Summary

Improvements in the success of doubled haploid production have been achieved partly by screening new accessions of Hordeum bulbosum. In order to assess levels of variation within stocks of this species, rates of embryo differentiation from the cross between H. vulgare × H. bulbosum were recorded for selections derived from two different stocks of H. bulbosum. There was little difference within stocks for this character despite variation in the morphology and banding patterns of two enzyme systems of one of the stocks. It is proposed that to obtain further increases in success rates a few selections from many accessions of H. bulbosum should be screened rather than many selections from a few stocks.
