De Novo Genome Assembly of 12 Founder Inbred LinesPublication: Wang, B., Hou, M., Shi, J. et al. De novo genome assembly and analyses of 12 founder inbred lines provide insights into maize heterosis. Nat Genet (2023). DOI: 10.1038/s41588-022-01283-w.A key factor contributing to the success of hybrid maize is breeding of improved parental inbred lines and assigning them to female and male heterotic groups that allow maximum exploitation of heterosis. The three major heterotic groups, Stiff Stalk (SS), Lancaster Surecrop (Lancaster or LSC, also called Nonstiff Stalk or NSS) and Iodent (IDT), were developed in the United States. In China, both local germplasm (such as Tang SiPingTou (TSPT) and LvDa Red Cob (LRC)) along with germplasm from the US, were used to develop parental inbred lines, leading to the formation of additional heterotic groups, including the PA, TSPT, LRC, PB, X-group, and Suwan groups. 12 maize founder inbred lines (FILs) were selected as representatives of nine heterotic groups of maize (SS1, SS2, PA, X-group, Lancaster1, Lancaster2, TSPT, IDT, PB) for de novo assembly and annotation, providing a valuable genomic source for the maize research community.
