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 […]
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 […]
