Interpretive Summary:

Technical Abstract: The Andean Diversity Panel was evaluated for response to inoculation with charcoal rot in a field trial in Isabela, Puerto Rico in 2012. The trial was inoculated with backpack sprayers at flowering and a visual evaluation was conducted three weeks later. There was a broad range of response, with about 20 genotypes out of 392 showing resistant reactions. Association mapping analysis indicated a genomic region on Pv09 associated with resistance.
