Introgression of pre-harvest sprouting resistance from hexaploid wheat into high yielding durum wheat germplasm

Pre-harvest sprouting (PHS) is a critical factor affecting wheat producing regions characterized by rainfall and high humidity combined with cool temperatures at harvest. This phenomenon particularly important in durum (Triticum L.), which generally susceptible to PHS, contrast common aestivum L.) expresses better resistance. The transfer of PHS from hexaploid into tetraploid germplasm one option for genetic improvement, because the two species share related sub-genomes. In present study, through interspecific hybridization modified backcross approaches, we developed experimental lines that showed greater resistance than recurrent parent, some expressing performance resistant donor. introgression did not negatively impact additional traits background several derived expressed superior grain yield quality when compared parent. These represent promising resource development new cultivars. Our results demonstrate can be transferred improve germplasm.
