Seed set limits use of certain barley ( Hordeum vulgare L.) genotypes in H. bulbosum L. doubled‐haploid production. This study was conducted to determine the genetic basis of low seed set in the spring barley cultivar Apex crossed with H. bulbosum . Two hundred F 2 plants, all having Apex as one parent and either Havila, Krystal or Roland as the other parent, were crossed with one clone of H. bulbosum . Parameters of haploid production efficiency (seeds/100 florets, embryos/100 seeds, and plants/100 embryos), were measured. Segregation ratios in the three F 2 populations suggest that reduced seed set in Apex is governed by a single codominant gene. Haploid production efficiencies were intermediate between the two parents and were acceptable for applied plant breeding.
