Evaluation and Enhancement of Virus Resistant Snap Beans

Abstract

Aphid-transmitted viruses have caused devastating yield losses in snap bean production regions of NY in the last 5 years. Cucumber mosaic virus (CMV) appears in almost 100% of infected fields; however, bean yellow mosaic virus and clover yellow vein virus are also prevalent. Chemicals are ineffective, as aphids do not life-cycle on snap beans, leaving host-plant resistance as the only viable approach to managing these viruses.
