Cucurbit Genetics Cooperative Report 10:104 (article 54) 1987 R. W. Robinson Horticultural Sciences Department, New York State Agricultural Experiment Station, Geneva, NY All cultivated cucurbits prefer warm temperature. They are subject to chilling injury and are very sensitive to frost. A very light frost, not sufficiently cold to injure other tender crops such as beans […]

Anther and Ovule Culture of Cucurbita
Cucurbit Genetics Cooperative Report 10:92 (article 50) 1987 J. W. Shail and R. W. Robinson Horticultural Sciences Department, New York State Agricultural Experiment Station, Geneva, NY 14456 Previous attempts to grow plants from cultured anthers have been successful for cucumber (3) and muskmelon (2) but not for squash (1). We found that squash pollen did […]

Moriarty Horticultural Sciences Department, New York State Agricultural Experiment Station, Geneva, NY 14456 PI 287531, an introduction from Naples, Italy of the cultivar Long Neopolitan, was included in the 1980 planting of Cucurbita maxima at the North East Regional […]
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 […]
Downy Mildew Resistance in Cucurbita
Cucurbit Genetics Cooperative Report 10:87 (article 46) 1987 R. W. Robinson Horticultural Sciences Department, New York State Agricultural Experiment Station, Geneva, NY C. A. John ¹ Castle Seed Co., Homestead, Florida 33031 Cucurbita ecuadorensis and C. okeechobeensis are generally considered to be not very closely related. They were placed in different groups, when Cucurbita species […]
Novel Variation in an Interspecific Cross
Cucurbit Genetics Cooperative Report 10:85-86 (article 45) 1987 R. W. Robinson Horticultural Sciences Department, New York State Agricultural Experiment Station, Geneva, NY 14456 An unusually large number of different chlorophyll deficient mutants was observed in breeding lines derived from the interspecific cross, Cucurbita maxima x C. ecuadorensis.

Inheritance of Fruit Skin Color in Cucurbita moschata
Cucurbit Genetics Cooperative Report 10:84 (article 44) 1987 R. W. Robinson Horticultural Sciences Department, New York State Agricultural Experiment Station, Geneva, NY 14456 Mature fruit of C. moschata cv. Long Neopolitan (PI 287531) have mottled dark and lighter green skin, in contrast to the buff color of ‘Butternut’. The F1 of ‘Butternut’ x ‘Long Neopolitan’ […]
