Abstract

Oryza longistaminata (OL), an AA-genome African wild rice which can propagate clonally via rhizome, is an important germplasm for improvement of Asian cultivated rice, however recessive lethal alleles can hitchhike clonal propagation in heterozygous state. Selfing of OL is difficult due to its self-incompatibility, but simple selfing of hybrid progeny between OL and O. sativa is effective to disclose and eliminate recessive lethal alleles. Here, we identified an exhibited albino-lethal phenotype mutant, from an F
