Abstract: Cross-breeding is a method of producing progeny with better resistance to
pathogens. Resistance to pathogens usually involves pathogenesis-related (PR) proteins.
Class II chitinase is an example of a defensive PR protein in plants. The class II chitinase
in chilli is coded by the CaChi2 gene. In this study, we crossed susceptible with resistant
chilli cultivars, analysed the F1 resistance response against pathogenic F. oxysporum, and
analysed the level of CaChi2 gene expression in the F1. Data were collected using disease
severity index (DSI) determination and gene expression analysis by qRT-PCR (quantitative
Reverse Transcriptase Polymerase Chain Reaction). Results showed that the DSI of F1 was
not significantly different from the resistant ancestor. The relative CaChi2 expression level of
F1 was higher than the susceptible ancestor but not significantly different from the resistant
ancestor. We concluded that the F1 can be categorised as resistant to F. oxysporum, and
the CaChi2 gene is involved in the molecular defense response.
