Breaking the reproductive barrier to create inter-subspecific hybrid rice. The asynchronous diurnal floret opening time (DFOT) of indica and japonica leads to prezygotic reproductive isolation, and consequently, very low efficiency of hybrid seed production. This may be improved by modifying DFOT genes. Hybrid sterility caused by postzygotic reproductive isolation is also a major obstacle, and now we can create fertile indica–japonica hybrids by manipulating hybrid sterility genes using either natural non-functional alleles or knockout mutants by CRISPR.
