Aegilops squarrosa (DD) as female parent was crossed with wheat (Triticum aestiu m,AABBDD),emmer(AABB),rye (Secale cereals,RR) or Triticale sp.(AABBRR) respectiv ely.Embryos of different dates after fertilization were taken down,grafted and c ultured in the test tubes under sterilized conditions.Altogether 1090,embryos we re grafted from 101 cross combinations.They differentiated into 31 whole seedlin gs(2.84%),20 rootless seedlings (1.83%),24 para embryo buds (2.2%),66 calli (6.0 5%),and 950 undifferentiated embryos (87.16%).The 31 whole seedlings consist of 21 wheat plants,5 emmer plants,2 rye plants and 3 triticale plants.These experim ents showed that distant hybrids could be obtained from crossing dipoid Aegilops squarrosa as female parent with wheat,rye,or triticale through embryo culture.
