Genetic Analysis of Isozyme Variants in Cucurbita pepo
Cucurbit Genetics Cooperative Report 9:104-106 (article 34) 1986 Weeden, N.F., R.W. Robinson and J.W. Shail Dept. of Horticultural Sciences, New York Agricultural Experiment Station, Geneva, NU 14456 Considerable isozyme polymorphism has been identified in cultivars of Cucurbita pepo (1,2,3,4), and a correlation between the particular activity bands and fruit types was noted by Ignart and […]
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 […]
Isozyme Studies Indicate that the Genus Cucurbita is an Ancient Tetraploid
Cucurbit Genetics Cooperative Report 7:84-85 (article 37) 1984 Weeden, N.F. New York State Agricultural Experiment Station, Cornell University, Geneva, NY 14456 The high chromosome number (2n=40) of Cucurbita suggests that this genus may be of polyploid origin. Evidence for allotetraploidy in several Cucurbita species was provided in cytogenetic studies of Weiling (3). However, remarkably few […]
Linkage between an Isozyme Locus and One of the Genes Controlling Resistance to Watermelon Mosaic Virus 2 in Cucurbita ecuadorensis
Cucurbit Genetics Cooperative Report 7:86-87 (article 38) 1984 Weeden, N.F., R.W. Robinson and F.Ignart* Dept. Horticultural Sciences, New York Agricultural Experiment Station, Geneva NY 14456 Resistance to watermelon mosaic virus 2 (WMV-2) has been found in Cucurbita ecuadorensis (2). The resistant phenotype appears to be controlled by more than one locus (1), but little is […]
A Nuclear Gene Codes for the Plastid-specific Aldolase in Cucurbita Species
Cucurbit Genetics Cooperative Report 7:88 (article 39) 1984 Weeden, N.F. Dept. Horticultural Sciences, New York State Agricultural Experiment Station, Geneva, NY 14456 At least two forms of fructose 1,6-diphosphate aldolase (EC 4.1.2.13) are present in leaves of Cucurbita species. One of these isozymes is localized in the plastid compartment while the other is cytosolic (1). […]
