A total of 90,000 capture probes derived from wheat and Thinopyrum elongatum were integrated into one chip, which served as an economical genotype for explorating Thinopyrumspecies and their derivatives. Thinopyrum species play a crucial role as a source of new genetic variations for enhancing wheat traits, including resistance to both abiotic and biotic factors. Accurate identification of exogenous chromosome(s) or chromosome segments or genes is essential following the introduction of alien genetic material into wheat, but this task remains challenging.

In this study, we crossed MY3478 (2 = 4 = 28, AABB) as the maternal parent with the stripe rust-resistant SY41 (2 = 2 = 14, DD) as the paternal parent to construct the new hexaploid wheat line NA0928 through natural allopolyploidization. Agronomic traits and the cytology of the S-S generations of NA0928 were analyzed.

In this study, the wheat- alien disomic substitution line W16998 was obtained from the BCF progeny of a cross between the common wheat 'Chinese Spring' (CS) and Roth (serial number: SY159//CS). This line was identified using cytogenetic techniques, analysis of genomic in situ hybridization (GISH), functional molecular markers (Expressed sequence tag-sequence-tagged site (EST-STS) and PCR-based landmark unique gene (PLUG), fluorescence in situ hybridization (FISH), sequential fluorescence in situ hybridization-genomic in situ hybridization (sequential FISH-GISH), and assessment of agronomic traits and powdery mildew resistance.

View Article and Find Full Text PDFLeymus mollis (2n = 4x = 28, NsNsXmXm) possesses novel and important genes for resistance against multi-fungal diseases. The development of new wheat-L. mollis introgression lines is of great significance for wheat disease resistance breeding.
View Article and Find Full Text PDFLeymus mollis (2n = 4x = 28, NsNsXmXm) is an important tetraploid species in Leymus (Poaceae: Triticeae) and a useful genetic resource for wheat breeding because of the stress tolerance and disease resistance of this species. The development of Triticum aestivum (common wheat) - L. mollis derivatives with desirable genes will provide valuable bridge materials for wheat improvement, especially regarding powdery mildew resistance genes, which are rarely documented in L.
