Molecular cytogenetic identification of a wheat – Thinopyrum ponticum substitution line with stripe rust resistance

Thinopyrum ponticum (Th. ponticum) (2n = 10x = 70) is an important breeding material with excellent resistance and stress tolerance. In this study, we characterized the derivative line CH1113-B13-1-1-2-1 (CH1113-B13) through cytological, morphological, genomic in situ hybridization (GISH), fluorescence in situ hybridization (FISH), expressed sequence tag (EST), and PCR-based landmark unique gene (PLUG) marker analysis. The GISH analysis revealed...
