Cordate, a Leaf Shape Gene with Pleiotropic Effects on Flower Structure and Insect Pollination
Cucurbit Genetics Cooperative Report 10:8 (article 7) 1987 R. W. Robinson Horticultural Sciences Department, New York State Agricultural Experiment Station, Geneva, NY 14456 Very few leaf shape genes are known for the cucumber. A new cucumber mutant with distinctive leaf shape was induced by thermal neutron radiation of seed of the cultivar Lemon. Leaves of […]
Chlorosis Induced in Glabrous Cucumber by High Temperature
Cucurbit Genetics Cooperative Report 10:7 (article 6) 1987 R. W. Robinson Horticultural Sciences Dept., New York State Agricultural Experiment Station, Geneva, NY 14456 Glabrous (gl) cucumber plants are sensitive to heat stress. When grown in the field at Geneva, NY gl plants often grow well early in the season but, as temperatures increase in midsummer, […]
Allelism Test with Glabrous Cucumber Mutants
Cucurbit Genetics Cooperative Report 10:7 (article 5) 1987 R. W. Robinson Horticultural Sciences Department, New York State Agricultural Experiment Station, Geneva, NY 14456 The radiation-induced glabrous mutant, gl, was found by Inggamer and de Ponti (1) to be allelic to a spontaneous mutant with similar phenotype. Two additional glabrous mutants, derived from different M2 families […]
Blunt Leaf Apex, a Cucumber Mutant Induced by a Chemical Mutagen
Cucurbit Genetics Cooperative Report 10:6 (article 4) 1987 R. W. Robinson Horticultural Sciences Department, New York State Agricultural Experiment Station, Geneva, NY 14456 Seed of ‘Wisconsin SMR 18’ was soaked in 1.0% ethyl methane sulfonate for 21 hours. Plants grown from the treated seed were self pollinated, and the next (M2) generation was screened for […]

Cold Tolerance in the Cucurbitaceae
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 […]
