We created waxy corn hybrids by CRISPR-Cas9 editing of a waxy allele in 12 elite inbred maize lines, a process that was more than a year faster than conventional trait introgression using backcrossing and marker-assisted selection. Field trials at 25 locations showed that CRISPR-waxy hybrids were agronomically superior to introgressed hybrids, producing on average 5.5 bushels per acre higher yield.
