DOI: 10.1007/s00122-020-03573-5
Abstract: Key message Simulations showed that hybrid performances issued from an incomplete factorial between segregating families of two heterotic groups enable to calibrate genomic predictions of hybrid value more efficiently than tester-based designs. Abstract Genomic selection… read more here.
