Cucurbit Genetics Cooperative Report 8:31-32 (Article 12) 1985 Wehner, Todd C. Department of Horticultural Science, North Carolina State University Raleigh, NC 27695-7609 In the North Carolina State University cucumber breeding program, numerous hybrids, lines and families are evaluated each year in field trials. Most of the data collected is numeric, involving measurement of yield, earliness, […]

1985 Cucumber Reports
Report No. 8 Cucumber (Cucumis sativus) Segregation of the determinate (de) allele in crosses between Cucumis sativus L. and C. sativus var. hardwickii R. (Alef.) D.E. Delaney and R.L. Lower (USA) CGC 8:2-3 (1985) Near-isogenic lines of several cucumber varieties Henry M. Munger (USA) CGC 8:4-6 (1985) Short petiole, a useful seedling marker for genetic studies in cucumber A.P.M. den Nijs and I.W. […]
Effects of the Determinate Locus on Number of Lateral Branches in Crosses between Four Cucumber Lines and Cucumis sativus var. hardwickii L.
Cucurbit Genetics Cooperative Report 7:3-5 (article 1) 1984 D.E. Delaney and R.L. Lower University of Wisconsin, Madison, WI 53706 The shorter vine and concentrated fruit set of determinate pickling cucumbers are well suited to once-over mechanical harvesting (3). However, determinate and short internode dwarf types have fewer and shorter lateral branches than the normal indeterminate […]
Facilitation of Self-pollination in Gynoecious Cucumber with Silver Nitrate Treatment of Cuttings
Cucurbit Genetics Cooperative Report 7:6-7 (article 2) 1984 Soo-Nyeon Kwack and Kunimitsu Fujieda University Farm, Faculty of Agriculture, Kyushu University, Kasuyamachi, Fukuoka, Japan Obtaining self-pollinated seeds from gynoecious cucumber plants selected from segregating populations presents a serious problem for the plant breeder. In this study, we have investigated the application of gibberellic acid (GA) and […]
Pickling Cucumber Inbred Line Development by Full-sib Family Selection II
Cucurbit Genetics Cooperative Report 7:8 (article 3) 1984 K. Lertrat and R. L. Lower University of Wisconsin, Madison, WI 53706 One of the goals of our breeding program is the development of a commercial high-yielding mechanically harvestable hybrid cultivar. After the completion of three cycles of selection for improving fruit number per plant in two […]
Pickling Cucumber Population Improvement for Increased Fruit Yield II
Cucurbit Genetics Cooperative Report 7:9 (article 4) 1984 K. Lertrat and R. L. Lower University of Wisconsin, Madison, WI 53706 Direct selection to improve fruit number per plant has been used as one of the breeding strategies to improve pickling cucumber yield for a once-over mechanical harvesting system in our breeding program. The population improvement […]
Chlorflurenol-induced Seed Coat Development in Parthenocarpic Pickling Cucumbers
Cucurbit Genetics Cooperative Report 7:10-11 (article 5) 1984 A.P.M. den Nijs and G. de Wolf Institute for Horticultural Plant Breeding, P.O. Box 16, 6700 AA Wageningen, The Netherlands Application of chlorflurenol to pickling cucumbers to accelerate and concentrate yield for once-over mechanical harvest by inducing parthenocarpic fruit set has met with difficulties related to unpredictable […]
Improving the Fertility of Tetraploid Cucumbers
Cucurbit Genetics Cooperative Report 7:12-13 (article 6) 1984 A.P.M. den Nijs and D.L. Visser Institute for Horticultural Plant Breeding (IVT), P.O.B. 16, 6700 AA Wageningen, The Netherlands In our breeding program to introduce resistance genes from wild Cucumis species into C. sativus, we have attempted to overcome crossing barriers by using tetraploid cucumbers as the […]
Effect of Length of Vegetative Phase on Total Dry Matter Production and Its Partitioning
Cucurbit Genetics Cooperative Report 7:14-16 (article 7) 1984 D.R. Ramirez and T.C. Wehner Department of Horticultural Science, North Carolina State University, Raleigh, NC 27695-7609 The onset of fruit development usually determines the extent of vegetative growth in crops. The length of both vegetative and reproductive phases in the growth of plants have been claimed to […]
Growth Analysis of Three Cucumber Lines Differing in Plant Habit and Yield
Cucurbit Genetics Cooperative Report 7:17-18 (article 8) 1984 D.R. Ramirez and T.C. Wehner Department of Horticultural Science, North Carolina State University, Raleigh, NC 27695-7609 It is known that the activity of a developing fruit in a cucumber plant inhibits the development of fruit that set later (1), as well as the development of other plant […]
