BULGARIAN LANDRACES AND LINES OF COMMON BEAN (PHASEOLUS VULGARIS L.) WITH PHYSIOLOGICAL RESISTANCE TO WHITE MOLD

摘要

White mold (WM) caused by Sclerotinia sclerotiorum (Lib.) de Bary is one of the most harmful diseases on a number of crops, including common bean. Its harmful effect on bean is affected by the growth habit, crop production practice and by the physiological resistance of the cultivars (Schwartz et al., 1987). Combining physiological resistance with mechanisms for prevention of infection and pathogen development (erect plant, open plant canopy) is the current breeding strategy for minimizing yield losses due to white mold in common bean (Miklas et al., 2000).
