Cucurbit Genetics Cooperative Report 8:4-6 (Article 2) 1985 Henry M. Munger Cornell University, 410 Bradfield Hall, Ithaca, NY 14853 In over 40 years of cucumber breeding at Cornell, a number of near-isogenic lines have been bred by the backcross method. A few have been released as varieties and the rest as germplasm, but not all […]

Short Petiole, A Useful Seedling Marker for Genetic Studies in Cucumber
Cucurbit Genetics Cooperative Report 8:7-8 (Article 3) 1985 A.P.M. den Nijs and I.W. Boukema Institute for Horticultural Plant Breeding (IVT), P.O. Box 16, 6700 AA Wageningen, The Netherlands During a visit of the first author to the Ukrainian Research Institute of Vegetable Gardening in Charkov, USSR, Dr. M.C. Efimov demonstrated the use of the ‘short […]
Optimum Heat Unit Summation Technique for Harvest Prediction of Fresh-Market and Pickling Cucumbers in North Carolina
Cucurbit Genetics Cooperative Report 8:9-11 (Article 4) 1985 Perry, Katharine B. and Todd C. Wehner Department of Horticultural Science, North Carolina State University Raleigh, NC 27695-7609 Heat unit summation techniques have found widespread applicability for predicting stages of development for many horticultural and agronomic crops (3). Boswell (2) first documented the concept of heat summations […]
Sources of Resistance to Viruses in Two Accessions of Cucumis sativus
Cucurbit Genetics Cooperative Report 8:9-12 (Article 5) 1985 Provvidenti, R. Department of Plant Pathology, New York State Agricultural Experiment Station, Cornell University, Geneva, NY 14456 Recently we have determined that two accessions of Cucumis sativus ‘Surinam’ and ‘TMG-1’ are valuable sources of resistance to the most common viruses affecting this species in the United States. […]
A Giemsa C-banding Procedure for Cucumis Chromosomes
Cucurbit Genetics Cooperative Report 8:13-14 (Article 6) 1985 Ramachandran, C. Agricultural University, Wageningen, 6708 PM, The Netherlands The gene lists of different Cucumis species have been already compiled (3). However, the genes have not been assigned to any of the chromosomes, which are not distinguishable by normal staining procedures. Modern staining techniques like Giemsa C-banding […]
Morphological and Anatomical Comparisons between Two Cucumis sativus, Botanical Varieties: hardwickii and sativus.
Cucurbit Genetics Cooperative Report 8:15-18 (Article 7) 1985 Schuman, D. A., J. E. Staub and B. E. Struckmeyer U.S. Department of Agriculture, Agricultural Research Service and Department of Horticulture, University of Wisconsin, Madison, WI 53706 Cucumis sativus var. hardwickii (R.) Alef. (C. h.) can produce 50 to 76 mature fruits per plant, and thus has […]
Preliminary Yield Evaluation of Inbred Lines Derived from Cucumis sativus var. hardwickii (Royle) Kitamura
Cucurbit Genetics Cooperative Report 8:18-21 (Article 8) 1985 Staub, Jack U. S. Department of Agriculture, Agricultural Research Service and Department of Horticulture, University of Wisconsin, Madison, WI 53706 Recently, usage of Cucumis sativus var. hardwickii (Royle) Kitamura germplasm (hereafter referred to as hardwickii), has increased in cucumber improvement programs because of its potential for increasing […]
Electrophoretic Variation Among Wild Species in the Genus Cucumis.
Cucurbit Genetics Cooperative Report 8:22-25 (Article 9) 1985 Staub, J. and L. Frederick U. S. Department of Agriculture, Agricultural Research Service and Department of Horticulture, University of Wisconsin, Madison, WI 53706 Previously (9), we have documented the relative activity of 47 metabolic enzymes, and general protein in cucumber (Cucumis sativus L.). In conjunction with this […]
Estimates of genetic variances and covariances of three fresh-market cucumber populations.
Cucurbit Genetics Cooperative Report 8:26-28 (Article 10) 1985 Strefeler, Mark S. and Todd C. Wehner Department of Horticultural Science, North Carolina State University Raleigh, NC 27695-7609 An effective plant breeding program depends on the existence of genetic variability, and the estimation of genetic variance and gene effects are vital in formulating the most effective breeding […]
Effects of Location and Grade Size on the Length/Diameter Ratio of Pickling Cucumbers
Cucurbit Genetics Cooperative Report 8:29-30 (Article 11) 1985 Tolla, G. E. Campbell Institute for Research and Technology, Napoleon, OH 43545 The length/diameter ratio (L/D) of pickling cucumber fruit is important to the cucumber processing industry. For small grade size fruit (less than 27 mm dia), which are packed whole by the processing industry, a L/D […]
