The lethal yellow seedling phenotype has been observed in seedlings of the genus Cucurbita. It was first reported in C. pepo (1) and more recently in C. maxima (2). In both cases a single recessive gene was reported to control the trait. It is reported here the occurrence and the inheritance of the lethal yellow […]

Inheritance of Hard Rind in C. maxima x C. moschata Crosses
Cucurbit Genetics Cooperative Report 17:122-124 (article 36) 1994 Koch, P.S. and P.T. Della Vecchia Agroflora S/A, Caixa Postal 427, 12900-000, Braganca Paulista, SP, Brazil Along with the development of cv. Alice (1), a bush type of C. maxima, we have selected a sister line with fruit carrying the hard rind trait. Because hard rind lines […]
Response Reaction of Melon Genotypes Heterozygous for the Prv1 Gene to Mechanical Inoculation of PRSV-W
Cucurbit Genetics Cooperative Report 17:81-82 (article 23) 1994 Vitti, A.J., P.T. Della Vecchia, and R. Wierzbicki Agroflora S/A, Caixa Postal 427, 12900-000, Braganca Paulista, SP, BRAZIL In a previous study on the inheritance of Papaya Ring Spot Virus-Watermelon (PRSV-W) on melon (1) we have observed the appearing of necrotic local lesion on cotyledons of mechanically […]
Inheritance of Short-day response to Flowering in Crosses Between a Cucumis sativus var. hardwickii (R.) Alef. Line and Cucumis sativus L. Lines
Cucurbit Genetics Cooperative Report 5:4-5 (article 2) 1982 P. T. Della Vecchia, C. E. Peterson and J. E. Staub University of Wisconsin, Madison, WI 53706 Cucumis sativus var. hardwickii (R.) Alef. has been suggested as a possible source of germplasm for increasing yield in pickling cucumbers (1). Potentially the most useful characteristic of ‘hardwickii’ types is their ability to […]
Effect of the Duration of Short-day Treatment on the Flowering Response of a Cucumis sativus var. hardwickii (R.) Alef. Line
Cucurbit Genetics Cooperative Report 5:2-3 (article 1) 1982 P. T. Della Vecchia, C. E. Peterson, and J. E. Staub University of Wisconsin, Madison, WI 53706 Since Horst and Lower (1) first reported on the potential of Cucumis sativus var. hardwickii (R.) Alef. as a possible source of germplasm for increasing yield in pickling cucumbers, there has been considerable interest by […]
