“…The observed difference between the dehulled seed and seed coat indicates that, the distribution of carbohydrate in the seed tend to concentrate much in the seed coat than the dehulled seed. The values for the dehulled seed and seed coat are however comparable to Africa oil bean seed (19.2%) (Osagie et al, 1986), African walnut (19.8%) (Odunsua and Adebona, 1983) and higher than that of water melon (10.96%) (Oyolu, 1977) and pumpkin seed (7.6%) (Farinu, 1986). Generally, the samples have high energy value in the order: dehulled seed > whole seed > seed coat.…”

Whole seeds, dehulled seeds and seed coats of bottle gourd seed (Lagenaria siceraria) were analysed for their proximate, amino acids and mineral compositions. The results of the analysis showed that, whole seed has highest content of moisture (17.5 ± 0.21%) and ash (5.80 ± 0.83%) while dehulled had highest amount of crude protein (35.0 ± 0.48%) and crude lipid (39.22 ± 1.48%) and seed coat contain highest amount of crude fiber (59.05 ± 0.98%). The study showed a profile of seventeen amino acids (isoleucine, leucine, lysine, methionine, cysteine, phenylalanine, tyrosine, threonine, valine, alanine, arginine, aspartic acid, glutamic acid, glycine, histidine, proline and serine) with glutamic acid, leucine and aspartic acid being the predominant amino acid. The percentages (%) of essential and non-essential amino acids in dehulled seeds, whole seeds and seed coats were 44 vs 56, 41 vs 59 and 51 vs 49 respectively. The dehulled seeds contained essential amino acids that were found to be higher than WHO/FAO/UNU requirement. In whole seeds, threonine, lysine and lysine were found to be the most limiting amino acids. Seed coats were deficient in all the essential amino acids except for valine. Generally, the mineral composition of the seed was found to be relatively high, indicating the seed to be a good source of dietary elements, except for Ca, Zn, Co and Cr where very low values were obtained. Finally, the results of the study indicate that, bottle gourd seed is a potential source of protein, lipid, micro and macronutrients, and if properly utilised, could contribute in solving the problem of malnutrition and also serve as raw material for agro-based industries.

“…Some authors had mistaken it for Citrullus colocynthis Schrad, which is a wild species of the cucurbitaceae growing in Morocco, Algeria, the Sahara desert and India (Abu-Nasr and Pott, 1953). In order to check this confusion, the use of the name Colocynthis citrullus together with the vernacular name "Egusi" was recommended to represent this crop (Oyolu, 1977). Egusi melon originated in Africa and has been cultivated in the drier part of the continent for many centuries (Cobley, 1951).…”

“…The seeds (kernels) are eaten in various forms. They are rich in protein, fat and vitamins A, B1, B2 and C. However, the fruit is not edible because of its bitter and hard flesh (Ntui and Uyoh 2005;Gusmini et al 2004;Purseglove 1991;Oyulu 1977). The importance of ''Egusi'' crop has also been raised under various circumstances by other authors such as Schippers (2000Schippers ( , 2004 and Vodouhe et al (2001) as a weed control plant, and as an alternative source of fuel (Giwa et al 2009).…”

Cotyledonary explants of two ''Egusi'' genotypes, 'Ejagham' and NHC1-130, were co-cultivated with Agrobacterium tumefaciens strain EHA101 carrying either plasmid pIG121-Hm harbouring genes coding for betaglucuronidase (gus), hygromycin phosphotransferase (hpt) and neomycin phosphotransferase II (nptII) or plasmid pBBRacdS harbouring these same genes along with a gene coding for 1-aminocyclopropane-1-carboxylate (ACC) deaminase. Six weeks after co-cultivation, more than 35% of explants produced shoots in both cultivars. A DNA fragment corresponding to the gus gene or the selection marker nptII was amplified from genomic DNA extracted from leaves of regenerated plant clones rooted on hormone-free MS medium containing 100 mg/l kanamycin, suggesting their transgenic nature. Southern blot analysis confirmed successful integration of one to three copies of the gus gene. Transformation efficiencies of cultivar NHC1-130 with EHA101(pIG121-Hm) and EHA101 (pIG121-Hm, pBBRacdS) were 3.8% and 10%, respectively, which were higher than those obtained for cultivar 'Ejagham' of 2.4% and 5.7%, respectively. Co-cultivation medium containing 5 mg/l BA was effective for obtaining high transformation efficiency for both cultivars as compared with that without it.
