- Abstract
The enzyme-linked immunosorbent assay (ELISA) was used to determine the concentration of barley yellow dwarf virus (BYDV) in leaves of spring wheat Triticum aestivum L. cv. 'Fukuhokomugi', Leymus angustus (Trin.) Pilger (Altai wild rye) and their F1 hybrids inoculated at the 2- to 3-leaf stage. The BYDV isolate "Cloutier" (serotype PAV) was used. The results showed that L. angustus confers immunity or strong resistance to the virus. Significant multiplication of the virus occurred in 'Fukuhokomugi' which expressed an intermediate level of tolerance to the disease under field conditions. The F1 haploid hybrids of 'Fukuhokomugi' × L. angustus expressed a level of resistance almost equal to that of their wild parent, with a low concentration of virus appearing 16 days after inoculation and no more afterwards. The discovery of BYDV resistance in L. angustus and the expression of this character in the F1 hybrids provide new opportunities for the enlargement of the gene pool for BYDV resistance in wheat.
