Cucurbit Genetics Cooperative Report 10:35-36 (article 21) 1987 L. Zagorcheva Maritsa Vegetable Crops Research Institute, Plovdiv, Bulgaria The incompatibility barrier of C. ficifolius with C. sativus was studied in 1985 under greenhouse conditions. Treatments included sib- and self- pollination and unpollinated female flowers to check apomictic seed production (Table 1.). The reason for this check […]

Optimum plant density for multiple-harvest yield of determinate and indeterminate cucumbers
Cucurbit Genetics Cooperative Report 10:29-30 (article 18) 1987 Todd C. Wehner and Conrad H. Miller Department of Horticultural Science, North Carolina State University, Raleigh, NC 27695-7609 The determinate plant type is conditioned by a recessive, single-gene mutant (1). It causes the main stem to terminate in flower buds, and is often associated with shorter vine […]
Value of 12 Season-Location Combinations for Cucumber Yield Trials in North Carolina
Cucurbit Genetics Cooperative Report 10:27-28 (article 17) 1987 Todd Wehner Department of Horticultural Science, North Carolina State University, Raleigh, NC 27695-7609 New experimental breeding lines of pickling and fresh-market cucumbers are tested in many North Carolina environments before release as cultivars for use in the state. The early stages of testing are most efficiently done […]
