An Improved Method of BA Application for the Promotion for the Promotion of Fruit Set in Muskmelon
Cucurbit Genetics Cooperative Report 6:51 (article 26) 1983 Henry M. Munger and David P. Lane Cornell University, Ithaca, NY 14853 The artificial cytokinin N6-benzyladenine (BA) greatly improves the percentage of fruit set in hand-pollinated muskmelon (1). This effect is probably even more pronounced in situations where emasculation is involved or where pollinations are made by […]
Potential Sources of Sudden Wilt Resistance in Muskmelon
Cucurbit Genetics Cooperative Report 6:49-50 (article 25) 1983 J. D. McCreight U. S. Department of Agriculture, Agricultural Research Service, P. O. Box 5098, Salinas, CA 93915 Sudden wilt (Pythium ultimum and P. aphanidermatum) of muskmelon has been of increasing importance in California and in Arizona. The disease causes rapid wilting and collapse of the vines just prior […]
Linkage of Red Stem and Male Sterile-1 in Muskmelon
Cucurbit Genetics Cooperative Report 6:48 (article 24) 1983 J. D. McCreight U. S. Department of Agriculture, Agricultural Research Service, P. O. Box 5098, Salinas, CA 93915 The seedling marker gene red stem (3) was crossed with male sterile-1 (1) to determine the linkage relationship between these two loci. Three F2 families segregated 559 green, fertile:195 green, male sterile:221 red […]
Independent Assortment of Red Stem and Yellow Green in Muskmelon
Cucurbit Genetics Cooperative Report 6:47 (article 23) 1983 J. D. McCreight U. S. Department of Agriculture, Agricultural Research Service, P. O. Box 5098, Salinas, CA 93915 Five F2 and 15 repulsion phase backcross (BC) families were scored for red stem (2) and yellow green (3) seedling marker genes. Pooled segregation data indicate independent assortment between these two loci (Table […]
A Third Male Sterile Gene in Muskmelon
Cucurbit Genetics Cooperative Report 6:46 (article 22) 1983 J. D. McCreight and G. W. Elmstrom U. S. Department of Agriculture, Agricultural Research Service, P. O. Box 5098, Salinas, CA 93915 (first author) and IFAS, P. O. Box 388, Leesburg, FL 32748 (second author) A third male sterile gene was discovered in PI 321005 (a cross […]
A Long Internode Mutant in Muskmelon
Cucurbit Genetics Cooperative Report 6:45 (article 21) 1983 J. D. McCreight U. S. Department of Agriculture, Agricultural Research Service, P. O. Box 5098, Salinas, CA 93915 Abnormally long veined plants occurred in 7 of 10 F2 sib progenies from the 11th backcross generation of a cross of ‘PMR 45’ with aphid resistant 90234, derived from PI […]
Peat Pellet Inoculation: A Potential Rapid Screening Method for Fusarium Resistance in Cucumis melo L.
Cucurbit Genetics Cooperative Report 6:43-44 (article 20) 1983 Richard N. McArdle and Stephen A. Kendall Department of Horticulture, University of Maryland, College Park, Maryland 20742 Greenhouse tests for Fusarium resistance in muskmelon typically involve inoculation by dipping young melon plants into spore suspensions (2, 3) or growing in infested soil (1). These methods are time-intensive, cumbersome, and […]

Cucurbit Genetics Cooperative Report 6:41-42 (article 19) 1983 A. N. Kishaba, S. Castle, D. Coudriet, and J. D. McCreight U. S. Department of Agriculture, Agricultural Research Service, Boyden Entomology Laboratory, University of California, Riverside, CA 92521 (first, second and third authors) and U. S. Department of Agriculture, Agricultural Research Service, P. O. Box 5098, Salinas, […]
Effect of Unequal Competition from Bordering Rows on Pickling Cucumber Yield Trial Results
Cucurbit Genetics Cooperative Report 6:38-39 (article 18) 1983 Todd C. Wehner and Conrad H. Miller Department of Horticultural Science, North Carolina State University, Raleigh, NC 27650 Plant breeders usually test new experimental lines for several years in replicated, multiple-harvest trials to determine whether the line should be released for production in a particular growing area.
