Abstract
PA-566 is a new pimento-type pepper (Capsicum annuum L.) released 30 Apr. 2010 by the Agricultural Research Service of the U.S. Department of Agriculture. PA566 is the product of a backcross breeding program to incorporate the N root-knot nematode resistance gene into a ‘Pimiento L’type genetic background. ‘Pimiento L’ is a root-knot nematode-susceptible, pimentotype cultivar that is widely grown in the southern states where it can produce good yields under high-temperature conditions. The dominant N gene conditions a high level of resistance to the southern root-knot nematode [Meloidogyne incognita (Chitwood) Kofoid and White], the peanut root-knot nematode [M. arenaria (Neal) Chitwood], and the tropical root-knot nematode [M. javanica (Treub) Chitwood]. The release of PA-566 will provide pepper breeders interested in developing both open-pollinated and F1 hybrid pimentotype cultivars access to a near-cultivar quality parental line that is homozygous for the N root-knot nematode resistance gene.
