Description

Yonggang Lv and co-authors pinpoint a gene locus that makes hybrids between two prized rice groups sterile, in a 2024 study. Basmati rice, famed for its aroma, and temperate japonica, a main cultivated group, resist cross-breeding: their hybrids are often male-sterile, blocking the transfer of good traits. The genetic basis between these two groups was unknown.

Crossing a temperate japonica variety with a basmati one and tracking inheritance through several backcross generations, the team mapped the culprit, named S67, to a stretch of chromosome 1. The locus kills hybrid pollen in a way that favors passing on the japonica version of the gene, distorting inheritance. The authors say the find fills the gap for this particular pairing and lays groundwork for studying hybrid sterility across rice groups. Knowing the locus also helps breeders design compatibility lines that could finally let the two groups' strengths combine.
