Abstract
Influence of weather conditions on downy mildew and Ascochyta blight development on 12 pea genotypes, cultivated in Central Poland was examined in 1990-2000. Plants were somewhat more infected by Peronospora viciae f.sp. pisi than by Ascochyta complex fungi. Standard cultivars were less infected than breeding lines. Two periods of higher (1990, 1991 and 1995-1997) and two of lower (1992-1994 and 1998-2000) disease intensity were noted during 11 years of testing.
