Identification of resistance to new virulent races of rust in sunflowers and validation of DNA markers in the gene pool.

Phytopathology - 1 Feb 2011

Qi Lili, Gulya Tom, Seiler Gerald J, Hulke Brent S, Vick Brady A

Abstract excerpt

Sunflower rust, caused by Puccinia helianthi, is a prevalent disease in many countries throughout the world. The U.S. Department of Agriculture (USDA)-Agricultural Research Service, Sunflower Research Unit has released rust resistant breeding materials for several decades. However, constantly coevolving rust populations have formed new virulent races to which current hybrids have little resistance. The objectives...
