Abstract

Diseases, particularly gummy stem blight [Didymella bryoniae (Auersw.) Rehm], downy mildew [Pseudoperonospora cubensis (Berk, and Curt.) Rostow], and powdery mildew [Sphaerotheca fuliginea (Schlecht) Poll], are major factors limiting production of muskmelon in the southern United States (Anonymous, 1962; Chiu, 1948; Ellis, 1951; Norton and Prasad, 1965; Prasad and Norton, 1967; Winstead et al., 1960). Severe economic losses have been reported in the field, in transit, and in storage. Although satisfactory control of gummy stem blight (GSB), downy mildew (DM), and powdery mildew (PM) 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, only three cultivars—Chilton, Gulfcoast, and AU-rora-are reported to be resistant to GSB (Norton, 1971; Norton, 1972; Norton et al., 1985). The discovery that plant introduction 140471 had a high level of resistance to GSB (Sowell et al., 1966) led to the initiation of an Alabama Agricultural Experiment Station muskmelon breeding program to develop multiple disease-resistant breeding lines with high yields of excellent-quality fruit (Norton and Prasad, 1965; Prasad and Norton, 1967).

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).
