January 9, 2006. Technical Abstract: The USDA has developed a new Habanero-type pepper cultivar named ‘TigerPaw-NR’. The new cultivar is the product of a conventional recurrent backcross breeding procedure to transfer a dominant root-knot nematode resistance gene from the Scotch Bonnet accession PA-426 into the Habanero-type accession PA-350. ‘TigerPaw-NR’ was derived from a single F3BC4 plant grown in 2002. ‘TigerPaw-NR’ is homozygous for a dominant gene conditioning a high level of resistance to the southern root-knot nematode, the peanut root-knot nematode, and the tropical root-knot nematode. ‘TigerPaw-NR’ has a compact plant habit and produces attractive,lantern-shaped, orange-colored fruit. The results of three replicated field studies conducted at Charleston, S.C., indicate that the fruit and yield characteristics of ‘TigerPaw-NR’ are comparable to those of currently available Habanero-type cultivars. A typical fruit weighs 7.8 g, is 2.7 cm wide x 4.4 cm long, and is extremely pungent (348,634 Scoville heat units). Root-knot nematodes are major pests of peppers in the United States, and all Habanero-type cultivars currently available to commercial growers and home gardeners are susceptible. The root-knot nematode resistant ‘TigerPaw-NR’ is recommended for use by both commercial growers and home gardeners.
