Flesh Calcium Content of Group Inodorus and Group Reticulatus Muskmelon (Cucumis melo L.) Fruits
Cucurbit Genetics Cooperative Report 12:53-54 (article 23) 1989 Timothy J. Ng and Vermal Carr University of Maryland, Department of Horticulture, College Park, MD 20742-5611 Honeydew and casaba (group Inodorus) muskmelons tend to have extended storage lives when compared to netted (group Reticulatus) muskmelons (5). Decline in storage is usually manifested by flesh softening and breakdown, […]
Ethylene Production by Germinating Seeds of Different Sexual Genotypes of Muskmelon (Cucumis melo L.)
Cucurbit Genetics Cooperative Report 12:51-52 (article 22) 1989 L. Alvarez Universidad de Horticultura, Servicio de Investigacion Agraria, Apartado 727, 50080 Zaragosa The use of gynoecious genotypes has been proposed as a method for muskmelon hybrid seed production. The identification of gynoecious plants is necessary for the introduction of this character into agronomically interesting lines; in […]
Low Temperature Germination in Muskmelon is Dominant
Cucurbit Genetics Cooperative Report 12:50-52 (article 21) 1989 Haim Nelson and Jack E. Staub ARO, Newe Ya’ar Experiment Station, Israel, and USDA-ARS, Department of Horticulture, Univ. Wisconsin, Madison, WI 53706 Muskmelon seed (Cucumis melo L.), like most domestic cucurbits, requires 17 to 18°C for germination (threshold temperature). At lower temperatures the membrane transfer from the […]

Search for Sources of Resistance to Yellowing Disease in Cucumis spp.
Cucurbit Genetics Cooperative Report 12:42-43 (article 18) 1989 C. Soria and M.L. Gomez-Guillamon Universidad Politecnica de Valencia, Spain The unpromising results obtained from earlier experiments seeking sources of resistance to muskmelon yellowing disease in a large collection of different muskmelon (Cucumis melo L.) cultivars under conditions of natural infection led to this present search for […]
Transmission of the Causal Agent of Muskmelon Yellowing Disease
Cucurbit Genetics Cooperative Report 12:40-41 (article 17) 1989 C. Soria and M.L. Gomez-Guillamon Estacion Experimental “La Mayora”, Algarrobo-Costa, (Malaga), Spain Since 1982, a yellowing disease has seriously affected muskmelon (Cucumis melo L.) crops cultivated under polythene greenhouses on the southeast coast of Spain. It now seriously affects the profitability of muskmelon growing in this area […]
Resistance to Sphaerotheca fuliginea (Schlecht. ex Fr.) Poll. in Spanish Muskmelon Cultivars
Cucurbit Genetics Cooperative Report 12:39-40 (article 16) 1989 M.S. Gomez-Guillamon and J.A. Tores Estacion Experimental “La Mayora”, Algarrobo-Costa, 29750 Malaga, Spain In 1987 and 1988 several cultivars of Spanish type melons were inoculated with Sphaerotheca fuliginea race 1 to determine possible sources of resistance to this pathogen. The cultivars chosen were those who in previous […]
