for incorporating RKN resistance into their breeding programs to produce commercial sweet cherry-type pepper varieties. This root-knot nematode resistant pepper line was developed by the Agricultural Research Service, U.S. Department of Agriculture.
