Thirteen wheat (Triticum aestivum L.) cultivars (predominantly winter types) of diverse origin were crossed with diploid H. bulbosum. The seed set values in wheat H. bulbosum crosses ranged from 1.3% to 22.7%. A marked variation in seed set values between the spikes of the same cultivar suggested that apart from crossability genes environmental factors and crossing techniques also influence the frequency of seed set. Contrary to the previous reports, results also indicated that the F1 hybrids between wheat and H. bulbosum can be obtained without resorting to embryo culture.
