众所周知,在小麦锈病研究中,侵染型是抗病育种中品种抗病性鉴定的依据,也是抗性遗传研究中根据表现型分析基因型的依据。所以,正确地鉴定和记载侵染型,是小麦锈病研究中最基础的工作。Loegering在生物间遗传学中提出不通过杂交根据侵染型推导寄主和病原物基因型的方法,尤其是外部相关法,即通过已知基因和未知基因品种对锈菌的反应来确定未知基因品种的抗性基因,已在国际普遍采用。侵染型可因寄主、病原物或环境不同,寄主或病原物的混杂程度以及接种量的不同等发生变化,所以,正确地确定侵染
It is well-known that in wheat rust research, invasiveness is the basis for the identification of disease resistance in resistance breeding and is also the basis for analysis of genotypes based on phenotypes in resistance genetic studies. Therefore, the correct identification and record of infection is the most basic work in wheat rust research. Loegering proposed in inter-biogenetics methods that do not deduce host and pathogen genotypes by infection, particularly by the external correlation method, by crossing to determine the unknown gene species through the reaction of the known genes and the unknown gene species to rust The resistance gene has been widely adopted in the world. Infections can vary due to differences in host, pathogen or environment, host or pathogen contamination, inoculum size, etc. Therefore, infection is correctly identified
