| Summary: |
Yellow passion fruit (Passiflora edulis Sims) yield and longevity have
been drastically reduced by bacterial spot (Xanthomonas axonopodis pv. passiflorae - Xap) and passion fruit woodiness disease (PWD) (Cowpea aphid-borne
mosaic virus - CABMV). This study was aimed at evaluating the reaction of 11
genotypes of yellow passion fruit, based on the reaction of their progenies, to
both mechanically inoculated Xap and CABMV, under greenhouse conditions.
There was a progressive increase in bacterial spot and PWD severity with
time. BRS Gigante Amarelo, MAR20#12, and MAR20#34 were selected as the
progenies with lowest bacterial spot severity and disease progress over time.
MAR20#2005, EC-L-7, UnB2015-1, and EC-3-0 presented the lowest PWD severity
and disease progress over time. These progenies, along with individual plants
from other progenies in which disease severity was significantly low until the
last evaluation, will be cloned and tested again for Xap and CABMV, including
other isolates. |
