Cucurbit Genetics Cooperative Report 5:6-7 (article 3) 1982 M. D. Edwards and R. L. Lower University of Wisconsin, Madison, WI 53706 The compact plant type of cucumbers has been suggested as an alternative to the standard vining phenotype for use in high density plantings (3). Although the plant architecture appears adapted for efficient utilization of […]

Variability for Seed Quality Among Fruit from Individual Compact Cucumber Plants
Cucurbit Genetics Cooperative Report 4:4-5 (article 2) 1981 M.D. Edwards and R. L. Lower University of Wisconsin, Madison, WI 53706 Considerable variability has been observed for emergence percentage and other seed characteristics within a heterogeneous population of compact cucumber genotypes, as reported in a previous study (CGC #4, pp. 2-4). The present study was designed […]
Investigations into the Characteristics of Seeds From Compact Cucumber Plants
Cucurbit Genetics Cooperative Report 4:2-4 (article 1) 1981 M.D. Edwards and R. L. Lower University of Wisconsin, Madison, WI 53706 Seeds from compact (cp cp) cucumber plants often germinate poorly when compared to those from normal vining-type (Cp Cp) plants, particularly in adverse environments.”Compact” seeds also appear somewhat unlike “vining” cucumber seeds. The average seed […]
The Effects of Fermentation and Storage Time on Germination of Cucumber Seeds at Optimal and Suboptimal Temperatures
Cucurbit Genetics Cooperative Report 4:13-16 (article 7) 1981 James Nienhuis and R. L. Lower University of Wisconsin, Madison, WI 53706 One technique commonly used to clean cucumber seeds is to scrape the placental tissue and seed from the seed cavity and allow natural fermentation to occur for a given length of time. At temperatures between […]
An Estimate of the Heritability of Low Temperature Seed Germination in Cucumber
Cucurbit Genetics Cooperative Report 4:12-13 (article 6) 1981 James Nienhuis and R. L. Lower University of Wisconsin, Madison, WI 53706 Reduced germination in low temperature spring soils often results in erratic stands and reduced yield potential in many agronomic and horticultural crops. For this reason, numerous breeding programs and genetic studies have been initiated with […]
The Effect of Fruit Size on Various Fruit Quality Characteristics
Cucurbit Genetics Cooperative Report 3:15-16 (article 9) 1980 J. Mather and R. L. Lower University of Wisconsin, Madison, WI 53706 Fruit firmness is an important factor in assessing the quality of pickling cucumbers. The most frequent measurement of fruit firmness is pounds of pressure as determined by a Magness Taylor Fruit firmness is pounds of […]
Heterosis Estimates for Several Characteristics in a Cross Between a Gynoecious Inbred of Cucumis Sativus L. and C. hardwickii R.
Cucurbit Genetics Cooperative Report 3:20-21 (article 11) 1980 James Nienhuis and R. L. Lower University of Wisconsin, Madison, WI 53706; R. R. Horton, North Carolina State University, Raleigh, NC 27650 Characteristics such as multiple laterals and prolific fruiting make Cucumis hardwickii a potentially useful source of germplasm in a breeding program to improve yield of pickling cucumbers […]
Influence of Reciprocal Donor Scions on Fruit Setting Characteristics of Recipient Scions of Cucumis sativus and C. hardwickii R.
Cucurbit Genetics Cooperative Report 3:17-19 (article 10) 1980 James Nienhuis and R. L. Lower University of Wisconsin, Madison, WI 53706 Cucumis sativus cultivars average approximately 1 1/4 marketable fruit per plant in once-over mechanically harvested operations (5). Low fruit number per plant is presumably due to the inhibitory effect of the seed development of the first […]
An Estimate of Heritability of Fruit Number from a Cross Between a Pickling Cucumber Inbred (Cucumis sativus L.) and an Inbred of C. hardwickii R.
Cucurbit Genetics Cooperative Report 3:10-11 (article 6) 1980 R.R. Horton Department of Horticulture, North Carolina State University, Raleigh, NC 27650 R.L. Lower and J. Nienhuis University of Wisconsin, Madison, WI 53706 Low fruit number per plant is the major factor in reducing yield of once-over mechanically harvested pickling cucumbers (4). Smith et al. (6) used a […]
Screening Cucumbers for Resistance to the Vegetable Leafminer
Cucurbit Genetics Cooperative Report 3:5-6 (article 3) 1980 Gwendolyn Eason, G.C. Kennedy, and R.L. Lower North Carolina State University, Raleigh, NC 27650, University of Wisconsin, Madison, WI 53706 Effective chemical control of the pickleworm and cucumber beetle has reduced natural populations of wasp species which formerly kept the vegetable leafminer, Liriomyza sativae Blanchard, under biological control (2,3,4). Host […]
