UK: Mild weather may cause barley mosaic virus
"Symptoms in non-resistant varieties are the strongest we have seen for many years. So now is a good time for growers to check their winter barley fields for mosaic virus infection, warns Mr Fenwick, according to The Breezi Publishing Company Limited, March 19.
This soil-borne virus can reduce yields by 30-40%, which is why Nickerson select for complete resistance as a high breeding priority.
Both the companys malting variety Cassata and the feed variety Retriever are newly HGCA-recommended on the winter barley list for 2007-8 and are resistant to barley mild mosaic virus (BaMMV) and to barley yellow mosaic virus (BaYMV) strain 1.
