Narrative
Plant and pod characteristics of 'KnuckleHull-VNR' are quite similar to those of 'Knuckle Purple Hull'. 'KnuckleHull-VNR' has a high bushy growth habit and produces dry pods at Charleston, S.C., in 68 to 74 days. Pod set is concentrated, and pods are borne above foliage level in a scattered fashion. Dry pods are attached to the peduncles in a pendant fashion. Each peduncle typically produces two pods. A typical 'KnuckleHull-VNR' pod is slightly curved, 20 cm long, and contains 14 peas. Pod color is light green (with purple pigmentation at both ends) when immature, purple (glossy) at optimum green-shell maturity, and dark purple (non-glossy) when dry. Fresh peas have a semi-crowder to crowder shape and a light green color. Dry 'KnuckleHull-VNR' peas have a brown-colored, smooth seed coat, and are smaller than 'Knuckle Purple Hull'(weight per 100 dry peas: 'KnuckleHull-VNR', 15.2 g; and 'Knuckle Purple Hull', 19.7 g). 'KnuckleHull-VNR is highly resistant to Blackeye cowpea mosaic virus. It is also homozygous for the Rk gene that conditions resistance to southern root-knot nematode [M. incognita (Kofoid and White) Chitwood], Javanese root-knot nematode [M. javanica (Treub.) Chitwood], and northern root-knot nematode [M. hapla Chitwood].

Pedigree
Date released:
18 Oct 2002
Description:
Efforts to develop 'KnuckleHull-VNR' were initiated with the evaluation of a collection of 61 knuckle purple hull-type breeding lines. Exact pedigrees are unknown, but each line was believed to be the result of a cross between the root-knot nematode-resistant US-427 and a Blackeye cowpea mosaic virus-resistant breeding line. The 61 lines were evaluated in a 1997 field planting and subjected to a selection effort to develop homozygous, knuckle purple hull-type populations. Progenies of single plants selected from the 1997 field planting were grown in a winter 1997/1998 greenhouse planting and an additional cycle of selection was completed. 'KnuckleHull-VNR' originated as the bulk of the progeny of one of the winter 1997/1998 single-plant selections grown in a spring 1998 greenhouse planting
