Nufar basil (Ocimum basilicum "Nufar") is the first variety of Genovese basil (O. basilicum "Genovese") that is resistant to fusarium wilt. Fusarium wilt is a disease that causes sudden wilting and death in basil. It is caused by the fungus Fusarium oxysporum f. sp. basilicum, which attacks the xylem in the stem, blocking water uptake and leading to a characteristic sudden leaf wilt that does not respond to watering. [1] Nufar basil is resistant to fusarium wilt, remaining asymptomatic even when infected. It was developed in 2006 in Israel by the breeders of the Agricultural Research Organization, and commercialized by Genesis Seeds.[2]
