Ivorian Cucurbitaceae seeds consumed in sauce find themselves in several varieties. Among the Cucurbitaceae, Citrullus lanatus species comprises four cultivars listed on the basis of the size and appearance of seeds (oval seed cultivar, large seed cultivar, average seed cultivar and small seed cultivar). To promote these crops, field trials in situ were carried out to show the diversity within the species. Works have been conducted on the characterization of physico-chemical properties of seeds, and almonds. The agromorphological analysis showed different fruits weight of 1135.45 ± 266.78 g, 1075.29 ± 336.89 g, 838.43 ± 184.15 g and 764.4 ± 242.3 g for COS, CBS, CAS and CSS cultivars respectively. The morphological characteristics of peeled seeds (almonds) and not peeled (whole seeds) varied significantly (P 0,05) of a cultivar to the other. The percentage of germination of seeds showed a significant difference (p 0,05) from a cultivar to the other one. So the percentages of germination were 62,81 % and 88,88 % for the cultivars CSS and CAS respectively. As for cultivars COS and CBS, the percentages of germination were 95,72 % and 90,72 %. The qualitative and quantitative evaluation of the characteristics of the seeds of Citrullus lanatus cultivars showed that cultivars CBS and COS were premature, produced big fruits containing big seeds contrary to the late cultivars CAS and CSS with small and average seeds. However, the shape of fruits of the various cultivars did not determine the size of their seeds.
