Genotyping-by-Sequencing Based Genetic Mapping Identified Major and Consistent Genomic Regions for Productivity and Quality Traits in Peanut

Abstract: With an objective of identifying the genomic regions for productivity and quality traits in peanut, a recombinant inbred line (RIL) population developed from an elite variety, TMV 2 and its ethyl methane sulfonate (EMS)-derived mutant was phenotyped over six seasons and genotyped with genotyping-by-sequencing (GBS), Arachis hypogaea transposable element (AhTE) and simple sequence repeats (SSR) markers. The genetic map with 700 markers spanning 2,438.1 cM was employed for quantitative trait loci (QTL) analysis … Show more

“…Of the ve major QTL, four were clustered in two genomic regions; a 24.5 cM region on Ah12 chromosome with 300 predicted genes carried one QTL each for VCR90 and SCMR90, and a 19 cM region on chromosome Ah13 with 259 predicted genes carried one QTL each for VCR90 and SCMR30. The cluster 2 on Ah13 was consistent as it was also identi ed for VCR90 by Pattanashetti et al (2020), while Pandey et al (2021) identi ed a QTL cluster on Ah13 for VCR30, SCMR60 and SCMR90. These regions can be the targets for further ne-mapping.…”

“…Recent genomics studies using the RIL population of TAG 24 × ICGV 86031 and a map of 191 SSR markers identi ed two major QTLs for VCR with the highest PVE of 31.8% and a single major QTL for SCMR with a PVE of 11.0% (Pattanashetti et al 2020). Subsequently, Pandey et al (2021) improved the genetic map for TAG 24 × ICGV 86031 using 1028 SNP loci genotyped with a high-density 58K "Axiom_Arachis" array and 177 SSR markers. The genome-wide QTL analysis identi ed a single major main-effect QTL for VCR with a PVE of 33.9% and two major main-effect QTLs for SCMR with the highest PVE of 22.4%.…”

“…Cultivated peanut is widely known as an essential oilseed, protein-enrich food crop worldwide and retains important breeding traits during domestication (Zhuang et al, 2019;Bohra et al, 2022). Even so, peanut production is still substantially influenced by numerous biotic and abiotic factors (Agarwal et al, 2018;Gangurde et al, 2020Gangurde et al, , 2021Kumar et al, 2020;Shasidhar et al, 2020;Sinha et al, 2020;Jadhav et al, 2021;Pandey et al, 2021;Soni et al, 2021;Aravind et al, 2022;Bomireddy et al, 2022;Liu et al, 2022;Patel et al, 2022). When plants are exposed to diverse abiotic and biotic factors, APX enzyme as a primary marker can quickly eliminate unnecessary H 2 O 2 (i.e., ROS scavenging) from plant cells by adjusting several physiological and biochemical activities to safeguard cells from the noxiousness of overproduction of ROS (Das and Roychoudhury, 2014;Mittler, 2017;Hasanuzzaman et al, 2020Hasanuzzaman et al, , 2021.…”

“…Cultivated peanut/groundnut (A. hypogaea L.), an allotetraploid crop, is one of the most valuable and economic oilseed food crops globally (Agarwal et al, 2018;Bertioli et al, 2019;Chen X. et al, 2019;Zhuang et al, 2019). This crop is being widely cultivated in the tropical and subtropical regions globally; however, several abiotic and biotic factors significantly affect its growth and production, including many important agronomic traits (Agarwal et al, 2018;Gangurde et al, 2020Gangurde et al, , 2021Kumar et al, 2020;Pandey et al, 2020;Shasidhar et al, 2020;Sinha et al, 2020;Jadhav et al, 2021;Soni et al, 2021;Aravind et al, 2022;Bomireddy et al, 2022;Liu et al, 2022;Patel et al, 2022). Therefore, it is vital to identify new potential genes associated with multiple stress tolerance and trait improvement in peanut for better protein-rich food supply, particularly in Asian and African countries.…”
