Group of experiments were carried out to verify possibility of gene introgression from common wheat into Aegilops.
The artificial indoor crossbreed was conducted using 7 genotypes from 4 wheat relative species as female, and common wheat as male.
The experiment result shows that different species has variable cross ability.
Among the 4 Aegilops species, the highest cross rate is from the combination of Aegilops tauschii Triticum aestivum (46.49% for genotype Ae42, 22.58% for Y92), the second is from Aegilops ovata T.
aestivum (14.76% for Y100, 12.11% for Ae23), the third is from Aegilops cylindrica T.
aestivum (2.23% for Ae7, 8.50% for Y145), and the lowest is from Aegilops speltoides T.
aestivum (0.19%).
Hybrid embryos from different combinations have different ability of callus initiation and germination.
The hybrid embryos from A.
ovata/T.
aestivum and Ae.
tauschii/T.
aestivum have a higher level of callus initiation and germination.
Ae.
cylindrica/T.
aestivum has a middle level, while the Ae.
speltoides has a lower level.
The interspecific hybrids between Aegilops and common wheat have so low fertility.
In back-crosses, the seed-set rate of hybrids of Ae.
ovata/T.
aestivum is 3.71% and 4.36% respectively back-crossed with male and female parents, while for hybrids of Ae.
cylindrica/T.
aestivum, they were 0 and 0.33% respectively, and for Ae.
tauschii/T.
aestivum, 0.33% and 0 respectively.
On selfing of the hybrids, the seed-set rate is 0 (no seed set from 9750 florets) for the combination of Ae.
cylindrica/T.
aestivum, 0.044% (3 selfed seeds out of 6870 florets) for Ae.
ovata/T.
aestivum and 0 (no seed set from 7253 florets) for Ae.
tauschii/T.
aestivum.
The research suggests that the probability of gene introgression from T.
aestivum into Aegilops species is very low in nature.
