条锈菌（Pucciniastriiformis）是小麦（Triticumaestivum2n = 6x= 42）栽培中的一种重要病害。限制由病害引起的产量损失的最经济的方法在于培育具有遗传决定的抗感染性的品种。目前大多数品种的抗性都是由于它们在不同组合中携带的几个主基因的活性。然而，必须不断寻找新的抗性来源，因为病原体中的突变或体细胞重组可产生遗传变异体，目前使用的特定抗性基因或基因组合不再有效。
YELLOW rust (Puccinia striiformis) is a hazard to the cultivation of wheat (Triticum aestivum2n= 6x= 42) in many temperate regions. The most economic method of limiting losses of yield caused by the disease lies in the cultivation of varieties with genetically determined resistance to infection. Most current varieties owe their resistance to the activities of a few major genes which they carry in various combinations. New sources of resistance, however, must be sought continually because mutation or somatic recombination in the pathogen can give rise to genetic variants against which particular resistance genes or combination of genes, in current use, cease to be effective.
