Hyvido Neo - New virus-resistant hybrid barley from Syngenta (x)

In the case of viruses attacking wheat, early sowings, as well as mild winters, contribute to an increase in virus pressure in the populations of winter wheat and winter barley. Responding precisely to the vintage of the year and consequently to the needs of producers, Syngenta has introduced under the brand Hyvido Neo: the SY Zoom and the SY Kestrel hybrid barleys.

Viruses that harm cereals are generally known to be transmitted by aphids on monocots (barley yellow dwarf virus) or by cereal flies (wheat dwarf virus). The barley yellow dwarf virus (BYDV) has five serotypes (MAV, PAV, RPV, RMV, SGV) which are differentiated based on the vector aphids, and which are present in our country. In the case of aphids, both winged and wingless forms are capable of transmitting the virus. The MAV and PAV serotypes are the most widespread. The vector for the MAV serotype is the cereal aphid (Sitobion avenae, syn.: Macrosiphum avenae), while the PAV serotype vectors are the cereal aphids (S. avenae) and the bird cherry-oat aphids (Rhopalosiphum padi). The genetically distinguishable RPV serotype, which is named the cereal yellow dwarf virus, is primarily vectored by the bird cherry-oat aphid (Rhopalosiphum padi).
