Studies on Pathogen Variability in Blackgram root rot by Macrophomina phaseolina
Priyadharshini Bhupathi and M Theradimani
Blackgram is subjected to different biotic constraints, root rot being the serious one. The root rot pathogen Macrophomina phaseolina was isolated from the diseased stems and roots of blackgram collected from seven different places of Tamil Nadu. Among the seven isolates screened, K2m7 collected from Kallipatti in Namakkal district was identified as a virulent culture. Variability among the seven M.phaseolina isolates analyzed by RAPD-PCR technique, grouped them into two clusters. Cluser A had six isolates and cluster B had one isolate.
