Industry perspective, genetics and genomics of peanut blanchability Open
Blanching is the process of removing the testa or seed coat (skin) from peanuts, and a genotype's capacity to release its testa is referred to as its blanchability. The genotype, seed quality, harvest date, level of maturity, as well as th…

Determination of Polyphenol, Antioxidant Activity, and Individual Phenolic Compounds in Tubers of Sweet Potato Varieties Grown in South Carolina Open
The effect of varieties of sweet potato (Purple, Burgundy, Beaureguard and Porto Rico) grown in South Carolina on the antioxidant activity, polyphenol content, and individual phenolic compounds were tested. The sweet potato tuber shapes be…

Step-wise selection using high throughput phenotyping platform (HTTP) and stress tolerance indices as an approach for improving drought tolerance in groundnut (Arachis hypogaea L.) Open
Drought stress is a major production constraint of groundnut in Africa and Asia where it is largely grown as rainfed crop. The experiments aim to design an early testing approach for drought tolerance in the groundnut breeding pipeline to …

A cooperative scheme for late leaf spot estimation in peanut using UAV multispectral images Open
In Australia, peanuts are mainly grown in Queensland with tropical and subtropical climates. The most common foliar disease that poses a severe threat to quality peanut production is late leaf spot (LLS). Unmanned aerial vehicles (UAVs) ha…

Development of a Rapid Phenotyping Method to Screen for <i>Didymella arachidicola</i> Resistance in Peanuts Open
Net or web blotch (NB), caused by Didymella arachidicola, is an emerging threat causing a significant reduction in yield of peanuts in cooler production regions globally, including Australia, China, and Southern Africa. Host resistance aga…

Peanut yield prediction with UAV multispectral imagery using a cooperative machine learning approach Open
The unmanned aerial vehicle (UAV), as a remote sensing platform, has attracted many researchers in precision agriculture because of its operational flexibility and capability of producing high spatial and temporal resolution images of agr…

De novo QTL-seq Identifies Loci Linked to Blanchability in Peanut (Arachis hypogaea) and Refines Previously Identified QTL with Low Coverage Sequence Open
Blanchability is an often overlooked, but important trait for peanut breeding. The process of blanching, removing the skin, is an important step in the processing of raw nuts for manufacturing. Under strong genetic control and requiring co…

Legacy genetics of <i>Arachis cardenasii</i> in the peanut crop shows the profound benefits of international seed exchange Open
Significance A great challenge for humanity is feeding its growing population while minimizing ecosystem damage and climate change. Here, we uncover the global benefits arising from the introduction of one wild species accession to peanut-…

Accurate analysis of short read sequencing in complex genomes: A case study using QTL-seq to target blanchability in peanut (<i>Arachis hypogaea</i>) Open
Next Generation sequencing was a step change for molecular genetics and genomics. Illumina sequencing in particular still provides substantial value to animal and plant genomics. A simple yet powerful technique, referred to as QTL sequenci…

Evaluation of linkage disequilibrium, population structure, and genetic diversity in the U.S. peanut mini core collection Open
Based on GWA, population structure as well as additional simulation results, we find that the primary limitations of this collection for GWAS are a small collection size, significant remaining structure/genetic similarity and long LD block…
