Pumpkin (Cucurbita moschata) is ranked as one of the least economic important vegetable crops in Sudan despite having high nutritive values and great industrial uses. It is grown in small holdings along rivers banks. The crop is threatened by damage caused by powdery mildew, Zucchini yellow mosaic virus (Sid Ahmed et al., 2003) and fruit […]

Two Cucurbita moschata Bush-Parthenocarpic Breeding Lines Through an Interspecific Cross
Cucurbita moschata varieties in Korea have soft flesh when their immature fruits are panbroiled. Their vine growth habit hinders wide cultivation in the greenhouse. Zucchini varieties belonging to Cucurbita pepo have bush growth habit but a little hard flesh when their immature fruits are done. These species are generally non-parthenocarpic although the latter species has […]
Morphological Variability and Phenotypic Association among Pairs of Characters of some Watermelon chlorotic stunt virus Resistant Lines of Citrullus lanatus Thunb.
Twelve lines of watermelon (Citrullus lanatus Thunb.) with resistance to Watermelon chlorotic stunt virus (WCSV) were morphologically characterized and association among pairs of characteristics was estimated. These watermelon lines were developed at the National Institute for Promotion of Horticultural Exports-University of Gezira-Sudan. Wide differences exist among these lines with respect to vegetative, inflorescence, fruit and […]
Histological Studies of Colletotrichum orbiculare on the Susceptible and Resistant Cucumber Cultivars
The infection process of Colletotrichum orbiculare on the leaves of susceptible and resistant cucumber cultivars were studied histologically. On both cultivars, conidia began to germinate 8 h after inoculation (hai) and formed appressoria. Then melanised appressoria formed penetration pegs at 10 hai. On the susceptible cultivar, infection vesicles formed within 24 hai and developed thick, […]

2012 to 2013 Watermelon Reports
Watermelon (Citrullus lanatus) Morphological Variability and Phenotypic Association among Pairs of Characters of some Watermelon chlorotic stunt virus Resistant Lines of Citrullus lanatus Thunb.

Infection Process of Sphaerotheca fuliginea on Host Cucumber and on host Wheat Leaves
The infection process of Sphaerotheca fuliginea into epidermal cells of host cucumber and nonhost wheat were studied histochemically. The percentages of germinated conidia had no significant difference on cucumber and wheat leaves at the pre-penetration stage. When S. fuliginea overcame the constitutive barriers of wheat leaf, papillae and hypersensitive reaction were induced to prevent the […]
2012 Gene List for Watermelon
by Todd C. Wehner Department of Horticultural Science North Carolina State University Raleigh, NC 27695-7609 Introduction Watermelon (Citrullus lanatus (Thunb.) Matsum. & Nakai) is a major cucurbit crop that accounts for 6.8% of the world area devoted to vegetable crops (FAO, 2002). Watermelon is grown for its fleshy, juicy, and sweet fruit. Mostly eaten fresh, they […]
