Abstract
Artificial crossing experiments were made with three taxa of Ocimum. Plants ofO. forskolei Benth. andO. basilicum L. var. purpurascens Benth. were found to be interfertile, butO. americanum L. var.pilosum (Willd.) Paton was found to be reproductively isolated from the other two taxa. The new chromosome number 2n = 48 was counted inO. forskolei. These results suggest thatO. forskolei might be the closest relative of the Sweet Basil. The origin of the Sweet Basil is also discussed.
Résumé
Foram feitas experiências de cruzamento artificial com três taxas deOcimum. Plantas deO. forskolei Benth. eO. basilicum L. var.purpurascens Benth. eram inter-férteis, masO. americanum L. varpilosum (Willd.) Paton era reproductivamente isolada das outras duas taxas. Apresenta-se o número cromossomico 2n = 48 deO. forskolei pela primera vez. Estes resultados sugerem queO. forskolei pode ser o relativo mats próximo do Manjericão-Grande. Discute-se também a orginem do Manjericão- Grande.
