Notes on Squash Breeding
Cucurbit Genetics Cooperative Report 10:93-99 (article 51) 1987 O. Shifriss 21 Walter Ave., Highland Park, NJ 08904 Interspecific hybridization (11). The cross C. pepo x C. moschata is important from both theoretical and practical points of view. The natural reproductive isolation between these species is not as strong as that between other species of Cucurbita. […]
Relationship between the B Genes of two Cucurbita Species
Cucurbit Genetics Cooperative Report 9:97-99 (article 31) 1986 Shifriss, O. Department of Horticulture and Forestry, Rutgers-The State University,New Brunswick, NJ 08903 Gene B conditions precocious depletion of chlorophyll in fruits of Cucurbita pepo L. And chlorophyll depletion is followed by precocious yellow pigmentation. In addition, B. can affect leaf blades depending upon the genetic background […]
Independence of Genes Ses-B and M in Cucurbita pepo L.
Cucurbit Genetics Cooperative Report 7:64-65 (article 28) 1984 Bloksberg, L.N. and O. Shifriss Department of Horticulture and Forestry, Cook College, Rutgers- The State University, New Brunswick, NJ 08903 Gene B conditions precocious depletion of chlorophyll in fruits leading to precocious fruit yellowing. In addition, B can deplete chlorophyll in leaves at early stages of plant […]
Further Notes on the Silvery-Leaf Trait in Cucurbita
Cucurbit Genetics Cooperative Report 7:81-83 (article 36) 1984 Shifriss, O. Department of Horticulture and Forestry, Cook College, Rutgers University, New Brunswick, NJ 09803 The silvery-leaf trait (6) raises two issues: the biological control of its complex expression and its adaptive value. The biological control is poorly understood. But there is little doubt that, under field […]
Reflected Light Spectra from Silvery and Nonsilvery Leaves of Cucurbita pepo
Cucurbit Genetics Cooperative Report 6:89-90 (article 45) 1983 O. Shifriss1 Rutgers University, New Brunswick, NJ 08903 The silvery-leaf trait is conditioned by gene M. This gene can bring about a breakdown of intercellular cohesion in the upper tissue of the leaf, leading to air spaces between the palisade cells as well as between the palisade […]
On the Silvery-Leaf Trait in Cucurbita pepo L.
Cucurbit Genetics Cooperative Report Volume 5:48-50 (article 24) 1982 O. Shifriss Department of Horticulture and Forestry, Cook College, Rutgers University, New Brunswick, NJ 08903 Recent observations and breeding data suggest that there exists a silvery-leaf (SL) trait whose expression is subject of marked genetic and non-genetic variations, that the genetic variants include M / M for mottled leaves (2) […]
On White Cotyledons in Cucurbita pepo L.
Cucurbit Genetics Cooperative Report 5:39 (article 19) 1982 Helen Atthowe and O. Shifriss Department of Horticulture and Forestry, Cook College, Rutgers – the State University, New Brunswick, NJ 08903 In the fall of 1981, during a routine work of transplanting squash seedlings, one of us (H.A.) discovered that the lower side of the cotyledons of […]
The Derivatives of ‘Fordhook Zucchini’ and Their Breeding Value
Cucurbit Genetics Cooperative Report 4:46 (article 25) 1981 O. Shifriss Department of Horticulture and Forestry, Cook College, Rutgers University, New Brunswick, NJ 08903 A cultivar by the name Fordhook Zucchini (Cucurbita pepo L.) was introduced by W. Atlee Burpee Co. in 1942. According to available information, this cultivar was obtained from M. Herb of Naples, […]
On Coadaptation of Gene B in Cucurbita
Cucurbit Genetics Cooperative Report 4:32-33 (article 24) 1981 O. Shifriss Department of Horticulture and Forestry, Cook College, Rutgers University, New Brunswick, NJ 08903 Gene B conditions precocious fruit pigmentation in Cucurbita pepo and C. maxima. But this gene can also affect plant growth, sexuality, and fruit quality. Some of these effects are beneficial and others, […]
