Hybrid seed production is a labour-intensive manual process that limits fully mechanized hybrid rice breeding. We identify GSE3 as a gene that regulates grain size and demonstrate that fully mechanized hybrid seed production and increased seed number can be achieved using small-grain alleles of GSE3 in male sterile lines.
