Malate Dehydrogenase Variation in African Cucumis species: A Testable Genetic Hypothesis

Cucurbit Genetics Cooperative Report 9:18-23 (article 6) 1986 J.E. Staub USDA, ARS, Department of Horticulture, University of Wisconsin, Madison, WI 53706 Electrophoretic, cucurbitacin and flavonoid variation; chromosome homology; and plant morphology have been studied to determine taxonomic relationships among cross-compatible species of Cucumis (1, 2, 4, 7, 8, 10, 11, 12, 15). These studies have […]

Leaf Area Prediction Model For Field Grown Cucumbers

Cucurbit Genetics Cooperative Report 9:15-17 (article 5) 1986 N.S. Robbins and D.M. Pharr Department of Horticultural Science, North Carolina State University, Raleigh, N.C. 27695-7609 Several recent studies have suggested that fruit yield in cucumber might be limited by photoassimilate supply (1, 2). Changes in potential for photoassimilate production are related to photosynthetic rate per unit […]

Segregation of the Determinate (de) Allele in Crosses Between Cucumis sativus L. and C. sativus var. hardwickii (R.) Alef.

Cucurbit Genetics Cooperative Report 8:2-3 (Article 1) 1985 D.E. Delaney and R.L. Lower University of Wisconsin, Madison, WI 53706 In 1982, we initiated a breeding program for increasing the number of lateral branches on determinate plant types. The objective was to alter the plant architecture of current determinate lines by incorporating the multiple lateral branching […]
