In Uganda passion fruit woodiness disease (PWD) damages
passion fruit, causing yield losses of 60-100%. This study aimed
at detecting and screening yellow and sweet calabash passion
fruit for resistance to PWD. Four viruses, namely, Cowpea
aphid borne mosaic virus, Cucumber mosaic virus,
Passiflora latent virus, and Tomato ringspot virus were
detected using ELISA. Only Cowpea Aphid borne mosaic
virus showed a weak reactivity with antiserum, indicating its
presence in the tested samples in low concentrations. The
detected virus was used to mechanically inoculate yellow and
sweet calabash to observe symptom development. This is still
on-going.
