[Morphology, cytogenetics of intergeneric hybrid between Aegilops taucchii and Dasypyrum villosum].
Yi Chuan. 2004 Mar; 26(2):189-94.YC

Abstract

"Aegilops tauschii x Dasypyrum villosum" F1 hybrids were obtained by the combination of hybridization and embryo culture in vitro. Chromosome pairing behavior in meiosis of the hybrid F1 was carried out. Results showed that in an average , 1.25 rod bivalents were observed in one PMC, meiotic configuration was 2n=14=11.49 I + 1.25 II (Xta=1.25) and most of PMCs possessed 1 approximately 5(rod) bivalens, indicating that the relatively high homeology was detected between the D genome of Ae. tauschii and the V genome of D. villosum. The morphological differences between F1 hybrids and their parents were significant. F1 plants were highly self-sterile, but partially self-fertile after treated by chromosome doubling technique.
