Abstract
Page(s): 5 (2), 158- 163, 3 Ref.Onion seedlings of three cultivars; namely, "Saggai", "Dongola" and "Texas Early Grano 502", were inoculated with VAM, OYDV and both VAM and OYDV. The results indicated that "Texas Early Grano 502" was resistant to the virus, while "Saggai" and "Dongola" were susceptible. The VAM inoculation significantly improved some of the growth, yield and quality of "Dongola". In mixed infection with OYDV, VAM caused pronounced enhancement in these components over the virus-infected onion plants. Similarly, "Saggai" infected with OYDV responded significantly to VAM inoculation, whereas "Texas Early Grano 502" did not benefit from this interaction, in the presence or absence of OYDV infection.Khartoum University Pres
