Abstract
‘Kiawah’ (kee'-a-waw) southernpea [Vigna unguiculata] (L.) Walp.] has been released by ARS/USDA as a replacement for ‘Pinkeye Purple Hull,’ a widely grown commercial cultivar. ‘Kiawah’ is well adapted for production throughout the southeastern United States where it can be expected to produce excellent yields of high quality, pinkeye-type peas. The major attribute of ‘Kiawah’ is its high level of resistance of root knot, a major root disease of southernpea incited by several species of the root-knot nematode genus Meloidogyne. The new cultivar is named in honor of the friendly Kiawah Indian Tribe, which welcomed and helped the original English settlers of Charleston, S.C.
Abstract
The Arkansas Agricultural Experiment Station announces the release of ‘Encore’ southernpea [Vigna unguiculata (L.) Walp], ‘Encore’ has potential as both a commercial and home garden cultivar because of its high yield (Table 1), concentrated set, and bush plant habit (Fig. 1).
Abstract
A major limiting factor in the production of southernpeas (Vigna unguiculata (L.) Walp) is the relative susceptibility of most cultivars to one or more virus diseases. ‘Worthmore’, a new southernpea cultivar of the purple hull crowder type, was selected for its resistance or tolerance to several virus diseases. ‘Worthmore’ appears well suited for home gardens, fresh market, and processing.
Abstract
‘Royal Blackeye’ southernpea [Vigna unguiculata (L.) Walp.] was released in 1985 by the Louisiana Agricultural Experiment Station. This southernpea was developed primarily for local fresh market use. The purple hulls and blackeye seed coat pattern combination is unique among released cultivars.
Abstract
‘Carolina Cream’ is a new southernpea [Vigna unguiculata (L.) Walp.] cultivar that was approved for release in July 1982 by the Agricultural Research Service of the USDA. It is well-adapted for production throughout the southeastern United States, where it can be expected to produce excellent yields of high quality, cream-type peas. Major attributes of the new cultivar are its excellent culinary quality and its resistances to the cowpea curculio (Chalcodermus aeneus Boehman), the major insect pest of the southernpea, and Cercospora leaf spot [Cercospora cruenta Sacc. (= Mycosphaerella cruenta Latham)], a major foliage disease of the crop. Cercospora leaf spot on southernpea also can be incited by Cercospora canescens Ell. & Martin.
Abstract
The average frequency of observable outcrossing among 6 genotypes of southernpea (Vigna unguiculata (L.) Walp.) in a population of 9,987 plants was 0.59% and varied from 1.42% in AU 70.4 to 0% in Ala. 963.8G1-4. Outcrossing as high as 4.26% was recorded in a single plot of ‘Giant Blackeye’.
Abstract
‘Freezegreen’ southernpea, (Vigna unguiculata (L.) Walp.) has been released by the Auburn University Agricultural Experiment Station to fill a need in the processing industry for a cultivar which maintains its green seed color to maturity. ‘Freezegreen’ should have added consumer appeal because of a more uniformly green frozen pack and an enhanced green color.
Abstract
‘Colossus 80’ southernpea [Vigna unguiculata (L.) Walp] has been released by the U.S. Department of Agriculture and Clemson University as a replacement for ‘Colossus’, a widely adapted and popular home garden and fresh-market cultivar that was released by Clemson University in 1972 (8). ‘Colossus 80’ is highly resistant to Cercospora leaf spot (CLS), a disease incited by Cercospora cruenta Sacc. (= Mycosphaerella cruenta Latham) 5 . CLS is one of the most serious foliage diseases of southernpeas in the southeastern United States and infection of susceptible cultivars results in premature defoliation and reduced yields. The original ‘Colossus’ is highly susceptible to this disease. Fery et al. (7) reported reductions of 36, 25, 10, and 3% in total seed yield, pod number, seed number per pod, and average weight per 100 seed, respectively, in a naturally infected ‘Colossus’ planting.
