Improvement of Genetic Resistance to Multiple Biotic and Abiotic Stresses in Peanut

Peanut Genetic Streesses

United States Department of Agriculture (USDA) Agricultural Research Service (ARS)

Titre : Improvement of Genetic Resistance to Multiple Biotic and Abiotic Stresses in Peanut

Identification : 6048-21000-028-00-D

Pays : Etats Unis

Durée : Start Date : Feb 28, 2018 // End Date : Feb 27, 2023

Location : Crop Genetics and Breeding Research : Tifton, GA

Objectifs
1. Elucidate the interactions of responses in peanut to multiple biotic and abiotic stress factors, such as drought, tomato spotted wilt virus, leaf spots, white mold, and root-knot nematode ; determine overlapping response pathways ; discover selection targets (genes or networks) ; and work with breeders to use the information in developing peanut varieties with broad spectrum stress resistance/tolerance. 1A. Develop next-generation fine-mapping population segregating multiple traits of interest, such as Multi-parent Advanced Generation Inter-Cross (MAGIC), and conduct phenotypes in the field. 1B. Construct high resolution genetic and trait maps using single nucleotide polymorphism (SNP) markers for fine-mapping of QTLs/markers linked to the traits of interest. 1C. Apply molecular markers in breeding and trait stacking/pyramiding to develop superior lines of peanut using Marker Assisted Recurrent Selection (MARS) breeding scheme.
