Studies on morphology, cytogenetics and fertility of BC1 F1 of hybrid F1 between Elymus dahuricus and Hordeum brevisubulatum

摘要：

The hybrid F1 between Elymus dahuricus (2n=42) and Hordeum brev isubulatum (20n=28) is strong in heterosis.However it is highly sterile.The hybrid F1 was backcrossed by recurrent parent H.brev isubulatum to restore fertility to hybrid F1, and finally the BC1 F1 was got (LI et al.,2004).The morphology, cytogenetics and fertility of BC1 F1 of hybrid F1 between E.dahuricus and H.brev isubulatum were studied to provide scientific basis for selection and utilization of excellent lines of cross descendents.
