Franklin withstands barley yellow dwarf

1992 trials at three severely infested sites in Tasmania found Franklin barley performed credibly when infected with barley yellow dwarf virus.

Researchers report that while infection rates were similar between Franklin, Proctor and Triumph, overall yields were much higher for Franklin (3.1 t/ ha). In the absence of virus infection the cultivars yield similarly.

At two sites where infection levels were very high, Franklin performed significantly better when established by direct drilling (3.3 versus 2.9 t/ha). The other two cultivars performed better when sown into cultivated seed beds. The reason for this difference is not yet known.
