- Abstract
Isolates of P. halstedii collected from different parts of Karnataka, Maharashtra and Andhra Pradesh belong to a single race, i.e., race 100. Based on virulence pattern, they can be grouped into five different groups, A, B, C, D and E. Bangalore isolate was most virulent and Bidar isolate was least virulent. Morphological variations existed among the isolates with regard to the size of sporangiophores and sporangia. Sporangiophores were longer Dharwad isolate and sporangia were larger in Mysore and Latur isolates.
