Abstract
Of the 49 germ plasm lines/cultivars screened against YMY in a disease screening nursery, none of the cultivars was found to be immune or resistant. However, five cultivars (MRI M-B, MRI M-26, MRI M-27, MRI M-196 and MRI M-202) were found to be moderately resistant. The remaining cultivars were moderately to highly susceptible. Among the same test lines screened against LCY in another disease screening nursery, cultivar MRI M-1 and MRI M-35 were proved to be immune and highly resistant, respectively. Ten cultivars were resistant while thirty one were moderately resistant.
