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 […]
Genotype-Environment Interaction for Cucumber Yield in 23 North Carolina Environments
Cucurbit Genetics Cooperative Report 10:25-26 (article 16) 1987 Todd C. Wehner Department of Horticultural Science, North Carolina State University, Raleigh, NC 27695-7609 Pickling and fresh-market cucumber cultivars are regularly tested for fruit yield to determine their usefulness for growers in particular areas of North Carolina. Plant breeders developing new cultivars for the state need to […]
