Banana variants

In this study, RAPD fingerprinting has been carried out for variants selected from orchards growing with micropropagated Robusta banana (Musa spp. ‘AAA’) plants. After isolation of quality DNA and preliminary screening of random primers, fourteen arbitrary (10-mers) primers showing intense unambiguous and reproducible PCR amplification have been selected for study. Among them OPA-19 and OPC-03 showed only monomorphic bands while OPA-02, OPA-09, OPA-13, OPA-14, OPB-6, OPB-15, OPC-01, OPD-10, OPF-04 and OPF-12 primers showed polymorphic bands.

Banana and plantains is the most important tropical fruit crop in the world, which serves as a major food and source of income in many countries. Bananas are severely infected by several pathogens one such Fusarium oxysoporum f. sp. Cubense which causes significant crop losses in the fields. In this study fusarium wilt screening was carried out on chemically induced mutants and molecular analysis was done to assess the acquired resistance to Fusarium oxysoporum f. sp. cubense.

Tissue culture regenerated materials of Musa L. spp. (banana and plantain) along with their somaclonal variants were assessed for karyotype abnormalities to be used as indicators for rapid cytological marking. The results show that although slight variations were noted in karyomorphometric characters, like chromosome number, arm length, total chromosome length, and total chromosome volume, these were not significant (P ≤ 0.05).
