Chocolate spot (Botrytis fabae) is a devastating disease of faba bean and reduces its production and productivity. Three controlled condition experiments were conducted to assess the effect of temperature on growth and sporulation of B. fabae, and faba bean resistance reaction against the pathogen using a single B. fabae isolate and Degaga and Bulga-70 faba bean varieties. For cultural experiment, a circular block of actively growing B. fabae mycelia was placed on faba bean dextrose agar medium and arranged in a completely randomized design (CRD) with four replications. For resistance reaction evaluation, fresh culture of isolate suspension was prepared (2 × 105 spores ml-1) and inoculated on to three weeks-old faba bean seedling detached leaves and the whole plant. Inoculated leaflets and seedlings were factorial arranged in a CRD with four replications. Both s.. View More»
