Confirmation of chloride deficiency as the cause of leaf spotting in durum wheat grown in the Australian northern grains region by Schwenke, G.D., Simpfendorfer, S.R., Collard, B. C. Y.

“…Among commercial varieties, Jandaroi was highly sensitive to low Cl–, Caparoi was moderately sensitive, and EGA Bellaroi was tolerant. Several elite durum breeding lines grown in 2010 showed considerably reduced leaf spotting compared with Jandaroi under low Cl– conditions, indicating potential for conventional breeding to reduce the potential impact of low Cl– soils on durum production in northern Australia.…”
