Addition of Aegilops biuncialis chromosomes 2M or 3M improves the salt tolerance of wheat in different way

Abstract Aegilops biuncialis is a promising gene source to improve salt tolerance of wheat via interspecific hybridization. In the present work, the salt stress responses of wheat-Ae. biuncialis addition lines were investigated during germination and in young plants to identify which Aegilops chromo...
