摘要
小麦条锈病(Puccinia striformis West.)的流行受渚多因素的影响,品种的感病性是其中的重要因素。我国自50年代以来,条锈病曾发生3次全国性大流行和多次局部地区流行,
As the results indicate, the developmental scale and speed of Stripe rust charges with different susceptability of wheat breeds. The epidemic curves on various wheat breeds arc best fitted by Gompertz model. According to the value of epidemic rate(k) in the model, the 8 breeds are classified into 3 susceptability levels,i.e. Highly(k≥0.1), medium(0.06<k<0.10) and least susceptable(k≤0.06). Approaches concerning the prevention of Stripe rust epidemics in susceptable areas of southern Gansu province are discussed in the paper.
