The Reliability of a Seedling Test for Resistance to Root-Knot Nematodes in Cucurbits
Cucurbit Genetics Cooperative Report 7:92-93 (article 41) 1984 Boukema, I.W., G.T.M. Reuling and K. Hofman Institute for Horticultural Plant Breeding (IVT), P.O.B. 16, 6700 AA Wageningen, The Netherlands A seedling test is used to screen for resistance to root-knot nematodes (Meloidogyne incognita Chitw.) in cucurbits (1). The level of resistance is measured by determining the […]
Embryo Size in Cucumis sativus x C. melo as Affected by Irradiation of the Pollen and Genotype of the Female Parent
Cucurbit Genetics Cooperative Report 7:94-95 (article 42) 1984 Custers, J.B.M. and J.H.W. Bergervoet Institute for Horticultural Plant Breeding, P.O. Box 16, 6700 AA Wageningen, The Netherlands The cross Cucumis sativus x C. melo so far failed because the embryos cease their development at the globular- shaped stage (2). Embryo culture procedures suitable for non- hybrid […]
Trisomic Identification of Linkage Groups of Cucurbita
Cucurbit Genetics Cooperative Report 7:96 (article 43) 1984 Graham, J.D., N.F. Weeden and R.W. Robinson Department of Horticultural Sciences, New York State Agricultural Experiment Station, Geneva, NY 14456 Bemis (1) synthesized trisomic stocks of Cucurbita, having 40 chromosomes of C. moschata and one from C. palmata. The five different trisomics we obtained from him are […]
Nuclear DNA Variation in Cucumis Species
Cucurbit Genetics Cooperative Report 7:97-99 (article 44) 1984 Ramachandran, C. Department of Agricultural Botany, University College of Wales, Aberystwyth, U.K. The genus Cucumis includes two sets of species with basic chromosome numbers x = 7 and x = 12, respectively.
