Horton, Jr. Department of Horticultural Science, North Carolina State University, Raleigh, NC 27695-7609 In a plant breeding program, it is useful to know the number of seeds per fruit to expect when plants are harvested at mature fruit stage. As a […]

Cluster Analysis of Environments for the U.S.A. Southern Cooperative Slicing Cucumber Trials
Cucurbit Genetics Cooperative Report 11:13-14 (article 6) 1988 Todd C. Wehner Department of Horticultural Science, North Carolina State University, Raleigh, NC 27695-7609 Plant breeders interested in developing slicing cucumbers for the southern U.S.A. often use the southern cooperative trials that cover many locations and seasons in that region. Trials use locations from Virginia (northeast corner […]
Survey of Cucumber Breeding Methods in the U.S.A.
Cucurbit Genetics Cooperative Report 11:9-12 (article 5) 1988 Todd C. Wehner Department of Horticultural Science, North Carolina State University, Raleigh, NC 27695-7609 In 1987, I surveyed public (state university and U.S. Dept. Agric.) and private (seed or processing companies) plant breeders assigned to the improvement of cucumber. The survey included questions on breeding objectives, selection […]
A Revision on Controlled Pollination of Cucumber
Cucurbit Genetics Cooperative Report 11:8 (article 4) 1988 Henry M. Munger Emerson Hall, Cornell University, Ithica, NY 14853 Lower and Edwards (1) in discussing pollination technique for cucumber state that “pistillate flowers are receptive in the morning or up to mid-day on the day they open”. This is exactly the statement I made for many […]
In Vitro Regeneration and Flowering of Cucumber Cultivars and Lines Cultured from Excised Seed
Cucurbit Genetics Cooperative Report 11:5-7 (article 3) 1988 W. Msikita, R.M. Skirvin, J.A. Juvik and W.E. Splittstoesser Department of Horticultural, University of Illinois, Urbana, IL 61801. The ability to obtain whole plants from a single seed may be important when there is a limited number of seeds. Recently, Cade et al. (1) reported shoot regeneration […]
Embryogenesis from Cotyledon-Derived Callus of Cucumis sativus L.
Cucurbit Genetics Cooperative Report 11:3-4 (article 2) 1988 Rebecca M. Cade, Todd C. Wehner, and Frank A. Blazich Department of Horticultural Science, North Carolina State University, Raleigh, NC 27695-7609. Early research on tissue culture of cucurbits dealt with the formation of somatic embryos in culture (2, 4). However, only recently have plants been regenerated through […]
Development of Callus and Somatic Embryos from Zygotic Embryos of Cucumber (Cucumis sativus L.)
Cucurbit Genetics Cooperative Report 11:1-2 (article 1) 1988 J.B.M. Custers, J.E.M. van Deelen and J.H.W. Bergervoet Institute for Horticultural Plant Breeding (OVT), P.O. Box 16, 6700 AA Wageningen, The Netherlands In the cross Cucumis sativus x C, melo seeded fruits often develop, but the embryos cease growth at the globular-0shaped stage (2). Embryo rescue procedures, […]

Further linkage studies in Cucumis sativus L.
Cucurbit Genetics Cooperative Report 10:39-40 (article 23) 1987 S. Zijlstra Institute for Horticultural Plant Breeding (IVT), P.O. Box 16, 6700 AA Wageningen, The Netherlands In 1986 linkage studies for seven combinations of two different marker genes have been continued at the IVT. Involved were the recessive marker genes bi (bitterfree), cp (compact), ccu (susceptibility to […]
Pollen Mother Cell Meiosis in the Haploid of Cucumis ficifolius A. Rich
Cucurbit Genetics Cooperative Report 10:37-38 (article 22) 1987 L. Zagorcheva, M. Alexandrova and C. Kichukova Maritsa Vegetable Crops Research Institute, Plovdiv, Bulgaria Haploid forms in the genus Cucumis ficifolius have not been reported previously in the literature. Tetraploid (2n=48) (1,2) and hexaploid (2n=72) forms (1) have been established. With C. ficifolius (2n=24) autonomous apomictic propagation […]
