Novel perpetual genetic population development and genome assembly of superior maize inbred lines provide insights into genetic improvement.

ABSTRACT:

Background

Maize, as an important dual-purpose grain and forage crop all over the world, exhibits extensive heritable and phenotypic diversity. Taking the breeding patterns as the core and developing advanced genetic breeding tools with the characteristics of Chinese maize germplasms will significantly advance the genetic dissection of complex agronomic traits and facilitate targeted genetic improvement in maize.

Results

Here, based on the predominant heterotic pattern "X group × SPT group," we developed the first whole chromosome substitution line (WCSL) population in maize, designated the MOSAIC population. We ensured the near-complete substitution of single chromosome and consistent genetic backgrounds as much as possible in each WCSL from the MOSAIC population. The de no
