Chromosome and genome composition of a Triticum × Thinopyrum hybrid by classical and molecular cytogenetic techniques

Triticum-Thinopyrum amphiploids arose from the need to obtain forage grasses highly resistant to pest, drought, soil salinity and frost and they can be used as efficient bridges to transfer desired genes from wheatgrass species to wheat. One of them is trigopiro SH16 INTA, it was introduced in Argen...
