Peanut (Arachis hypogaea L.) is an important oilseed, cash crop grown worldwide mainly in a tropical and subtropical climate. Drought stress (DS) is one of the serious abiotic stresses that alter the morphological, physiological, biochemical and molecular responses of plants and causes huge production loss across the globe. The aim of this study, to investigate the twenty widely grown Korean genotypes at the seedling stage under the control and drought stress conditions, to identify tolerant lines as well as related traits. In addition, the influence of DS and rehydration or recovery after stress on peanut genotypes was also studied. Initial screening showed that given genotypes had a differential response to DS, demonstrating a wide range of variation in tested peanut genotypes during the seedling stage towards the DS. Further, based on investigation of the different growth attributes and biochemical assessment six genotypes (Palkwang, Milkwang, and Daekwang) and (Daekwang, Haeol, and Heukhwaseang) were observed as drought-tolerant and drought-sensitive lines respectively. The findings of this study will aid in the selection of peanut genotypes in future breeding efforts aimed at improving drought tolerance and minimizing peanut production loss.

Peanut variety identification is essential for protecting the intellectual property rights of researchers, ensuring qualitymanagement for producers, and safeguarding the interests of seed production stakeholders. In this research, we developed a molecularmarker set for peanut variety identification using single nucleotide polymorphism (SNP) markers. We used genotyping data andselection procedures, including decision tree and optimal combination selection, to identify a minimal set of informative SNP sites. These SNPs were then converted into Kompetitive allele-specific PCR (KASP) markers. We selected a subset of 14 informative SNPsfrom a pool of 22 candidate markers, representing the minimum number of combinations required to distinguish cultivars. SNPsobtained from the microarrays were converted to KASP markers and then evaluated across 51 peanut varieties. The developed markerset, which consists of a minimal number of markers, is expected to be a rapid and cost-effective tool for peanut variety identification.
