Screen wild pepper accessions for resistance against concurrent mixed infections of pepper huasteco virus and pepper golden mosaic virus.
Inoculated 48 wild pepper plants (Capsicum annuum and Capsicum chinense accessions) with an equal mixture of pepper huasteco virus and pepper golden mosaic virus DNAs using biolistic bombardment.
Grafted plants that remained symptomless after biolistic inoculation to further challenge and evaluate resistance.
Half of the inoculated plants (24 of 48) demonstrated high susceptibility, while the remaining 24 individuals displayed varying levels of viral resistance.
Among resistant plants, eight remained completely asymptomatic with low levels of both viral DNAs, two showed symptoms delayed by 34 days coinciding with rising pepper huasteco virus DNA, and 14 exhibited symptom remission in new leaves at 31 days postinoculation alongside reduced viral DNA.

Implication

Experimental inoculation reveals variable resistance to dual geminivirus infection in wild Capsicum accessions, suggesting viral movement constraints restrict disease progression.
