Description
Minglei Song and fifteen co-authors engineered hybrid rice in 2024 that clones itself through seed while keeping normal fertility. Clonal seed, called apomixis, would let farmers replant hybrid seed without losing its edge. Early versions cloned poorly or set few seeds, blocking farm use.
The team paired a boosted egg-cell trigger with three disabled meiosis genes in an elite hybrid. Over ninety-five percent of the offspring came out clonal, and seed set stayed high. Field traits matched the parent hybrid. Self-cloning hybrids with full fertility move from proof of concept toward real breeding.
