Assessment of resistance and inheritance to barley yellow Dwarf virus disease (BYDV) in five wheat cultivars Triticum aestivum L

Abstract

The objectives of this investigations were: (1) to evaluate methods of detecting and measuring resistance among cultivars, (2) to identify sources of BYDY resistance and (3) to determine the nature of inheritance controlling BYDV resistance. Experimental materials included four winter-type and one spring- type wheat and the resulting F1, F2, F3, BC-a and BC-2 generations from crosses among the five cultivars. Two studies were conducted. The first was conducted in the greenhouse where an assessment of the parental lines was made with regard to the injury of aphid feeding and aphids plus the virus. A field experiment was established to obtain information on the nature of inheritance.
