Abstract

Mycosphaerella musicola produces various toxins known to play a key role in pathogenicity and disease development. In our study secondary metabolites produced by M .musicola was extracted and investigated using different parameters. The investigation was aimed to understand the phytotoxic resistance of locally growing different Musa genotypes (AB-Elakki (ELA), AAA-G9 (G9) and AAB-Nanjangud Rasa Baley (NRB)) against the crude extract and partially purified lipophilic TLC fractions extracted from the culture filtrates of M. musicola. Susceptible and resistant banana genotypes against the crude extract and partially purified fractions were analyzed by electrolyte leakage assay and leaf puncher assay. The results revealed that the crude extract and TLC fractions showed varied phytotoxicity among the banana leaves belonging to different age groups and different genotypes. Phytotoxicity studies allowed us to observe that ELA and G9 exhibited resistance to crude extract and TLC fractions, indicating that these genotypes are resistant to initial M. musicola infection.
