Subject(s): Online resources: In: Mansoura Unviersity Journal of Agricultural Sciences 2005.v.30(9)Summary: One hundred and six Brassica genotypes of four species i.e. B. nap us, B. juncea, B. campestris, B. carinata were evaluated for resistance to white rust (caused by Albugo candida) at seedling stage under controlled conditions (in greenhouse, under artificial epiphytotic conditions) and at adult stage under natural conditions, during the two successive growing seasons 2002/03 and 2003/04 in the experimental farm of Sakha Agricultural Research Station, Kafr EI-Sheikh, Egypt. At seedling stage, all B. napus lines (55 lines), 4 lines (B. campestris) and 3 lines (B. carinata) were completely resistant. Four lines of B. juncea were moderately resistant, while twenty lines of both B. juncea and B. campestris were moderately susceptible. The rest of the tested lines (B. juncea) were susceptible.
