چکیده

An unusual seed mutant in watermelon (Citrullus lanatus var. lanatus) has seeds with a fleshy pericarp, commonly called egusi seeds. The origin of the phenotype is unknown, but it is widely cultivated in Nigeria for the high protein and carbohydrate content of the edible seeds. Egusi seeds have a thick, fleshy pericarp that appears during the second to third week of fruit development. We studied the inheritance of this phenotype in crosses of normal seeded Charleston Gray and Calhoun Gray with two plant introduction accessions, PI 490383w and PI 560006, having the egusi seed type. We found that the egusi seed type is controlled by a single recessive gene, and the symbol eg was assigned.

Inheritance of resistance to zucchini yellow mosaic virus and watermelon mosaic virus in watermelon.

High resistance to zucchini yellow mosaic virus-China strain (ZYMV-CH) and moderate resistance to watermelon mosaic virus (WMV) were found in a selection of PI 595203 (Citrullus lanatus var. lanatus), an Egusi type originally collected in Nigeria. Mixed inoculations showed primarily that these two viruses have no cross-protection. This fact may explain the high frequency of mixed infection ofte...

UNDERLYING HORTICULTURALLY IMPORTANT TRAITS IN WATERMELON by JASON MICHAEL PROTHRO (Under the Direction of Cecilia McGregor) ABSTRACT QTL analysis was performed for multiple traits in an elite x egusi and an elite x citron F2 population of watermelon (Citrullus lanatus var. lanatus Thunb.). Two linkage maps were constructed for QTL analysis using single nucleotide polymorphism (SNP) markers. A ...

Estimation of Some Anti-nutritional Factors in Oil-Free Seed Cake of Egusi

In this study, some anti-nutritional factors present in oil-free seeds of egusi (Citrullus colocynthis L.) seed cake were determined. Oil was extracted from the oil-free egusi seed by the Soxhlet extraction method. The anti-nutritional factors were determined using the standard methods. The result of anti-nutritional factors analysis revealed that the seed contains phytate (3.09 ± 0.65mg/100g),...

The Genes of Watermelon

Watermelon [Citrullus lanatus (Thunb.) Matsum. & Nakai] is a major vegetable crop in the world, accounting for 6.8% of the world area devoted to vegetable crops. Watermelon is a useful vegetable crop for genetic research because of its small genome size, and the many available gene mutants. The watermelon genes were originally organized and summarized in 1944, and have been expanded and updated...
