Plum production in the Southeastern United States is limited because cultivars are susceptible to bacterial canker (Pseudomonas syringae), bacterial fruit and leaf spot (Xanthomonas pruni), black knot (Apisporina morbosa) and plum leaf scald (Xylella fastidiosa). Evaluation of four new cultivars developed by the Alabama Agricultural Experiment Station indicated that AU-Rubrum, AU-Rosa and AU -Cherry were resistant to all the diseases listed, and AU-Amber was resistant to all excapt A. morbosa. Disease ratings were made on trees in six experimental plantings in Alabama, in Georgia test plantings and in grower trials.

Abstract

The inheritance of resistance to cowpea chlorotic mottle virus (CCMV) in southern pea, Vigna sinensis (L.) Savi., Plant Introduction 255811, was determined in crosses with the susceptible cvs. Knuckle Purple Hull, Mississippi Silver, and Princess Anne. Segregation of F2 and backcross populations indicated that resistance to CCMV in P.I. 255811 is governed by 1 major recessive gene pair.

Abstract

In the article “AU-Jubilant' and ‘AU–Producer’ Watermelons“ by J.D. Norton, R.D. Cosper, D.A. Smith, and K.S. Rymal (HortScience 21:1460–1461, Dec. 1986), the following corrections should be noted: The legends to Figs. 3 and 4 were reversed. The legend to Fig. 3 should read “Fruit of ‘AUProducer’ watermelon.”; the legend to Fig. 4 should read “Fruit of ‘AU–Jubilant’ watermelon.” In the legend to Fig. 1, the word should be “Pedigree”. In the literature citations, ref. 1 should read J. Amer. Soc. Hort Sci. instead of HortScience, and, in ref. 7, the volume number should read 105 instead of 195.

Abstract

‘AUrora’ is a multiple disease resistant muskmelon (Cucumis melo L.) cultivar developed by the Dept. of Horticulture, Alabama Agricultural Experiment Station, Auburn Univ., adapted to growing conditions in the Southeastern United States. ‘AUrora’ has resistance to downy mildew (Pseudoperonospora cubensis), powdery mildew, (Spherotheca fuliginea), and gummy stem blight (Didymella bryoniae). ‘AUrora’ is especially suited for home, local and commercial markets where “jumbo” size fruit is preferred.

Abstract

Prevalence of diseases, particularly anthracnose, fusarium wilt, and gummy stem blight, is a major factor limiting production of watermelons in the southern United States. Although satisfactory control of anthracnose and gummy stem blight may be accomplished with the proper application of organic fungicides during normal weather conditions, chemical control is not effective during periods of high humidity and rainfall. Furthermore, the 3 leading cultivars, Charleston Gray, Jubilee, and Crimson Sweet, are not resistant to either anthracnose or gummy stem blight (1,2, 7).
