Molecular cytogenetics and St-chromosome-specific molecular markers development of novel stripe rust resistant wheat–Thinopyrum intermedium as well as wheat–Thinopyrum ponticum substitution lines
Abstract:Background
Owing to the excellent resistance to abiotic and biotic stress, Thionpyrum intermedium (2n = 6x = 42, JJJsJsStSt) and Thinopyrum ponticum (2n = 10x = 70) are both widely utilized in wheat germplasm innovation programs. Disomic substitution lines (DSLs) carrying one pair of alien chromosomes are valuable bridge materials for novel genes transmission, FISH karyotype construction and specific molecular marker development.
