A recently published study refers to the possibility that the present cultivated watermelons in the world might have originated from Kordofan in Sudan, where a closest relative of the present day’s watermelons is found in a white-pulped watermelon form grown in Kordofan in Sudan, where this crop has been grown there for long to produce melon seeds and for other uses. It is worth mentioning here that the Agricultural Plant Genetic Resources Conservation and Research Centre (APGRC) in the ARC, Sudan has already collected and is conserving several hundreds of accessions from local genetic resources of watermelon from Kordofan region and elsewhere, including as well a number of wild related types.
