Inheritance of Internal Fruit Color in an Interspecific Cross

Cucurbit Genetics Cooperative Report 10:90 (article 48) 1987 R. W. Robinson and J. W. Shail Horticultural Sciences Department, New York State Agricultural Experiment Station, Geneva, New York Cucurbita ecuadorensis, which has white flesh color, was crossed with C. maxima cv. Buttercup, which has deep orange flesh due primarily to [beta]- carotene. Fruit of the interspecific […]

Genetic Variability for Compatibility of an Interspecific Cross

Cucurbit Genetics Cooperative Report 10:88-89 (article 47) 1987 R. W. Robinson and J. W. Shail Horticultural Sciences Department, New York State Agricultural Experiment Station, Geneva, NY 14456 The cross Cucurbita pepo x C. ecuadorensis, which is of interest for breeding squash for multiple disease resistance, was first made by Washek (2). The cross is usually […]

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 […]

A Cucumber Mutant with Increased Hypocotyl and Internode Length

Cucurbit Genetics Cooperative Report 4:19-20 (article 9) 1981 R. W. Robinson and J. W. Shail New York State Agricultural Experiment Station, Geneva, NY 14456 A cucumber plant with a three-fold increase in hypocotyl length was found in the F2 generation after treatment of seed of ‘Lemon’ with thermal neutron radiation. Discrete segregation occurred in the […]

Comparative Electrophoresis of Isozymes of Cucumis Species

Cucurbit Genetics Cooperative Report 1:39 (article 36) 1978 J. T. Puchalski, R. W. Robinson, and J. W. Shail New York Agricultural Experiment Station, Geneva, NY 14456 Electrophoretic patterns of esterase, peroxidase, and leucine aminopeptidase of 24 different Cucumis species were compared. Large differences between several species were found for all these enzyme systems, but some other species […]

Gynoecious Sex Expression in Cucurbita Resulting from an Interspecific Cross

Cucurbit Genetics Cooperative Report 1:31-32 (article 29) 1978 R. W. Robinson, M. A. Boettger, and J. W. Shail New York Agricultural Experiment Station, Geneva, NY 14456 The ‘Buttercup’ and ‘Golden Delicious’ cultivars of Cucurbita maxima were crossed with the ‘Butternut’ and ‘Waltham Butternut’ cultivars of C. moschata. Each parent was monoecious, producing many more staminate than pistillate flowers. Each […]

Genetic Variation of Esterases and Peroxidases in an Interspecific Cucurbita Cross

Cucurbit Genetics Cooperative Report 1:29 (article 27) 1978 J. T. Puchalski, R. W. Robinson, and J. W. Shail New York Agricultural Experiment Station, Geneva, NY 14456 The aim of this preliminary study was to investigate the inheritance and linkage relations of multiple electrophoretic forms of esterases and peroxidases in an interspecific cross between Cucurbita moschata cv. ‘Butternut’ and C.
