Cucurbit Genetics Cooperative Report 10:11 (article 11) 1987 R. W. Robinson Department of Horticultural Sciences, New York State Agricultural Experiment Station, Geneva, NY 14456 PI 197087, a cucumber introduction from India, is notable for its multiple disease resistance. It has been reported (1,2,4) to be resistant to seven diseases and red spider mites. It is […]
Cucumber Reports
Independence of gl and yc
Cucurbit Genetics Cooperative Report 10:11 (article 10) 1987 R. W. Robinson Horticultural Sciences Department, New York State Agricultural Experiment Station, Geneva, NY 14456 Glabrous (gl) and yellow cotyledon (yc) cucumber mutants were orginally considered, on the basis of no double recessives being found in a repulsion phase F2 to be linked on the same chromosome […]
Inheritance of Opposite Leaf Arrangement in Cucumis sativus L.
Cucurbit Genetics Cooperative Report 10:10-11 (article 9) 1987 R. W. Robinson Horticultural Sciences Department, New York State Agricultural Experiment Station, Geneva, NY 14456 Cucumber plants normally have alternate leaves, with a single leaf per node at 180° angle from leaves at adjacent nodes. The Lemon cultivar is heterogeneous for leaf arrangement, with some plants having […]
Genetic Variation in Soluble Solids of Cucumber Fruit
Cucurbit Genetics Cooperative Report 10:9 (article 8) 1987 R. W. Robinson Department of Horticultural Sciences, New York State Agricultural Experiment Station, Geneva, NY 14456 High soluble solids of cucumber fruit can be detrimental for pickling, due to bloating (1), but may benefit flavor of slicing cucumbers. Genetic variation exists in cucumber for fruit soluble solids, […]
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 […]
Composition of Nuclear DNA in Cucumis species
Cucurbit Genetics Cooperative Report 10:4-6 (article 3) 1987 C. Ramachandran College of Horticulture, Kerala Agricultural University, Vellanikkara 680651, India R.K.J. Narayan Department of Agricultural Botany, University College of Wales, Aberystwyth, U.K. The genus Cucumis comprises about thirty species of Asian and African origin. The diploid species are dibasic with haploid chromosome numbers, n=7 or n=12. […]
Comparison of Fruit-Set Concentration of Pickling Cucumbers under Greenhouse and Field Conditions
Cucurbit Genetics Cooperative Report 10:2-3 (article 2) 1987 Haim Nerson, Harry S. Paris, Zvi Karchi, Anneke Govers, Menahem Edelstein and Yosef Burger Department of Vegetable Crops, Agricultural Research Organization, Newe Ya’ar Experiment Station, P.O. Haifa, Israel The shortage and expense of hand labor for multiple harvest of pickling cucumbers are major factors gearing this crop […]
