Overview

Major yield losses frequently occur in peanut (30 to 50%) in South America and the Oceania countries of Southeast Asia. Losses are often due to severe problems with foliar and soilborne pathogens and insect-vectored viruses. Soil insects are also a common production constraint. Locally adapted cultivars incorporating multiple-pest resistance would reduce direct losses to these pests. Development of cultivars with multiple-pest resistance is the most practical means to a more reliable, environmentally-friendly peanut production system.
