Agronomic and Grade Characteristics of the Virginia-Type Peanut Grown in Virginia – Carolina Region.

This study examines the genotype × environment interaction for yield and grade characteristics of 48 commercial varieties and advanced breeding lines of Virginia-type peanut. These genotypes include the most recent cultivars and lines of the North Carolina State University and Virginia Tech peanut breeding programs. Field experiments were conducted in 2008 at five locations in Virginia, North Carolina and South Carolina, over a wide range of soil types and weather conditions. Genotypes produced average pod yields from 4895 to 6705 kg/ha, depending on location. Genotype and location had a significant interactive effect on the content of extra large kernels, fancy pods, and pod brightness. However, the genotype × environment interaction was not significant for yield and grade characteristics for Bailey, CHAMPS, VT 004152, and other several lines. Results indicate that genetic variability for yield and grade characteristics exists in the Virginia-type peanut germplasm, and that stable yields across a large production area can be achieved through breeding and selection.
