“…In the United States and United Kingdom, independent and interconnected bi-parental "mapping" families have been studied (Dong et al, 2018;Gifford, Chae, Swaminathan, Moose, & Juvik, 2015) alongside panels of diverse germplasm accessions for GWAS . Further developments calibrating GS with very large panels of parents and cross progeny are underway (Dalton, 2013;Guo et al, 2013;Hwang, Cho, et al, 2014;Rambaud et al, 2013;Ślusarkiewicz-Jarzina et al, 2017;Wang et al, 2011;Zhang et al, 2012). However, there is still significant genotype specificity and these methods need "in-house" optimization and development to be used routinely.…”
