Development and validation of an exome-based SNP marker set for identification of the St, J^r and J^vs genomes of Thinopyrym intermedium in a wheat background.

ABSTRACT:

Key message

Cytogenetic analysis and array-based SNP genotyping of wheat- Th. intermedium introgression lines allowed identification of 634 chromosome-specific SNP markers across all twenty-one chromosomes of Th. intermedium (StJ ^r J ^vs , 2 n  = 6 x  = 42). Thinopyrum intermedium (2n = 6x = 42, StJ^rJ^vs) is one of the most promising reservoirs of useful genes including tolerance to abiotic stresses, perenniality and disease resistance not available in the cultivated bread wheat. The transfer of genetic diversity from wild species to wheat offers valuable responses to the effects of climate change. The new array-based single-nucleotide polymorphism (SNP) marker technology provides cheap and easy-to-use molecular markers for marker-assisted
