Titre : Integration of Breeding and Agronomic Approaches for Improvement of Drought Tolerance and Water Use Efficiency in Peanut Production

Identification : 6044-21000-005-03-R

Pays : Etats Unis

Durée : Start Date : Oct 1, 2017 // End Date : Apr 30, 2021

Location : National Peanut Research Laboratory : Dawson, GA

Objectifs
Develop near-term solutions that can be implemented by peanut producers to mitigate drought ; improve water use efficiency and improve environmental footprint of peanut production. The research involves an integrated approach to developing peanut cultivars or germplasm lines with resistance to drought stresses and also seeks to elucidate the underlying mechanisms of drought response. The objectives of the proposal are to : 1) characterize physiological and molecular traits of the U.S. peanut mini-core collection and select breeding lines for identification of drought tolerant genotypes ; 2) identify key molecular and biochemical components of drought response regulation system(s) in peanut ; and 3) develop irrigation schemes that enhance water use efficacy, complement nutrient acquisition, maintain or improve yield and quality with the best economic returns for drought tolerance cultivars/breeding lines.
