"Identification of several small main-effect QTLs and a large\r\nnumber of epistatic QTLs for drought tolerance related traits\r\nin groundnut (Arachis hypogaea L.)"^^ . "Cultivated groundnut or peanut (Arachis hypogaea\r\nL.), an allotetraploid (2n = 4x = 40), is a self pollinated\r\nand widely grown crop in the semi-arid regions of\r\nthe world. Improvement of drought tolerance is an\r\nimportant area of research for groundnut breeding programmes.\r\nTherefore, for the identification of candidate\r\nQTLs for drought tolerance, a comprehensive and refined\r\ngenetic map containing 191 SSR loci based on a single\r\nmapping population (TAG 24 9 ICGV 86031), segregating\r\nfor drought and surrogate traits was developed. Genotyping\r\ndata and phenotyping data collected for more than\r\nten drought related traits in 2–3 seasons were analyzed in\r\ndetail for identification of main effect QTLs (M-QTLs)\r\nand epistatic QTLs (E-QTLs) using QTL Cartographer,\r\nQTLNetwork and Genotype Matrix Mapping (GMM)\r\nprogrammes. A total of 105 M-QTLs with 3.48–33.36% phenotypic variation explained (PVE) were identified\r\nusing QTL Cartographer, while only 65 M-QTLs with\r\n1.3–15.01% PVE were identified using QTLNetwork. A\r\ntotal of 53 M-QTLs were such which were identified using\r\nboth programmes. On the other hand, GMM identified 186\r\n(8.54–44.72% PVE) and 63 (7.11–21.13% PVE), three and\r\ntwo loci interactions, whereas only 8 E-QTL interactions\r\nwith 1.7–8.34% PVE were identified through QTLNetwork.\r\nInterestingly a number of co-localized QTLs controlling\r\n2–9 traits were also identified. The identification of\r\nfew major, many minor M-QTLs and QTL 9 QTL interactions\r\nduring the present study confirmed the complex and\r\nquantitative nature of drought tolerance in groundnut. This\r\nstudy suggests deployment of modern approaches like\r\nmarker-assisted recurrent selection or genomic selection\r\ninstead of marker-assisted backcrossing approach for\r\nbreeding for drought tolerance in groundnut."^^ .
