Interspecific Hybridization of Cucumis
Cucurbit Genetics Cooperative Report 1:40 (article 37) 1978 R. W. Robinson and E. Kowalewski New York Agricultural Experiment Station, Geneva, NY 14456 Diallel reciprocal cross pollinations were made among cucumber, muskmelon, and l9 wild species of Cucumis. The only species that crossed with the cucumber was C. Hardwickii; and C. trigonus and C. callosus were the only species to cross with […]
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 […]
Interspecific Crosses of Cucumis Species
Cucurbit Genetics Cooperative Report 1:39 (article 35) 1978 J. D. Norton Auburn University Agricultural Experiment Station, Auburn, AL 36830 Interspecific crosses among Cucumis melo, C. metuliferus, and C. anguria have been attempted over a ten year period. In greenhouse experiments one cross of C. melo x C. metuliferus was accomplished. Further attempts to make this cross resulted in an occasional fruit set with normal fruit […]
White Fly Resistance in Cucumis Species
Cucurbit Genetics Cooperative Report 1:38 (article 34) 1978 E. Kowalewski3 and R. W. Robinson New York State Agricultural Experiment Station, Geneva, NY 14456 Cucumis species were evaluated for resistance to natural infestation with white flies in the greenhouse. Scanning electron and stereoscope microscope studies were made to determine if white fly resistance is related to morphology or […]
Dormancy of Cucumis Species
Cucurbit Genetics Cooperative Report 1:36-37 (article 33) 1978 Claude Heit, R. W. Robinson, and W. Mishanec New York Agricultural Experiment Station, Geneva, NY 14456 Dormancy is seldom a serious problem with seed of cucumber and muskmelon. Freshly harvested seed may be dormant, but this can usually be easily overcome by removal of the seed coats […]

Natural and Induced Mutations in C. pepo
Cucurbit Genetics Cooperative Report 1:35 (article 32) 1978 W. N. Whitwood and J. L. Weigle Robson Seed Farms, Hall, NY 14463 Mutations were induced in a cultivar of C. pepo, ‘Early Prolific Straight Neck’, by ethyl-methanesulfonate (EMS). A 0.035 m concentration of EMS was used to treat 2,000 seeds for 24 hours. The seeds were rinsed […]
