Journal Title: International Journal of Agriculture Sciences - Year 2016, Vol 8, Issue 42
Abstract
Black spot and powdery mildew are the two important rose diseases worldwide and affects nearly all existing cultivars. Black spot and powdery mildew resistance in the field was visually evaluated for a total of thirty six rose cultivars at SKUAST-K. Shalimar, Srinagar. Out of 36 cultivars screened for black spot, nineteen cultivars were tolerant in reaction. Remaining cultivars were highly susceptible in reaction. While in case of powdery mildew disease nineteen cultivars were found tolerant, two cultivars as moderately tolerant namely Chrysler imperial, Christian Dior and rest of the cultivars which include First red, Golden harvest, Golden gate, Himachal red, Konfitti, and cover girl were either susceptible or highly susceptible in reaction.
