Cucurbit Genetics Cooperative Report 1:10 (article 7) 1978 R. W. Robinson New York Agricultural Experiment Station, Geneva, NY 14456 It has been proposed that a single recessive gene (m) conditions andromonoecious sex expression, and a different but very closely linked locus governs round versus elongated fruit shape in the cucumber. I have never found a […]

Effects of Silver Nitrate and Gibberellic Acid on Gynoecious Cucumber
Cucurbit Genetics Cooperative Report 1:8-9 (article 6) 1978 R. L. Lower, D. M. Pharr and E. K. Horst North Carolina State University, Raleigh, NC 27650 Research by Beyer (1) and by De Ponti and Kho (2) discuss the effects of silver nitrate alone, and in combination with gibberellic acid, respectively, on sex expression of cucumber. […]
An Interspecific Cross Between Cucumber (Cucumis sativus and Muskmelon (Cucumis melo)
Cucurbit Genetics Cooperative Report 1:6-8 (article 5) 1978 B. J. van der Knaap and A. C. de Ruiter Deruiterzonen B. V., Bleiswijk, The Netherlands In 1971, we started a program for making an interspecific cross between a cucumber and melon. If such a cross would succeed, it would enable us to exchange certain genes between […]
Cucumis hardwickii: A Source of Germplasm for the Cucumber Breeder
Cucurbit Genetics Cooperative Report 1:5 (article 4) 1978 E. K. Horst and R. L. Lower North Carolina State University, Raleigh, NC 27650 Cucumis hardwickii, an annual monoecious cucurbit species resembling C. sativus, hybridizes readily with C. sativus, producing a fertile F1 with no observed reduction of fertility in the F2. C. hardwickii sets larger numbers of fruit per plant […]
Breeding for Fruit Rot Resistance in Cucumber
Cucurbit Genetics Cooperative Report 1:4 (article 3) 1978 J. L. Bowers and M. J. Goode University of Arkansas, Fayetteville, AR 72701 We now have two characters that we think may be helpful in breeding for fruit rot (Rhizoctonia) resistance. A small leaf type was found in our material 3 years ago, and we are in the […]
Fusarium Wilt Resistance of Cucumbers
Cucurbit Genetics Cooperative Report 1:3 (article 2) 1978 G. M. Armstrong and J. K. Armstrong Georgia Experiment Station, Experiment, GA 30212 Fusarium wilt of cucumbers has not been of importance in the United States, but is of considerable importance in other parts of the world. Three different isolates of Fusarium oxysporum f. sp. cucumerinum viz., #ATCC 16416 from Fla., […]
Preliminary Report on in vitro Propagation of Cucumber
Cucurbit Genetics Cooperative Report 1:1-2 (article 1) 1978 W. R. Alsop, W. W. Cure, G. F. Evans, and R. L. Mott North Carolina State University, Raleigh, NC 27650 Preliminary investigations on the feasibility of in vitro propagation of cucumber (Cucumis sativus L.) have been conducted in this laboratory. Shoot regeneration from callus has not been reported for this […]
