Abstract
Sixty-one isolates of Macrophomina phaseolina were isolated and studied for their adaptability to different temperature and pH. Higher relative growth rate was observed at 30oC followed by 35oC. Similarly, Higher mean dry mycelial weight at pH 6 and 7, clearly indicated the preference of isolates to particular range of pH. Different nitrogen sources were found to have a significant effect (p?0.01) on the physiology of M + and M isolates of M. phaseolina.
