Shoot Regeneration from Immature Cotyledons of Watermelon

Cucurbit Genetics Cooperative Report 17:111-115 (article 33) 1994 X.P. Zhang, B.B. Rhodes and J.W. Adelberg Department of Horticulture, E-142 Poole Agricultural Center, Clemson University, Clemson, SC 29634-0375 Genetic transformation and somaclonal variation can be efficient alternatives to traditional breeding techniques for varietal improvement. However, an efficient regeneration system is essential for in vitro techniques to […]

Screening for Resistance to Anthracnose (Race 2), Gummy Stem Blight, and Root Knot Nematode in Watermelon Germplasm

Cucurbit Genetics Cooperative Report 17:106-110 (article 32) 1994 G.E. Boylan, J.D. Norton and B.R. Abrahams Department of Horticulture, Alabama Agricultural Experiment Station, Auburn University, AL 36849 Over the past six years Auburn University has increased watermelon germplasm for the USDA-ARS. This germplasm has been routinely screened for resistance to gummy stem blight, root knot nematodes […]

Determination of Watermelon Ploidy Level using Flow Cytometry

Cucurbit Genetics Cooperative Report 17:102-105 (article 31) 1994 X.P. Zhang and B.N. Rhodes; J.F. Whitesides Horticulture Department, Clemson University, Clemson, SC 29634-0375, Department of Poultry Science, Clemson University, Clemson, SC 29634-0379 Several approaches have been used to identify ploidy level in watermelon, citrullus lanatus. Generally, ploidy levels are suggested by plant morphology, leaf shape/size, pollen […]

A New Morphological Marker in Watermelon, Juvenile Albino (ja)

Cucurbit Genetics Cooperative Report 17:101 (article 30) 1994 Xingping Zhang and Bill Rhodes Horticulture Department, Box 340375, Clemson University, Clemson, Sc 29634-0375 In 1992, a new morphological variant, which we name “juvenile albino” (ja) was observed in two populations – selfed ‘Dixilee’ and an F2 population of G17AB (ms ms) x ‘Dixilee’. To our knowledge, […]

The Crossability of Cucumis melo and C. metuliferus, an Investigation of In Vivo Pollen Tube Growth

Cucurbit Genetics Cooperative Report 17:97-100 (article 29) 1994 A. Beharav and Y. Cohen Bar-Ilan University, Dept. of Life Sciences, Ramat Gan 52900, ISRAEL For many years viral disease in muskmelon (Cucumis melo) (2n=24) has not been of great concern to seedmen and growers (8). The development of resistant cultivars can eliminate the disease. Various accessions […]

Effect of Gamma-Radiation on vitality and Fertilization Ability of Cucumis melo and C. metuliferus Pollen

Cucurbit Genetics Cooperative Report 17:94-96 (article 28) 1994 A. Beharav and Y. Cohen Bar-Illan University, Dept. of Life Sciences, Ramat Gan 52900, ISRAEL The mentor pollen technique can be applied to overcome crossing barriers in certain interspecific hybridization, where pollen tube growth is arrested before the ovary (4). Oost and Den Nijs (3) reported on […]

Attempts to Overcome Barrier of Interspecific Hybridization between Cucumis melo and C. metuliferus

Cucurbit Genetics Cooperative Report 17:90-93 (article 27) 1994 A. Beharav and Y. Cohen Bar-Ilan University, Dept. of Life Sciences, Ramat Gan 52900, ISRAEL Our efforts to achieve the interspecific hybrid between Cucumis melo and Cucumis metuliferus through conventional breeding procedure between a few reciprocal combinations (in summer 1002) were unsuccessful because of the existence of […]
