Genome characterization of a synthetic triticum x thinopyrum (poaceae) amphiploid using in situ hybridization

Mostrar todas las versiones(3)

"Trigopiros" derive from crosses between different species of Triticum L. and Thinopyrum Löve. These synthetic amphiploids are designed with the aim to obtain cereals similar to wheat but which are perennial, resistant to diseases and to the salinity of the soils. Moreover, they allow the...
