Cucurbit Genetics Cooperative Report 7:54 (article 24) 1984 Risser, Georgette and J.C. Rode I.N.R.A., Centre de Recherches Agronomiques d’Avignon, 84140 Montfavet, France Hand pollination of a melon flower with a mixture of pollen from several plants is difficult because melon pollen is sticky and aggregates. Our objective was to find a non-toxic solvent that could […]

Inoculation Conditions to Evaluate Resistance to Alternaria cucumerina (Ellis & Everh.) Elliot in Muskmelon
Cucurbit Genetics Cooperative Report 7:55-57 (article 25) 1984 Thomas, Claude E. U.S. Department of Agriculture, Agricultural Research Service, U.S. Vegetable Laboratory, 2875 Savannah Highway, Charleston, SC 29407 Alternaria cucumerina incites leaf blight of various cucurbits throughout the world (2). This disease is particularly severe on muskmelon (Cucumis melo L.) in the southeastern and Midwestern production […]

Effects of the Determinate Locus on Number of Lateral Branches in Crosses between Four Cucumber Lines and Cucumis sativus var. hardwickii L.
Cucurbit Genetics Cooperative Report 7:3-5 (article 1) 1984 D.E. Delaney and R.L. Lower University of Wisconsin, Madison, WI 53706 The shorter vine and concentrated fruit set of determinate pickling cucumbers are well suited to once-over mechanical harvesting (3). However, determinate and short internode dwarf types have fewer and shorter lateral branches than the normal indeterminate […]
Facilitation of Self-pollination in Gynoecious Cucumber with Silver Nitrate Treatment of Cuttings
Cucurbit Genetics Cooperative Report 7:6-7 (article 2) 1984 Soo-Nyeon Kwack and Kunimitsu Fujieda University Farm, Faculty of Agriculture, Kyushu University, Kasuyamachi, Fukuoka, Japan Obtaining self-pollinated seeds from gynoecious cucumber plants selected from segregating populations presents a serious problem for the plant breeder. In this study, we have investigated the application of gibberellic acid (GA) and […]
Pickling Cucumber Inbred Line Development by Full-sib Family Selection II
Cucurbit Genetics Cooperative Report 7:8 (article 3) 1984 K. Lertrat and R. L. Lower University of Wisconsin, Madison, WI 53706 One of the goals of our breeding program is the development of a commercial high-yielding mechanically harvestable hybrid cultivar.

Pickling Cucumber Population Improvement for Increased Fruit Yield II
Cucurbit Genetics Cooperative Report 7:9 (article 4) 1984 K. Lertrat and R. L. Lower University of Wisconsin, Madison, WI 53706 Direct selection to improve fruit number per plant has been used as one of the breeding strategies to improve pickling cucumber yield for a once-over mechanical harvesting system in our breeding program. The population improvement […]
