Genetic characterization of the chromosome single-segment substitution lines of O. glumaepatula and O. barthii and identification of QTLs for yield-related traits

Oryza glumaepatula and Oryza barthii are AA-genome wild species in Oryza genus. In order to effectively mine and transfer beneficial genes from these wild species in genome-wide by distant hybridization, in the present study, the chromosome single-segment substitution lines (SSSLs) were developed using O. glumaepatula and O. barthii as donors and elite indica cultivar, HJX74, as a recipient. A total of 168 homozygous SSSLs of O. glumaepatula...
