The Influence of Temperature on Powdery Mildew Resistance in Cucumber
Cucurbit Genetics Cooperative Report 2:9-10 (article 5) 1979 H. M. Munger Departments of Plant Breeding and Vegetable Crops, Cornell University, Ithaca, NY 14853 In studying the inheritance of powdery mildew resistance in cucumber, we have repeatedly noticed that plants in the greenhouse with any given level of resistance show much more mildew during the winter […]
Linkage of Bacterial Wilt Resistance and Sex Expression Genes in Cucumber
Cucurbit Genetics Cooperative Report 2:8 (article 4) 1979 A. F. Iezzoni and C. E. Peterson Department of Horticulture, University of Wisconsin, Madison, WI 53706 Cucumber lines resistant to bacterial wilt caused by Erwinia tracheiphila were established for each of the four sex types (gynoecious, monoecious, hermaphrodite, and andromonoecious) to investigate a possible linkage between the gene for […]
Development and Release of Breeding Lines of Cucumber with Resistance to the Twospotted Spider Mite, Tetranychus urticae Koch
Cucurbit Genetics Cooperative Report 2:6-7 (article 3) 1979 o. M. B. de Ponti Institute for Horticultural Plant Breeding, Wageningen, The Netherlands Based on a thorough study of the host-parasite relationship using cucumber varieties with different levels of resistance to the twospotted spider mite, two resistance tests were developed: a laboratory test (1) measuring acceptance and […]
Breeding Glabrous Cucumber Varieties to Improve the Biological Control of the Glasshouse Whitefly
Cucurbit Genetics Cooperative Report 2:5 (article 2) 1979 O. M. B. de Ponti Institute for Horticultural Plant Breeding, Wageningen, The Netherlands On glasshouse tomatoes in the Netherlands, the biological control of the glasshouse whitefly (Trialeurodes vaporariorum Westwood) with the parasitic wasp (Encarsia formosa Gahan) is successfully applied on an ever increasing scale. On glasshouse cucumbers, however, despite repeated and […]
The Effects of Illumination, Explant Position, and Explant Polarity on Adventitious Bud Formation In Vitro of Seedling Explants of Cucumis sativus L. cv. ‘Hokus’
Cucurbit Genetics Cooperative Report 2:2-4 (article 1) 1979 J. B. M. Custers and L. C. Buijs Institute for Horticultural Plant Breeding, Wageningen, The Netherlands In certain interspecific crosses in Cucumis, the embryos abort at the early embryonic stages. Artificial culture of very young embryos proved to be unsuccessful in many plants. Surprisingly, research on somatic embryo […]

Screening Cucumbers for Resistance to Pickleworm
Cucurbit Genetics Cooperative Report 1:16 (article 15) 1978 E. V. Wann, J. F. Robinson, R. L. Lower, J. M. Schalk and Terry L. Pulliam US Vegetable Laboratory, USDA, SEA, Charleston, SC 29407 and Department of Horticultural Science, North Carolina State University, Raleigh, NC 27650 We have developed procedures for rearing and artificially infesting cucumber plants […]
Spontaneous Mutation in the Cucumber
Cucurbit Genetics Cooperative Report 1:15 (article 14) 1978 R. W. Robinson New York Agricultural Experiment Station, Geneva, NY 14456 A search was made for spontaneous mutants among 30,030 plants of 13 cucumber cultivars. Several chlorophyll deficient mutants were found, each conditioned by a different single recessive gene. Surprisingly, male sterile mutants occurred in a frequency […]
