The Occurrence of a Second Race of Rust (Puccinia Helianthi) in Sunflower Crops in Eastern Australia
Race 3 was identified among rust collections made in Jan. 1983 and subsequently from the main sunflower growing areas of Qd and was pathogenic on all commercial hybrids with immunity from race 1 conferred by the R1 gene. The possibility that gene R2 carrying resistance to both races 1 and 3 is prese...

Zusammenfassung: | Race 3 was identified among rust collections made in Jan. 1983 and subsequently from the main sunflower growing areas of Qd and was pathogenic on all commercial hybrids with immunity from race 1 conferred by the R1 gene. The possibility that gene R2 carrying resistance to both races 1 and 3 is present in the wild Helianthus argophyllus is being investigated.
