Molecular cytogenetic identification of two wheat–Thinopyrum ponticum substitution lines conferring stripe rust resistance

Distant hybridizations are important for developing common wheat germplasm. Thinopyrum ponticum (2n = 10x = 70), which is a wild relative of wheat, has numerous advantages for enhancing the tolerance of plants to biotic and abiotic stresses. ES-11 and ES-12 are two stable lines derived from a cross between the Triticum aestivum–Th. ponticum partial amphiploid line Xiaoyan784 (2n = 8x = 56) and the wheat Abbondanza nullisomic lines (2n = 40)...
