The Kansas State University announces the release of a nested association mapping population (NAM) with a total of 2,133 recombinant inbred lines (RILs) developed from ten bi-parental sub-populations. These 2,133 RILs were derived from 10 diversified founder lines each crossed separately to RTx430 to develop ten bi-parental mapping sub-populations and released by the Kansas State University (KS) in July 2019. Extensive field studies on the founder lines having wide genetic and geographical diversity simply proved the unique and distinguishable nature of the developed KS-RTx430NAM population for the traits related to biotic and abiotic stresses. The population is currently in F9 and reached the maximum homozygosity with genetic purity and uniformity with each RIL. All RILs have been genotyped through genotype-by-sequencing (GBS) using an illumina HISeq 2500 with a high-output flowcell and 100-cycle single-end sequencing. KS-RTx430NAM will serve as a new genetic resource and for research and developmental purpose for the exploitation of wide genetic diversity of many complex yield traits.
