Molecular cytological characterization of two novel durum--Thinopyrum intermedium partial amphiploids with resistance to leaf rust, stem rust and Fusarium head blight.

Abstract excerpt

Thinopyrum intermedium, a wild relative of wheat, is an excellent source of disease resistance. Two novel partial amphiploids, 08-47-50 and 08-53-55 (2n = 6x = 42), were developed from wide crosses between durum wheat and Th. intermedium. Meiotic analysis showed that pollen mother cells of the two partial amphiploids formed an average 20.49 bivalents for 08-47-50 and 20.67 bivalents for 08-53-55, indicating that...
