Abstract

Inheritance of resistance to anthracnose at fruiting and seedling stages was studied in two F₂ populations from a cross between Capsicum annuum cv. 'Bangchang' and Capsicum chinense'PBC932'. The first F₂ was used to study anthracnose resistance at fruiting stage on mature green and ripe red fruit, and the second F₂ was used to study the resistance at both seedling and fruiting stages. Fruit inoculation was performed on detached fruit using a microinjector. Disease severity was assessed on a 0-9 scale at 7 days after inoculation. Seedling inoculation was performed using a drop method on detached leaves of 4-week-old seedlings. Disease severity was assessed on a 1-9 scale at 3 days after inocu..
