1.Diploids and induced autotetraploids of 2 two-rowed and 3 six-rowed cultivated varieties of Hordeum sativum and a two-rowed wild species, H. spontaneumC. Koch var. transcaspicum Vav. were used in the crossing experiments.
2.Seventeen eu-triploids with 2n=21 and 2 hypo-triploids with 2n=20 chromosomes were obtained from a total of 2721 florets of the crosses 4x×2x.
3. The cross 2x×4x gave a high percentage of seed setting with an exception of Hosomugi in 1952, the seeds, however, did not germinate.
4. Unexpectedly, two hyper-tetraploids, 2n=29 and 30, were obtained from the cross 4x×2x in H. spontaneum C. Koch var. transcaspicum Vav.
5. The percentage of seed setting and of germination differed in different cross combinations and different years.
